Brake upgrade for Discovery 2?

[twr7cx]

Are there any serious brake upgrades for the Discovery 2?

I know the later D2a's had improvements to the front callipers and brake master cylinder. There's always the simple aftermarket upgrades like brake rotors and pads:

But is there any serious brake upgrades? Larger callipers? More pistons? Larger rotors?

With the larger tyres, added weight of the equipment on the vehicle, height increases etc., it definitely puts a lot more strain on the brake system.

[Yorkie]

are the pistons stuck on that one? :o

[slug_burner]

discs and calipers are available from places like these:

If you cant do Disco 2 parts try Range Rover P38. You could speak to your mechanic.

I recently fitted cross drilled/slotted rotors and they seem better.They were never poor to start with.
I suggest you flush your brakes at least once a year.If you have a nannycom or can borrow one its a VERY easy job.
If not,search on AULRO there are methods of getting the ABS system to run whilst bleeding like Nannocom does.
I find mine do get spongy over time,I simply flush them on an annual basis and they are good again.

If the std brakes are good for the full gvm plus 3000 kgs pushing on the towbar I wouldn't worry. Take a series 3 swb for a drive down a long winding hill, then you would consider better brakes

I know the later D2a's had improvements to the front callipers and brake master cylinder. There's always the simple aftermarket upgrades like brake rotors and pads:


It looks like the D2 has 2 different front calipers (early 48mm, late 45mm) and the brake master cylinder is the same for all D2. (thanks Rick130!)
From what I can calculate, for a given line pressure the early caliper gives about 13.7% increased clamping pressure.

Does anybody know what the difference is between the early and late Disco2 brake booster by any chance?
Did the later brake booster increase brake line pressure to compensate for reduced piston size in the calipers?

It may be easy to see where I'm going with this.

I can't offer anything on what you've raised, but I'm interested so thought I would consult Microcat for the D2 part listings for clues. To that end I offer the following:

There's a wide variety of part numbers listing for the D2 range:

Master Cylinder Assembly Brake:



SJC100430 [ - (V)XA222500 ] (http://lr.ru/search'type=catalog&query=SJC100430) - doesn't seem to have any third party versions of this part number, only genuine lists and alternative part numbers (SJC100430, SJC100432 and SJC000110)


SJC100431[ (V)XA222501 - (V)XA232916 ] (http://lr.ru/search'type=catalog&query=SJC100431) - Microcat lists as superseding SJC100430. Doesn't list with suppliers only alternative part numbers (SJC100430, SJC100432 or SJC000110)
SJC100432[ (V)XA232917 - (V)2A999999 ] (http://lr.ru/search'type=catalog&query=SJC100432) - Microcat lists as superseding SJC100431. Listed as superseded by SJC100430
SJC000110[ (V)3A000000 - ] (http://lr.ru/search'type=catalog&query=SJC000110) - Microcat lists as superseding SJC100432. Looks to be available for purchasing

SJC100440[ - (V)XA222500 ] (http://lr.ru/search'type=catalog&query=SJC100440)- doesn't list with suppliers only alternative part numbers (SJC000100 or SJC100442)
SJC100441[ (V)XA222501 - (V)XA232916 ] (http://lr.ru/search'type=catalog&query=SJC100441) - suppliers cross referencing to SJC000100 and SJC100442
SJC100442[ (V)XA232917 - (V)2A999999 ] (http://lr.ru/search'type=catalog&query=SJC100442) - Microcat lists as superseding SJC100440 and SJC100441. Suppliers list as superseded by SJC000100
SJC000100[ (V)3A000000 - ] (http://lr.ru/search'type=catalog&query=SJC000100) - looks to be available for purchasing

You are perhaps onto something in that there seems to be two different ranges of Master Cylinder Assemblies that in their most recent part number result in SJC000100 (for later vehicles) and SJC000110 (for earlier vehicles). Perhaps their difference is the line pressure as you've suggested?


For the front disc brake callipers:

STC1915 [ - (V)2A999999 ] (http://lr.ru/search'type=catalog&query=STC1915) (also used on Range Rover 1994 - 2001 (P38 I assume?))
STC1916 [ - (V)2A999999 ] (http://lr.ru/search'type=catalog&query=STC1916) (also used on Range Rover 1994 - 2001 (P38 I assume?))

SEG000060 [ (V)3A000000 - ] (http://lr.ru/search'type=catalog&query=SEG000060)
SEG000030 [ (V)3A000000 - ] (http://lr.ru/search'type=catalog&query=SEG000030)

Two very distinct part numbers there for the earlier and later vehicles. All four still seem to be available from suppliers and cannot find any information on being able to exchange them between vehicles.


Front caliber pistons:

STC1918 [ - (V)2A999999 ] (http://lr.ru/search'type=catalog&query=STC1918) (also used on Discovery 3, 4, Range Rover from 1994 - 2001 (P38 I assume?), Range Rover from 2002 - 2009 and Range Rover Sport from 2005 - 2009 - perhaps used in the rear in some of the later applications as brakes generally enlarged over the years?)SEK000020 [ (V)3A000000 - ] (http://lr.ru/search'type=catalog&query=SEK000020) (not listed for any vehicles other than Discovery 2)

Again two very different part numbers series with no information about being cross compatible - emphasised further that only STC1918 lists for the other vehicle models. Both still seem to be available from suppliers.


Brake pads:

SFP000210 [ - (V)2A769216 ] (http://lr.ru/search'type=catalog&query=SFP000210)
SFP500150 [ (V)2A769217 - ] (http://lr.ru/search'type=catalog&query=SFP500150) which according to Microcat superseded SFP000210

So all used the same front brake pads regardless of which callipers are fitted.


For the sake of completeness I also checked out the rears:
STC1905 for LH
and STC1906 for RH
regardless of VIN so same same all the way through - which means that later vehicles may have more rear brake bias if they're running higher line pressures with the same rear callipers as the earlier vehicles?



It may be easy to see where I'm going with this.

The higher pressure later brake master cylinder fitted with earlier larger piston brake callipers perhaps?


It's very strange that they downgraded the front brake callipers in the later vehicles, especially when the earlier setups piston were continued with in other model vehicles...

[Pedro_The_Swift]

from what i read-- I think its due to ABS software..
maybe,, happy to be shot down.. :)

Thats a huge amount of information! A massive thanks, because it also clarifies a lot of info including the multiple codes used and the inter-relationships between the codes.

Both of our info combined and little bit added to it, from what I can work out:

I've used MY03+ to represent VIN 3A0000000+ and also D2 for up to VIN 2A99999999

Brake Power Booster:
SJG500020-RHD /SJG500030-LHD is MY03+
SJG000040-RHD /SJG000050-LHD is D2
Not sure of the differences between D2 and MY03+

TRW SJB000161 I saw on an australian part label and with a google search there are a whole lot more, also with Lucas and TRW - do you know the cross-matched/superceded codes by any chance for the boosters???

Brake Master Cylinders are the same throughout, with the codes being:
SJC000100 for RHD
SJC000110 for LHD
I assume they are sided for the line output.

Front disc calipers:
SEG000030 is MY03+ RHF Caliper 45mm piston
SEG000060 is MY03+ LHF Calper 45mm piston
STC1915 is D2/P38 LHF Caliper 48mm pistons
STC1916 is D2/P38 RHF Caliper 48mm pistons

Pistons:
SEK000020 is MY03+ 45mm
STC1918 is D2/P38 48mm

Pads:
All D2 are the same.

Rear calipers:
All D2 are the same.
STC1905 for LH
STC1906 for RH


But absolutely, I'm trying to work out if the update D2's had smaller front caliper pistons, the Master cylinder is the same, if they upped the pressure in the revised brake booster. The newer calipers should be about 13.7% I think it was reduced in clamping pressure, so does the new booster subsequently increase the line pressure to suit and retain or improve brake clamping pressure. Then, if the update Booster did up the line pressure, if it will work with the earlier calipers to increase brake clamping pressure further. My feeling is that this may be the case, but I'm unaware of anybody running early calipers with a late booster to improve the brakes. Interestingly there was some talk in another thread questioning if this change was done to reduce the brake pedal spongyness and travel in the Disco2.

Was that for all of the changes in the upgrade?

SJB000161 - as you said works with a Google search but doesn't come up in Microcat for any vehicles or list on suppliers websites or even cross reference to anything. Most of the Google results are for used units from wreckers advertising on eBay UK. The code definitely was printed on the label by LR though:

SJC000100 for RHD
SJC000110 for LHD
I assume they are sided for the line output.

Silly me didn't think of need for different LHD and RHD units.



Front disc calipers:
SEG000030 is MY03+ RHF Caliper 45mm piston
SEG000060 is MY03+ LHF Calper 45mm piston
STC1915 is D2/P38 LHF Caliper 48mm pistons
STC1916 is D2/P38 RHF Caliper 48mm pistons

Again, I didn't think about the fact they would need to be different for left and right sides.

Yep, as Nissan went the other way with the TB48 GU, 51mm pistons and 26.99mm M/C and bigger discs vs 48mm pistons on all other GU's (and I think a 25mm M/C?)

It's the easy brake upgrade for a GU

[rick130]

I've read that the D2 calipers flex a bit, but all sliders flex, as do two piece 4 & 6 pot two piece calipers vs monoblocks but you need serious grip to exploit and notice the differences.

Thanks for this! Legend!

Just trying to piece things together, it looks like SJB000161 must be a RHD as they seem to be advertised in the UK and Aus. Also being TRW I'm assuming it is the later MY03+ version? Would you think similar??

That'd be a nice way to do it! Its interesting, one of the engineers that I follow on FB was also saying the LC200 has incredible brakes. Both Nissan and Toyota use 4pot fixed rotors which look excellent, but sadly they are different sizes to what can be put on to a D2, both with 32mm thickness rotors. The closest to a setup like that which I can work out is a D2 front end with L322 front rotor which is 344x30 and Audi Q5 3.0TD Brembo calipers which suit 345x30 rotors. But because the height of the L322 rotor is 76mm compared to the D2 rotor height of 91.5mm and the wider nature of fixed calipers, I'm not sure if they will fit behind standard D2/P38 18" rims without hitting the spokes. I'm also not sure because I think the Q5 Brembos have 42mm pistons.

I seriously need a set of test axles. :lol2:

Yep, I'm running 18's atm and just eyeballing, 4 or 6 spots will be a tight fit.
Up to 345 Rotors won't be an issue though [biggrin]
I was thinking of measuring to see if we could bore the calipers to 51mm. [bigwhistle]
The Nissan blokes reckon the big bore calipers look identical, just a bigger pad is used (that also fits the smaller caliper) and slightly bigger OD rotors

Oh, and I have multiple tabs open atm on AP Racing's site
It's all your fault Slunnie! [tonguewink]

I won't do anything though, I need to spend some $$ elsewhere on it atm. Various bits on order and more orders about to happen.[bigwhistle]

Sorry! :lol2:

Check out AP's CP5100 which is sized for a front standard rotor. 4 pot fixed caliper. Looks like its made for the D2 with OE being 297x25! It'd also be interesting to compare it to the Disco1/Def 4pot fixed calipers for the ventilated rotors.

What makes it hard to get good brakes is that LandRover use unconventional rotor thicknesses when compared to regular high performance brakes.

I'd be interested to hear what you think about boring the caliper!

[rick130]

From memory the Defender uses 48mm pistons?

I was thinking of 330+ rotors with custom top hats to get the offset I wanted, but it all comes down to what will fit inside the wheel.
Crazy thinking as my rotors, pads, hoses aren't even twelve months old.
Switch off the brain, Ricardo....

At least the new braided body/chassis hoses I have could be reused! [emoji849][emoji23]

Defender calipers would be the most elegant option for factory rotors.

I'd never thought of custom tophats or tophats to suit. I just thought when adapting the caliper to fit to setup the caliper offset there.

My feeling is that you could run up to around 350mm rotors with the 18's. This is bang on for using D4 rears and I suspect the calipers will almost match. Hmmm, maybe even L322 345mm fronts and D4 350mm rears with possibly D2 MY03+ booster could give significantly better braking, all still with sliding brake calipers.

[rick130]

Deefer 110/130 use 46mm pistons

[twr7cx]

For a setup requiring 18" wheels for clearance, what wheel setup are you thinking? I previously removed the factory 18" in favour of steel 16" but the range of off road tyres for 18" wheels has significantly increased in the past years.

What I'd like to do ideally is 345-350mm factory rotors with adapted Brembo fixed calipers at least on the front and uprated brake booster.

My thinking at this stage is the brakes need to be improved in both power and in capacity. Something along the lines of:

Front:
L322 dia344x30 rotors + Audi Q5 4pot Brembo type fixed calipers OE18"rims

Rear Not sure yet, but possibly:
L322 dia354x20 with L322 single pot sliding calipers if it will suit OE18" rims, or
P38a dia297x25 ventilated with matching twin pot sliding calipers.

I think these will work with rim inner clearances, but would need to actually check. Caliper adaptor plates I havent checked.

Still trying to work out the brake booster differences between early and late type.

[twr7cx]

Much, much cheaper than the genuine big brake upgrade, too

I was not aware that there was a genuine Land Rover big brake upgrade available for the Defenders.



Still trying to work out the brake booster differences between early and late type.

I would assume that the difference cannot be significant as the later part numbers are listed as superseding parts interchangeable with the earlier.


When I played with old Falcons previously, Race Brakes Sydney < https://www.racebrakessydney.com.au > used to do some custom setups (modified uprights and custom calliper mounting brackets) to be able to instal larger big brake setups such as from Brembo and AP Racing.

An interesting development that I found on Facebook this morning from LOF Clutches < Land Rover Heavy Duty Clutch kit for Defender Discovery and Td5, Tdci, (https://lofclutches.com) >:

That looks excellent, although I wonder why they didnt go to 350mm as nobody runs 17's on a Disco2. I wonder if they will do a rear setup also? I wonder what that caliper is?

[mad85]

im guess that will allow to fit 16 inch wheels? not sure though. Very few run 17 inch wheels ( i think only available if you use BMW wheels) but many run 16 inch wheels.

LOF normally produce very high quality products and reasonable prices. I have one of their clutches on my td5inside tuned d2 and till now it was well capable of taking some abuse :)

[twr7cx]

im guess that will allow to fit 16 inch wheels?

From the discussion comment on Facebook now, 17" or larger wheels would be required for fitment.



That looks excellent, although I wonder why they didnt go to 350mm as nobody runs 17's on a Disco2.

Not sure, I think 18" has become a lot more common on 4WD's over the years since the D2 was released with an 18" option. The tyre options available now are a lot better than back then for those of us actually using the vehicle off road. For me this would mean changing from 285/75R16 tyres to 285/65R18 which is about 0.3" smaller. Or if I could find 17" wheels then 285/70R17 would retain the current overall diameter.
The additional 20mm OD would also give an extra 10mm or so of bracket meat for the caliber anchor bolts to thread into.



I wonder if they will do a rear setup also?

According to the discussion on the Facebook post, yes. Front first and rear later in the future.



I wonder what that caliper is?

Not sure and they haven't responded to that question being asked. But the one in their test/display setup looks rather second hand which makes me think it must be a common unit off a production vehicle - perhaps D3/D4/RRS calliper then? Would be handy for supply, rebuild kits, etc. One commentor asked if they are Renault Megan callipers.

Theres a mod to fit range rover sport discs and calipers if you google p38 alcon replacement its next on my list when I've saved up some beer tokens

That's not working for me. Comes up with a result for fitting cheaper Range Rover Sport (L322 I assume) 360mm Brembo brake disc rotors onto the more expensive P38 Overfinch (Alcon) 365mm setup. Neither of these are Discovery 2 setups.


EDIT: actually I just recalled that Discovery 2 and P38 use the same brake calipers as standard (for the fronts the same units for the early D2 as P38, later D2 used a different front caliper that I think became the next generation of Range Rovers rear calipers) - perhaps your therefore hinting about fitting a P38 brake upgrade onto the D2?

The issues I see with this are that the front brake pads and front brake disc rotors for the Discovery 2 and P38 are different part numbers. For the brake pads this might just mean different compounds used for two different vehicles aimed at different buyers, but for the brake rotors does it mean different size rotors or different rotor offset/position? Ideally need someone with a P38 rotor to see if it fits onto and lines up on the D2 vehicle.

Apparently the P38 big brake kit Alcon part number (they supplied the kits to Overfinch) is BKF7351P19. The only site I can find with details on it is https://alltuning.net/tuning/23900/186578.html which Google Translate translates to:

EDIT 3:
Reading further in https://www.lrukforums.com/threads/for-anyone-with-stupid-alcon-overfinch-brakes.112796/ someone covered their P38 Overfinch (Alcon)'s to later Range Rover Sport Brembo 6 piston fronts and 4 piston rears. The last post in that thread (now two years old) indicates that they may have started selling the adapter brackets but they haven't been active on that forum since 2018 era.

A very nice brake conversion for the P38 and Disco II. Brings the bigger brakes form the newer models, although you need to be running 20" wheels for it. It's a shame our corporate development Thor P38 only has 18" wheels, but we've just put a new set of tyres on so it will be a while. Best contact the helpful Stuart at Armson A.E. for more details.

While their title says Discovery 2, the year range given is 2007 - 2014 for the vehicles. I suspect given the electronic park brake options that it is therefore meant for Discovery 3 and 4 vehicles rather...
Their kits also seem to be road/race focused - wonder how they would last offroad (although they do offer anti-rust rotor ring coatings, stainless steel pistons, external dust boots for extreme weather)?
I like their options for various wheel sizes but not sure I trust their system as it claims a 'Small 6 piston front and x-small 4 piston rear' setup with 304mm brake disc rotors back and front will fit behind both 15" and 16" wheels...
Overall I didn't find their pricing too scary - ticking all the desirable options got to $3,710.00 USD for a 6 piston front 304mm and 4 piston 304mm rear setup with all the optional longer life extras.

[Slunnie]

Thats pretty cool. I wonder what specs he is looking for?

[twr7cx]

I asked about if the factory master cylinder was large enough to push those big calipers:

“Brembo 18z is the kit il be releasing it for
Larger master cylinder is being developed Scotty factory fit ”

Ahhh, I know the setup. I was looking to do a 4pot Brembo setup which is pretty bloody powerful, my brother has the 18z setup on his Audi from the factory, Its used all over the VAG group including Porsche. Its a big brake 6pot setup, he's not mucking about! This will be one very impressive setup!

Update and some details from LOF Clutches

https://i.ibb.co/vkn6nqF/Screen-Shot-2020-07-30-at-9-52-18-am.png (https://ibb.co/KWvpvhP)


We are planning around £600!

all new calipers and mounting brackets!

What size wheel will they fit in
18"

[Slunnie]

Its really interesting, the LOF kit there hasn't really maxed out what they could have been, and I'd be interested to know what the rotor is and if its a custom rotor or if its an off the shelf alternative fitment that can be found anywhere. I also get the impression that the master cylinder isn't changed, so how much of a gain does it provide. I look at the big brake kit they've done for the front and rear of the Defender and think it looks like such a great setup, but its a shame this one isn't as optimised. However, the price looks good!

The one on Td5mafia however that is using the Brembo 18z kit under 18" rims, and he said will have a direct fit MC, now that kit I think will be amazing, that will be a seriously good bit of kit there and I suspect it will be a case of you getting what you pay for, and that I'd expect will have huge braking capacity and huge braking power!

[Slunnie]

It’d be interesting to know how these affect the traction control.

[rick130]

It’d be interesting to know how these affect the traction control.Probably no different to what we've done with our pads that have better bite.
If anything it'd enhance it?

The tone rings 'read' the speed difference and the BCU modulates the ABS, with bigger brakes with more bite it shouldn't need to be as aggressive?

On road my TC is pretty seamless, you really don't know is doing it's job in the wet except for the light flashing on the dash.
Very, very different to the new Triton work ute. That just dies in the arse at any hint of wheel slip or sliding with the SC. [emoji56]
Thankfully it has a dash switch. [emoji16][emoji23]

Admittedly, I think it will improve it also.

Now my roadies are just about done after 12 years, it might be time to move to 18’s or 20’s.

[twr7cx]

...I'd be interested to know what the rotor is and if its a custom rotor or if its an off the shelf alternative fitment that can be found anywhere.

Very much so. I can't say that I'd be willing to go that route if one of the main replacement items of it is only available from a single small time source overseas.

What are these big callipers like when exposed to dust, mud etc. of a 4WD when used off road? I ask as they seem to usually be fitted to road going vehicles so wonder if this is beyond their original intent and design?

of course it’s big money, brand new ap brakes aren’t cheap! Neither are custom bells, brackets, j hook machined discs... quality comes at a price


available now! Coming up to Christmas though means it probably won’t be till January now, big delays with the anodisers!


hard anodising mate


they work fine with the current master cylinder and obviously work fine with the abs/tc/Hdc as it’s simple hydraulic changes! The 6 pot kit i advice the larger servo and and master which I will be supplying an adaptor to use the l499 Range Rover servo and tc (these come with 6 and four pots as standard, the abs won’t be affected, lead time atm is as stated above /\ around January, normally around 3/4 weeks normally depending on ap stock...
international delivery is fine! And your welcome to pm me to discuss pricing directly

In response to my enquiry about pricing I received:


The full kit is £2200 that’s with the more expensive 380mm front discs and 340mm rear discs, These are factory land rover discs The next option is with 6 pot fronts and 4 pot rears that’s with discs and bells The price for that is £1650 for the front and £1450 for the rear Il send you some more pictures of the options

Not particularly clear but will advise with further details as received.

I've been following this too and this answers the questions I had re rotors. Thanks!

So the setups are approx $4000 and $5600 + Booster and M/C.

This is the setup I think is the go over the other ones. Its a serious setup with long term parts availability rather than just a little bit more with custom consumable parts.

[twr7cx]

Some further correspondence with Dean:


I have based this kit on a caliper that I used when I worked at prodrive, Subaru’s normally use Alcon calipers, we developed this kit as the HD 4 pot from ap has a thicker outer dust seal, this seal also sits further into the caliper as it has a deeper recess, I also prefer j hooked discs rather than drilled and grooved as they hold less dirt!

My own car has the l405 system on, I am just waiting on some manufactured parts to see if I can make it a plug and play effort!

The 2200 kit is much cheaper as it uses genuine land rovers discs and not 2 piece discs with bells
This is like the kit pictured
2x large ap four pot calipers front
2x medium ap four pot calipers rear
Brakes lines
Brackets
Bolts
340mm discs 4x

J hook/grooved machining (extra £200)


This is just a hd ap option, I can have it on any ap caliper!

But I had this setup on my own discovery 2 ki



This is for my off roader

6 pot fronts with 380mm discs and 4 pot rears with 340mm discs

This week I am building a 16” four out kit to try with a range of 16” wheels

To see if modulars etc fit without spacers

Iv sold 2 16” sets and both guys are running 30mm spacers

So I was unable to check and both are using them for racing


Regarding the master cylinder setup:


It is working great on my own car with just a lazer cut spacer, but it requires one hole drilling and a small amount of grinding, I could most likely source and prepare one for you if you went ahead with the kit

[twr7cx]

But then I shot LOF Clutches a message as you may recall that they’ve been developing a D2 setup and haven’t out much about it up since July.


We are just in the final stages of testing currently! But we are working on one yes [emoji846]


I think we are looking at March time in honesty D

There’s a big price difference between the LOF Clutches setup and Deans offerings. I imagine at that price point LOF Clutches is front only setup as their Extreme spec Defender offerings are considerably more expensive &lt; https://lofclutches.com/store/brakes/ &gt;

[Slunnie]

This will be interesting then to see if the brakes will fit factory D2 18" wheels then, depending on what offset the rotors and calipers run. Most fixed caliper setups these days have to run rims that are quite dished in the spokes to clear the calipers, where LandRover brakes are usually a fair bit further inboard and sit clear of the spokes and the narrowest part of the rim. I'm guessing they are close to factory offset to run 380mm discs..... but that may not be the case.

[twr7cx]

LOF Clutches have Brembos available for the front now - Discovery 2 Front EXTREMEspec Big Brake Kit 330mm - Land Rover Clutches (https://lofclutches.com/shop/brakes/brakeconversionkits/discovery-2-front-extremespec-big-brake-kit-330mm/)

The discs are a custom unit available through them only it would seem.

The brake pads are standard Brembo style and easily sourced in a variety of flavours from a variety of suppliers.

Nothing for the rear yet - apparently they're working on it though.

Nothing about the brake master cylinder and it's ability (or in ability) to run such large callipers (would they need more fluid displaced?). Dean Lapham from Total Td5 still seems to be the only brake master cylinder upgrade source using the L322 Range Rover unit.

Rather vague about fitment:


Fitment:Currently we recommend these Brake kits for 18" wheels, we are still in the process of testing the 16" rim styles, but with 330mm discs we are confident they will suit most applications, please bare in mind you may need 30mm wheel spacers with 16" wheels!

[twr7cx]

A bit of an update about this space for anyone interested - sadly, other than there is now an additional option available, there is limited progress:


In regards to Dean Lapham's TotalTd5 brake master cylinder upgrade setup that he's been mentioning since at least around November 2020:


L322 master cylinder Was not a thing! It was Late Range Rover sport and not quite finished yet

I could talk you through the conversion but it was late 545 or whatever it is Range Rover master and servo

Dean does also advise that his master cylinder upgrade is not necessary with the bigger brake setups:


I’m running massive 6 pots up front and four pots out back with no issues so far


LOF Clutches does finally have a big brake upgrade kit available for the Discovery 2. Even better is they've changed to Brembo brake callipers rather than the LOF branded ones that early versions were showing (means local support for parts will be easier to achieve within Australia or just from other suppliers).
But the pricing has blown right out. In July 2020 they indicated GBP 600.00 < Log in to Facebook (https://www.facebook.com/LOFClutches/photos/a.161656544524176/582608282428998/) >. In August 2020 this reduced down to GBP 500.00 < Log in to Facebook (https://www.facebook.com/LOFClutches/photos/a.161656544524176/594143547942138/) >. In May 2021 it was increased to GBP 750.00 < Log in to Facebook (https://www.facebook.com/LOFClutches/posts/756310188392139) > And now that it's listed on their website their GBP 1,624.58 < Discovery 2 Front EXTREMEspec Big Brake Kit 330mm - Land Rover Clutches (https://lofclutches.com/shop/brakes/discovery-2-front-extremespec-big-brake-kit-330mm/?v=6cc98ba2045f) > - a huge jump in price!

This makes Dean's front and back kit a lot more price friendly:


The 2200 kit is much cheaper as it uses genuine land rovers discs and not 2 piece discs with bells
This is like the kit pictured
2x large ap four pot calipers front
2x medium ap four pot calipers rear
Brakes lines
Brackets
Bolts
340mm discs 4x

The big bonus here is that the rotors he is using are Land Rover off the shelf, so easy to source. The smaller setup at 340mm is also more likely to fit under a variety of wheels.


LOF Clutches are shipping to Australia:


Shipping to AUS no issue, no tax to pay either

Weight is around 35KG so shipping would be around £145

One friction point is that they have no details available to help you judge fitment of their kit with your wheels. The website ad offers:


Fitment:Currently we recommend these Brake kits for 16″ or bigger wheels

Please bare in mind you may need 30mm wheel spacers due to the size of these big calipers!


E-mailing them about dimensions received:


In truth I am still trialing wheels on the kit, Only thing we could do is get some dimensions of yours and I can try and measure?

It's surprising that they cannot provide any dimensions given they seem to have 3D plastic printed mock setups - Facebook (https://www.facebook.com/LOFClutches/posts/539141156775711)

Which of course is illegal here.

I upgraded my brakes recently, sort of a mini upgrade with new, different rotors all round. That smalll change made a huge, huge difference! as I now brake via my arms as drive with hand controls, so glad for the mini upgrade!

[Slunnie]

I wonder if Dean does the 6/4pot setup over the factory 380/340mm rotors also. This would probably be the same as the factory setup and then we know factory rims for the Brembo set would probably fit.

I'm really surprised they still have not worked out if a standard rim fits these brakes.

[Slunnie]

L322 brakes into the Disco2? Sounds very similar to Dean Laphams, but this may just fit standard 20" L322 type rims which might solve the wheel spacer problems.

Too right , It's moving too fast..... Time to put the brakes on[bighmmm]

Damn!! I gave away my Brembo L322 discs/calipers and 20" rims when I opted for changing discs to L322 petrol V8 discs on my L322 (to fit 18" rims), I could have looked to install them on my D2. aaargghh

The callipers, discs and wheels are the easy part. Designing and fabricating the braket to mount them onto a D2 is still the magic ingredient...

I feel much better now, knowing that I would have had to do some extra engineering if I had tried to fit the discs.
I was surprised if they did just bolt on, but stranger things have happened.

Interested in how these are going and did you go to 17" or 18" wheels to fit them?

I had to remove them back off. There wasn’t enough clearance with the 16” wheels - no touching at static but too close for comfort.
I managed to source a 17” wheel and test it - much better. The issue has been sourcing another five wheels - they were meant to arrive in country mid this month but still haven’t landed.

Where was it close? Was that a rim diameter problem or the spokes?

Did you try the BMW X5 wheel?? Thought they fit and were reasonably available, even if they are not steel which I think you prefer.

I was thinking along similar lines with the D3/4 wheels. The offset is within about 4mm per wheel.

[twr7cx]

Rim.
On a test drive it has some light marks from the inner of the barrel having kissed the brake calipers. There’s clearly a bit of movement so a minimum of at least 3mm of clearance is required.
Stepping up to 17” and no touchy touchy at all.

I’ve looked at BMW wheels previously but I don’t recall the wheel offsets being desirable?
Ideal offset is 31mm. The Dynamic steels come in 30mm which is close enough!
I’m certainly open to alloy wheels over steel. The steels were just because they were the correct specifications and cheap!
Lots of the Disco’s in Euro land seem to run BMW wheels on them.

For a rear brake upgrade option, ICS Motorsport have made an adapter to change the rear brake calipers to the front ones - means you run a larger brake pad and twin piston setup.

I think their original idea is based on reducing the variety of spare parts/components required by allowing you to have a single brake caliper type front and rear.
But it seems like a reasonable companion for the rear after a Brembo front upgrade…

With D2 rear rotors being unvented, I'm assuming theyre early Disco1 front calipers rather than D2 ones?

[ozscott]

Probably no different to what we've done with our pads that have better bite.
If anything it'd enhance it?

The tone rings 'read' the speed difference and the BCU modulates the ABS, with bigger brakes with more bite it shouldn't need to be as aggressive?

On road my TC is pretty seamless, you really don't know is doing it's job in the wet except for the light flashing on the dash.
Very, very different to the new Triton work ute. That just dies in the arse at any hint of wheel slip or sliding with the SC. [emoji56]
Thankfully it has a dash switch. [emoji16][emoji23]


Yep Rick. In high range they combine braking with engine retardation for certain cases of slew and wheel spin (in AWD with Super Select 2 there is more scope for not having engine retardation I have found). Apart from turning off anti slew control in high range, in low range the engine retardation is off completely and the wheel braking only is employed (and is quicker and more advanced as you would expect 20 plus years on from D2. The best of the dual cab utes too. Very effective). I have a set of pads here still from that bloke down the Coast that you put me on to Rick. He made them from the pad composites he made for the 200 series the RAAF Air Defence Guards were running. Will have to put them on with fresh discs as some point. Should be good. Cheers

Nope. Disco 2 front calibers being fitted onto the rear. Along with the Disco 2 front brake disc rotors which means the rear brake disc rotors will now be vented, not solid, and slightly smaller as the front rotor diameter is 297mm and rear 304mm.

Ahhh thanks, thats a better setup!

[admiralranga]

Especially if you've got a spare set of front bits from upgrading those. I'm assuming doing it without upgrading the fronts would only be reducing required spares and that any additional breaking is going to be fairly minimal?

Yeah, I think their original concept was to reduce the spares required and for some extreme users who have fiddle brake setups (I don't know but am assuming this is a brake setup where one has control of the individual brakes or front and rear brake bias).

For most users front brakes do most of the work. Since installing the Brembo's my front components are sitting here not being used so this is a good opportunity to round off the brake upgrade.

On a related note - replaced the hose from the vacuum pump to the brake booster with a new genuine one and it's really increased the braking performance. I suspect that the original had hardened and was leaking off a bit off the brake vacuum resulting in reduced brake boost. It's a good reminder that ensuring everything is working properly at the start is more important than trying to upgrade to better...!
