Thread: Brake upgrade for Discovery 2?

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!

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.
Thankfully it has a dash switch.

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.

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?

Dean Lapham < Page not found | Facebook > who seems to be the owner/operator of TotalTd5 < TotalTd5 - Td5 Performance Parts, Automotive, Land Rover Parts >, a general Land Rover Td5 enthusiast making a bunch of his own custom parts etc., and according to Jose (of Td5Inside) he works at JLR full time too, is apparently offering some brake upgrade options:

Saw a comment here the other day about there being no discovery td5 brake kits available! TotalTd5 discovery 2 four pot AP racing brake kit!
This is available with 380mm front discs for 18” wheels or 340mm for 16”

And 340mm rear for both 16” and 18”

These are for my everyday car hence being painted straight out the packet

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.

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
