Loud squealing when applying Brakes on my Defender

[Robmacca]

Guys,
My front brakes on my defender have become VERY noisy when I apply my brakes. It's a loud squealling sound. If I apply my brakes hard then there is no squealling. The discs are in good order (no lip) and there is plenty of meat on the pads. I'm not sure of the brand of pads as they were already in there when I bought the car.


Any ideas as to how I might be able to get rid of the squealling when I apply my brakes?

good hose out with the pressure washer to remove dust.

[filcar]

Have you been in a dusty environment lately? Mine squealed like heck on a recent dusty trip through central Aus but are fine now

[vnx205]

Mine only ever squeal when I drive on dusty roads.

Do yours squeal on sealed roads?

[Robmacca]

I haven't driven on Dirt Roads for ages, so, it's been mainly all bitumen driving....
I'll try the hose out idea but don't think it will achieve the right outcome....

[Flexo]

Mine has been like that since buying it over a year ago.

I've read wrong pads can cause it when they have no chamfered edge.

[komaterpillar]

Rob mate, clean the whole show out and then run a bead of high temp rtv silicone along the back of the pad where the caliper pistons contact the pad. Sometimes - not all the time - squealing is caused by the pads vibrating in the caliper under light loads and goes away under harder application. I'd say this is your issue, both my 110 and my wife's Hyundai i30 did it, the silicone on the back of the pads fixed it up.

[vnx205]

I just noticed you said it is your front brakes squealing. If that is the case then my earlier comment is probably irrelevant.

I'm fairly sure it is only my back brakes that squeal on dusty roads. I don't think the front brakes are exposed to dust in the way the back ones are.

[PhilipA]

You can buy a spray can of anti squeal which dries to a plastic material when sprayed on the BACK of the pad.

Squealing is often due to the pads being so hard that they cut through the rubber stuff on the back and it is metal to metal with the caliper piston.

Are you using OEM brakes with the anti-vibration plate thingy......I've only used OEM and never had issues

[Robmacca]

I couldn't tell u if they are OEM or not as they were not the vehicle when I bought it. I had a look and there is not anti-vibration plates either....

Thanks Brett..... I assume u mean either side of where the piston makes contact with the pad & not actually where the piston makes contact?
I've swapped the pads from side to side to see if that changes anything first, then I'll look at your suggestion.

Nah mate i mean where the piston contacts the pad.

You put your bead of silicone on, put the pad back in the caliper, put your foot on the brakes a couple of times to push the pistons back out, this squashes the silicone out from between the pad and piston. All done before the silicone cures. The silicone is only there to prevent movement between the pad and piston - wich presents as squealing brakes.

Ever removed an old set of pads and seen the fret mark on the back side where the piston contacts the pad? This is preventing that fretting

[komaterpillar]

You can also buy proper brake caliper lube for the same job but i prefer the silicone method as the silicone doesnt displace like the lube, its cheaper, and ive normally got an open tube of high temp RTV in the toolbox

The proper stuff:

[steane]

Only way I could fix this on mine was to use genuine LR brake pads and regularly check the wheel bearings. If they loosen up, the brake discs knock the brake pads further apart than normal which lets in more dust/dirt and you get more squealing as a result.

Cool, I might try that then, I assume u don't use too much silicon?.... also I assume it's easy enough to remove the pads in the future when they need replacing?

I obviously don't need that anti-vibration shim/plate at all as I don't have that shim/plate...?

Well, swapping the pads around didn't work, so I'll try Brett's suggestion.....

My MY15 does the same, servicing by LR finds nothing. Only happens once you've been driving for 10 minutes or so and on regular graduated braking. Doesn't occur if you brake hard. I'll look into the solutions suggested here.

I gave the silicon suggestion a go and it has seemed to work but it does still squeal every now and then. Not sure on how much silicon to use, so I used the silicon sparingly and also not sure if I used the correct type of silicon as it's only rated to 270degree in temp. It has definitely helped though, so will how it goes and if need be I'll look into getting the right type of silicon..... Otherwise I'll put in the set of new pads I have sitting in the shed

[Robmacca]

Gents....

I'm still trying to solve my squeaky REAR Brake Pad issue. I've tried a couple of suggestions on here but it only seems to work temporarily & then when u go driving on dirt roads, then it gets worse...

The pads I'm using are the RDA Pads (Orange in colour). I've been told there are other better/more suitable pads so I'm looking for people's experiences & Ideas as to what REAR pads I should be using....

History: I've fitted NEW Discs and Pads but the Pads are way too squeaky for me to handle & I need to do something before our family touring trip....

Ideas??

robTRW pads seem to be a good fix.

Ferodo squeal like banshees too

[Robmacca]

Anybody tried this stuff made by CRC?132217

Curious to know if this stuff will work in quietening the squeaky brakes?

[weeds]

I have found OEM pads to be squeal free......ensuring you install as per instructions.

I assume that's with the Shims and springs for the pins, etc ???

Rough idea of the $$ for OEM pads ??

Yep, no idea what I paid as it was a while ago, I do remember I purchased from MR

[timax]

Im willing to bet your disks are glazed. I put new pads with CRC silicone pad glue in mine and they still squealed.
A sanding disk on my drill fixed the problem.

Yeah already did the sanding disc thing but it only worked temporarily. The discs are still new.
Hoping the CRC might have been a solution, but a different pad might have to the solution in the end

[Robmacca]

Guys,

After some names of different Brand Pads that people used on the rear of their Defenders that they have had success in not having squeaky brakes

What are the brembo brakes like?

[Robmacca]

One last crack at trying to solve the squeaky brakes - I've tried a product called "CRC Disc Brake Quiet". So far its working with the VERY HIGH pitch squeal now gone but I'm yet to go on dusty dirt roads and 4wdriving so time will tell, but all good for the moment....

[timax]

I also use the CRC product and have done for years on many cars.
I love it but have found on my TD5 110 that with Bendix 4x4 pads on a glazed disc it still woke up the whole suburb!

[Robmacca]

Well... back to square 1 again.... Squealing on the REAR brakes is back and I've done the following:

Tried the products mentioned w/o success
Tried a different brand of pads w/o success
Sanded the Discs (both sides) and this fixed the squeal for a period of time but it's coming back again


Things I've noticed:

No squealing of the brakes when I'm in reverse
I've blocked off the rear brake hose temporary to proved that it was coming the rear (which it is)
Squeal only seems to be there once the discs are warmed up (ie: after a period of driving to/from work)


Up for ideas on how to solve this PITA problem?

Softer Brake Pad ?? // New DISC's (again)??

Note: Calipers are not leaking / removed the small light spring that slides over the pins


ideas??

[dromader driver]

I have used Bendix brakes from repco front and rear and don't normally have a squeal.

Try a pad change and ascertain if you can get the new bendix pads. Looks like both their suv and heavy duty pads have the rubber backing to reduce noise.
If the discs are still good try a change and just scuff the disc with glasspaper prior to install. Use a circular motion when rubbing and just do it by hand.

Other option is to regrind the disc face and install new pads.

New pads on old worn discs can be exciting for the first few stops so follow the install directions. [bighmmm]

[travelrover]

Had the same issue on my TD5, could not get rid of the noise, spoke with my independent service guy (Land Rover expert) said replace with genuine pads, which I did and problem gone. Now have exactly the same problem on my 300Tdi, new rotors and pads which were supposed to be genuine but appears they are not. Problem is only there on light to medium braking, heavy application of the pedal no problem. Looking like I need to change these for genuine but as this is my project vehicle not a priority just now.

[vnx205]

My Defender brakes never squeal if I have not been on a dusty road.
They always squeal if I have been on a dusty road.

Where do u source your genuine LR Pads from ??? Paddocks??

Through my indy service guy. Been going to the same place for over 30 years! I have only had a problem when I have gone to another mechanic due to proximity , I live 90km from my Landy guy.

[Dorian]

MR will only sell me genuine pads. I'm sure they will have them in stock.

Cheers Glen

[Robmacca]

Just curious here.... but if your Discs are "Glazed", is this a indication that the PADS are TOO HARD or is it a indication of something else?

If it is a indication of Pads, then would a "softer" pad be the go then and if so, do they actually make softer Disc Pads?

[Mick_Marsh]

Discs?

I used anti squeal shims on my rear breaks. Fixed the problem.

My rear brakes squeal on light use since the rotors and pads were done recently. I'm ignoring it.

[Robmacca]

A set of Pads I've tried already had shims on them and that didn't solve the issue.....

Likely pads are too hard or If the brake rotors are like polished metal or grooves in them or have a lip on them, throw them and the pads over your shoulder.

Bendix, Delphi, eurospares, any decent brand in both pads and rotors and all will be good.
They dont have to be genuine, in fact the last genuine pads I had to get were for the latest **** Range Rover Sport and cost the debt of a small country as nobody else did them.

P.S flush your brake fluid while you are doing the big brake job.... every 2 years or so.

Daz

[Robmacca]

Cheers for that.... I've come to also believe that the pads are too hard but finding this sort of info on the the hardness of pads is very difficult....

Replaced the Discs and Pads (BRand: RDA which is Rotor Disc Australia) about 9000k ago and flushed the brake fluid as well I think.... and that was back in Apr'17. Been chasing this squeaky brake issue for the past 3>6mths or maybe longer, I've lost track....

Going to ring MR tomorrow and get their thoughts and also visit the local Brake specialist and query about on car Disc machining......

Got to get this sorted as it is not making driving the Defender enjoyable atm... :(

ohhhhh RDA you say??? thats why your brakes are squealing like a stuffed pig.
Are you using the **** gold pads or the **** orange pads? both are crap.

Change the pads out for some bendix and hopefully they will be ok.

Ha, yes I've already changed Pads out for a set of Brembo Pads and to be honest, they are no better, if not worst..... I've been warned off Bendix Pads as they are a hard pad as well & will be just as noisy....

[dero]

+ 1 on the TRW pads , they are the only solution I have found .
I have heard that the genuine pads are good too .

[Robmacca]

It certainly seems like a Disc Glazing issue.... but how or what causes your Discs to Glaze up ?

[Robmacca]

Well..... I bit the bullet and bought new Bosch Disc Rotors and OEM Pads and fitted them and I'm happy to say to date that the squealing has gone..... but it is still early days, so I'll be happy once I've hit the dirt tracks and come away still will no squealing brakes.... :)

[martnH]

Mine squeal a lot before. My wife can not stand the noise but I am okay with it.
The squeal will alert ppl driving around me that my braking is probably a bit iffy

Then after 4 months the squeal is gone forever
Now I miss it

[200defenda]

Yea i have the same problem on the back right side squealing badly. Replaced rear rotors RDA brand, and brake pads delphi. New springs and pins. And almost straight away the squealing is back again. Might have to try genuine pads.

[steveG]

I haven't read the whole thread, so maybe its already been covered, but...
FWIW, a few years back on my 130 I replaced the rear pads with some Mintex from UK (which I've had good experience with on my County).
They squealed badly from initial install. Pulled the anti-squeal shims off the old pads and fitted them to the new ones.
Squeal gone instantly, and hasn't returned.

SteveYes this is very important too.

The aftermarket brake pad usually comes with shims. And what I did is remove the aftermarket shim and put on factory anti-squeal shim.

Sometimes the shim is glued on pretty good and I just rip it out

The factory anti-squeal shim has a present shape cutout in the middle

[200defenda]

Looking online i cant seem to find any anti squeal shims which you can purchase seperate. Looking at genuine pads kits they come with metal shims.

Through my efforts to stop the squealing, I've left aftermarket shims in; then tried removing them and using some of the anti-squeal products that are out there all with no success...

Last resort I forked out the money for new bosch rotors + OEM Pads that come with new pins/shims. After fitting them and test driving all was good until I went through some dirt tracks where the squeal has come back "slightly". back on the black top I still can get them to squeal but it is nowhere as bad or as often as it was previously.... I'm kinda hoping that our drive down to the VHC will see them bedding in better and the squeal disappearing totally.... well, I'm praying for that at least :)
