GT3 Squeaking Brakes - Solution.

[Randompunter74]

So, took my car in for a full service, cleaned up discs (As I did the silly thing of cleaning it and not driving it. Then small bit of rust formed on the disc between the pad and the rear discs causing slight vibration. Anyway sorted that. Skimmed the rear discs a little) - Note, I have standard pads

Main thing is, squeaking front brakes. There has always been much debate about this and I have to say...it pisses me right off.

So, can anyone give me an absolute certain line on how to remedy...all of some of the below.
- The Material of the Pads. Many say its the brake pad material (I believe it is with race pads, but not the standard GT3 pads)
- Chamfer the leading edge of the pad (I did this on my old Vanquish and it worked some time back)

What I would usually have done back in the day:
- Coppa slip the pins and back of the pads. I am pretty sure this used to work a treat. (Although these days, especially in Dubai, they dont do this)
- Skimming the dics. (I hate it when firms out here seem to this this is the resolution to everything to do with pads. It shortens the disc life and I don't believe it works)

Appreciate any thoughts and suggestions which you know for certain remedy this. Nothing looks more crap than pulling up and having squeaking brakes like some old transit van.



Cheers

"Note, I have standard pads "

"I believe it is with race pads, not the standard GT3 pads"

come back and tell us which pads you have !!!

most people nanny the brakes and glaze them what ever pad is in it.

I have standard brake pads and I drive the car like its stolen, 3 times a week.

I meant to say, I know that some of the Race Pads can squeak....but standard ones shouldnt should they?

Together with giving the brakes a really good work out to remove any pad deposits, get yourself some of this and smear it onto the back of the pads.

I find it's more the Spring bar so put ceratec on the contact points on the pad spring thing and where the bar goes though the back also.
I run RS29 and get no noise and don't coat the back of the pad.

I don't actually get any noise from mine either, but am sharing my experience from my very noisy PF 01's which are fitted to my track Evo.

Mine squeal and it's annoying especially at low speeds, I think I need to give it a real hard work out and see how it goes from there

All I can offer is what I have found works to eliminate, for a while, squealing from both my Boxster and my Turbo's brakes.

Wash the brakes.

At a DIY car wash I set the wash nozzle to soap and sprays the wheels/brake hardware throughly. I do *not* jam wash nozzle too close to the calipers and the pads/pistons.

Then switch to rinse and thoroughly rinse the soap away.

Save some time to switch to the no spot rinse setting and throughly rinse the wheels/brake hardware again.

Where I do this the water force is quite reduced in no spot rinse setting so I get the tip of the wash nozzle closer to the caliper to try to rinse the brake dust from the piston dust boots.

After this I take the car out and use the brakes often enough, and hard enough, to throughly dry them of any water.

If you fail to do this the brakes will rust something fierce and create other problems.

Caution: The brakes will not have much if any initial grip so use the brakes some as soon as you can to eliminate the temporary condition.

Afterwards the squeal that was present when using the brakes lightly is gone. It will come back though after some months of driving as the dust builds up on the dust boots.

Pretty much all the suggestions are fixes to varying degrees but no two brake systems perform the same modally so different parts of the brake will resonate and cause the squeal in different circumstances. Your best bet will be to make sure the discs, calipers, pads and shims are all in good clean condition and any parts that should have grease also have the correct type.
