Squeeeelz when I brake

[flex]

Hi guys and gals,

need some help with my line Lately, when I've been driving, I get a sharp squeeling sound when I brake. I would need to brake it hard, for the squeeling sound to stop. Anybody know whats wrong, and how it can be fixed? Maybe, use some grease or something? :Paranoid:

Thanks, any feedbacks would be sweet!

grease??....lol wat pads are u running? have u changed them lately? certain pads squeel when u dont brake hard..its their nature. mine does it when i tap on the brakes really lightly but thats about it. i have bendix by the way.

Is it from the left side of your car? mine does that sometimes under heavy braking.

I think it comes from the passenger.

You may find that your pads have not worn evenly (or you may have sanded them back) and when you apply light pressure the full face of the pad isn't touching the rotor so it squeels (this is what I was told by a reputable brake mechanic in sydney). I get a similar noise on very few occassions, if I softly press the pedal I get a gentle squeeze but if I stand on it then it brakes like it should and without squeel.

You may also want to take ur wheel off and make sure the little shims are in place.

on a similar note......sorry for the hijack....my mates 96 rex makes a loud clunk noise from the front passengers side when breakin all the time. this was after he had them changed and machined. i think they left something out when putting it back together. any suggestions on this??

Knowing absolutely nothing at all about cars, could it be his castor rod bushes that have worn out?

My mechanic replaced mine because they were wearing out and asked me if i had noticed a thunk noise when stopping.

[(B1) MR_fanny]

yeah....someone suggested that too. i think its worth lookin into. thanks MRK25T

If it makes that clunk noise after you have just finished turning a series of corners it could be worn/wearing wheel bearings causing the caliper/rotor to move and then when you apply brake pressure it has to push everything back into place.

Where can you get some wheel bearings for a R33?

I get some small clunking when I'm turning and braking at slow speeds, I was thinking it was my caster bushes, it clunks abit when you are going straight and over a few bumps as well.

My brakes don't squeal when I'm going forward but they squeal like a b!tch when I'm going backwards.:Oops:

good one man .. haha ..

my brakes sounds like Cabs.. squeals like crazy (RB74s) but i dont mind as they're great pads ..

I'm using RB74 + DBA4000 Rotors and no squeeling at all.

yeah he did mention that when he turned left the car feels strange like theres some reisitance. ill pass the info on. cheers guys.

RB74's are bendix ultimates rite?? mine dont squeel at all under normal breakin, only under really light breakin and of course reverse...hehe

[benm]

RB74's are NOT Bendix and they are NOT DBA pads they are www.racebrakes.com.au pads. Bendix pads are designed for the daily driven Falcadores where as the RB74's are designed for the performance/track cars.

where do you buy a full set of doubble shims?

[Anquetil]

I put on a new set of Ultimates on mine a few weeks ago, and followed the 'bedding instructions' as per this site somewhere. I also have new wheel bearings.

They squeel under light braking, my old pads never squeeled.

The only difference I noticed between the new and old pads was that the ultimates only had metallic 'wings' on 2 of the 4 pads at the bottom, anyone know what these 'wings' are?

[Cubes]

My stock pads & ultimates looked both the same. 2 of the 4 pads only had metal wings. As do the Maxi-stops I am currently running.

Did you remember to remove the shims from the origional pads & put them on the new?

Its easy to miss especially when the old pads are covered in lots of pad dust.

My ultimates never squeeked. The new el' cheapo Maxi-Stops ($26 an axle) don't feel anywhere near as nice, produce 1/8th the dust & squeel slightly after being pushed hard.

[Edge]

My pads didn't squeal until I had rear camber adjusters put in and the mechanic got the grease on the rear right brake disc. The front right brake now squeals. I think it got overheated having to cope with more braking as a result, probably just need right front machined again.

When I very very lightly touch the brakes the squeal is intermittent as the wheel turns it is only in one spot. Uneven disc? Perhaps carbonite build up? Can you see carbonite build up?

Would it be advisable to try putting some grease into the shims first or go straight for disc machining?

Would the grease on rear right disc wear off or will I need to use some brake cleaner or something to make sure it doesn't come back?

RB74's are very abrasive. 5 times as much I am told to Galver 1105's which stop real well, much better than ultimates.

Utimates are very very dirty and sqeal like a freight train, went deaf for a day due to the noise after 5 hours of driving, and to keep your wheels clean with Ultimates requires washing every day instead of once a week.
