Guys, my brakes are squeaking when I stop. I think it's one of the front brakes. The thing is I only have 8K miles on the car so I wouldn't think the pads are bad. Have any of you guys had the horrible brake squeak? You think it's my brake pad could it be something else? :eek:

Thanks for the help!

Mine squeek a little when I'm stuck in city traffic (IE light pressure) or when I'm backing up and they are cold. I wouldn't say it is even close to being horrible though.

I'm about 8k miles as well and get an occassional squeak. I wouldn't say it's horrible though either.

Mine squeak like the dickens, @ 20k I have the pads checked for wear (had ~80% left), had just bought new (Hawk Street) pads in case they were dead (figured I was hearing the sensors). Couldn't convince myself to throw out 80% life of the stockers, so I live with it.

I had mine checked too for sqeaking at around 17k miles. They cleaned them but said it would return And it did. So i have to live with it. I also hear it under light braking.

I found this sugestion regarding squeaking brakes, might be worth a try.

Burnishing the brake pads will help to reduce squeals and improve braking performance. Burnishing involves heating the pads to a high temperature to burn off the glaze on them and seat them to the rotor. This is done by driving the car to a speed of about 70 to 80 kph and then braking to a stop with medium to firm brake force. Repeat the stop about ten times, allowing a full one-minute cooling off period in between stops to avoid overheating the brakes.

Mine squeeked pretty loud almost all the time about 1800-2000 miles ago. Now I don't hear them much and I don't know why. I just may have to try to glaze them bitches to make it go away, I hope. My squeeking was quite loud and embarrasing as well.

I had thought about burnishing...but I am afraid that I will warp the rotors. I'd rather have some squeaking than a pulsating pedal. Anbody have this problem?

(and, as I recall a few months ago or more someone (Dreamin? Benjet?) had posted detailed burnishing instructions from some racing source.....)

Same here. I have 24,000 miles now and mine are squeaking like a biatch. James and I looked at them when the new rotors went on and there is plenty of meat left on all four. I will try burnishing them tomorrow. Burnishing sounds fun! :thumbsup:

In better than 90% of all cases; front end brake "squeal" rears it's ugly head due to the failure of the vehicle operator to do two important things:

First is properly bedding/seasoning the new brake rotor discs
Secondly is properly deglazing the new brake pads.

All "NEW" vehicle come with "NEW" brake rotor discs and "NEW" brake pads.

In most cases; the new OEM brake rotor discs (and that includes the OEM gravity cast iron Brembo rotors) are NOT directionally surfaced by the manufacturer which further enhances the build up of brake glaze on the rotors surface which contributes to the squealing noise and what may feel like vibration in the front end of your CTSV under high speed steering or hard braking.

Later this evening, when time permits, I will explain how to properly bed new brake rotors and how to deglaze new brake pads from the beginning as if the car was new.

I will also explain what process you must go through to rid yourself of the problem that you now have ( front end squealing and possible vibration); which is a direct result of failing to properly bed the rotors and deglaze the new pads when the vehicle was virtually new.

Installing a new set of brake pads WILL NOT make the problem of squealing go away. You will have to have your 4 brake rotors removed from the vehicle and "turned" on a brake lathe to remove the uneven build up of brake pad glaze that now exists on your brake rotors. You can't see it in most cases with the naked human eye.

Secondly, the existing brake pads should be inspected to make sure that there is no uneven wear on the leading edges. If there is not and they are still serviceable; I will advise you to retain those pads and will instruct you on how to properly bed the rotors and deglaze those exisiting pads, before installing any new pads for performance or whatever your driving habits may be.

If you must replace the pads or intend to replace the pads based on your driving habits; I'll instruct you on how to properly deglaze those new brake pads on your bedded rotors once they have been directionally surfaced or turned.

In a sense; you will be starting over with a "clean slate" with your brake rotor discs. There is nothing wrong with your brake rotor discs or brake pads. They are not warped, nor are the pads faulty. You simply did not "break-in" the braking system when the vehicle was virtually bad new.

Everytime you now brake, your brake pad squealing is coming from the pads "clamping down" onto material mass that has improperly built up on the brake rotors.

It's kind of like having a small pebble in your shoe. It's tiny and the moment you throw the pebble out....comfort returns. You don't throw away the shoes! You get rid of the damn pebble that feels like a boulder in your Nike's!

I asked the "brake" forum on the old ls1tech.com (now they are different and I can't even log on) and they mentioned that that race brakes that we have don't heat up enough during regular city driving. I'm telling you this car is not made to go slow. My dad used to have an old Ford ranger that I learned to drive manual on, anyway he always let go of the gas way down the road when he knew he would have to stop. I do the same thing. I slowly depress on the brake, and creep up to a light. Again referring to my questions on LS1 and they said that the brakes are meant for the track where youu would depress harder then I usually do. I believe this- when I press hard or (one time) slammed on the brakes I hear nothing. I used to do alot of down shifting to avoid wear on my brakes untill it dawned on me that I'm wearing down the engine, trans, rear, etc. the brakes are easily fixable. Along with others the last time I washed the car I checked the amount of pad/ rotor left and there is silly amounts left for approaching 1 year 20,000 miles. Who ever said it when you do all that burnishing and what not, it comes back so why bother?

All brakes squeak! Its when they hit a frequency that you can hear, that it becomes annoying. They put shims on the back of the pads to pampen/change the frequency. Make sure that you have the shims. Short of that, the rotor has to be orbitally deglazed, or recut like Pete says. Anything that can be redone to decrease 'tracking' of the pad will help. If you are running race pads , good luck, they squeak the most.

Same problem here. Started at around 3K miles, now have 8K. Dealer and parts store guys tell me the same thing. Accumulated brake dust. Wash them hard at car wash or spray some brake kleen on rotors (don't get on rims) and drive immediately as BK will evaporate. Haven't tried either one yet. Dealer had removed the original offender (left rear) and cleaned, but squeaking came back soon. I believe part of the problem is by far the majority of my driving is around town, with no high speed or hard braking, allowing brake dust to accumulate. Would be nice to hear of some improved pads.:annoyed:
