Squeeling 99 GT

[dmontzsta]

My car has new rotors and pads, but for some reason it squeeks, not even when you are on the brakes. If I am coasting or accelerating from 5mph-20mph there is a squeeking coming from them, any idea what would cause this? I am stumped. When they are squeeking, I can tap the brake and it will stop while I am on the brake.

Maybe the rotors or brakes got something on them. Some particles or even grease would make it squeal. Spray some brake clean on the rotors, see if that helps.

my right front wheel just started doing this as well. the pads are still good but the strange thing is it only does it when i turn to the right and it goes away when i touch the brakes

Did you rebuild the calipers? Did you use stock rotors/pads?

my mach does it too, both the fronts. Guys at the local shop said it was common with brakes that have a floating pad. Have done much follow up research yet so everything past "it's pretty common .." is greek to me. Thinking about puting on some of the anti squeek stuff if I can get motivated enough to pull the pads off the front myself.

Depending on which pads you have, it might be a good idea to seat them. Take the car up to about 80 mph and then hammer the brakes. Don't let them lock up. Go down to about 20, then do it again. After 4 or 5 of those, they should stop squealing.

I have that problem with new brakes but I'm using powerslot rotors and SBS race pad. A few stops from 130+mph and they stop squealing.

Holy christ LOL well that sure isn't the "by the book" way on how to correct this problem.

Try taking the pads off, and making sure no grease is on them, and maybe even rough the pads up a little with some sand paper to make sure no grease became inbedded into the pads. Then try greasing up the contact points on the outside of the pad and the caliper piston.

Then check to make sure hte splash shield behind the rotor is not contacting the rotor at all, especially while turning the wheels.

Loud/Squeeky brakes should not be accepted as a "common" problem. The only common thing about it is that some low priced cheap aftermaket brake pads have been known to squeel, but there isn't anything you can do about that except get differnet pads. But good pads should not be making constant noise. Did the car roll off the factory line making brake squeeling down the street? Dont think so

That goes back to my original question, which brakes does he have? Since that was never mentioned, I made an assumption. That is the way you seat Baer brakes and other performance pad combinations. You need to embed some of the rotor material into the pad and that is the process. If they are just stock brakes, then you would be correct.

BTW, the 130+ reference was actually made on the track this week down the straight at Firebird and damned if those brakes didn't quit squealing on the street after that.

well im having the same exact problem with my new baer rear brakes. in right handers the driver side rear is squealing like a mofo. the shop that installed it is telling me that its a spline issue. now im gonna take it in to the mustang specialties shop since they are an authorized baer dealer to make heads or tails of this mess.
