thanks in advance.What is this whistling sound from my brakes from?Brake noise is common during the first 500 miles after changing the brakes.

the pads may not be centered -placed accurately --if they are shoes simular situation --whoever placed these pads should look at them again .ok by the way i am looking for a car agapetv@yahoo.com what type of car?What is this whistling sound from my brakes from?They take a while to bed in but Id take it back if it continues %26amp; say its making this sound %26amp; a mate said maybe they hadnt used coppaslip on the back of the brake pads to stop the vibration......just an idea but thats something that usually would work.What is this whistling sound from my brakes from?i've heard of squealing, but never whistling. squealing is an inhearent problem with the new semimetalic brake pads. there is a spray paint like stuff that you spray on the back of new pads (the metal part, not the pad itself) before you install them that has worked good for me. as for whistling, the only thing i can think of is that a dust shield got bent during the brake job. if you got the brake job done at a shop, i would suggest taking it back and have them make it right, since you didn't have this problem before the brake job. i would never let a car leave my garage with any squeals or whistling after doing a brake job. it's just not good business. and if you did the brakes your self, take it apart, try the antisqueal spray (you should be able to find it at most autoparts stores), and make sure the dust plates ane not bent. the dust plates are that flat metal round thing behind the rotors. and as far as them making noise until they break in.....i don't buy it. i've done hundreds of brakes jobs, and they are not right if they make noise anytime!
