Noisy disc brakes

It is difficult to diagnose sounds without hearing the sounds, but here are some common causes of brake sounds that occur when the brakes are not applied:

Improper rotor installation - fix by removing the rotor and installing correctly Improper pad installation - fix by removing the pads and installing them correctly Aftermarket parts, particularly pads, that do not fit correctly - fix by installing OEM pads. Stuck caliper slide - fix by cleaning up the slide, the slide bushing, and lubing with anti-seize, wheel bearing grease, or caliper slide grease. Improper wheel installation or torque - fix by removing and reinstalling the wheel and torquing the lug nuts properly Bad wheel cover - fix by installing a new wheel cover.

have you yet been back to the garage that did your brake job to tell them about the problem? and if so, what did they say?

Damaged, improperly greased or misadjusted wheel bearings, most common if you have the older style tapered roller bearings. Ray didn't overlook this, it's merely an expansion of his comment "improper rotor installation."

One other problem - very rare in my experience, is an improperly remachined rotor. Many years ago I had disks turned by an auto parts store that owned their own brake lathe. The lathe's collet was out of true.

I think it was snipped-for-privacy@hotmail.com who stated:

Don't know.

YOU shouldn't have to!

Go back to whomever did your brake job and tell them about the sound (assuming it wasn't there before the job was done). THEY should figure out the problem they caused and fix it . . . .

I should have mentioned that the sound stops when I apply the brakes.
