The metal rotor that the brake pads squeeze together can sometimes vibrate, causing a squeaking noise. Luckily, there are several ways to fix this: 1  Use a milk spray, lotion or cream on the back of the pads [source: Allen].  Use sandpaper to sand off surface hardening of the brake pad/shoe surface.
Warped brake rotors are the most common cause of braking vibrations. In addition to a vibration, warped rotors may cause your calipers not to release completely and lead to uneven brake pad wear that will cause your brake pads to need to be replaced sooner than they should.
