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.
This heat causes the pad(s) to harden and crystallize, or glaze. Squealing can also be attributed to broken anti-rattle clips (clips that hold the brake pads in place) and/or worn-out brake pad insulation. In any case, it is recommended to have your brakes evaluated as soon as possible if you hear this noise.
