If the friction surface of a brake drum or rotor is uneven, when the brakes are applied the brakes may squeak.

Brakes Squeak When Braking

The surfaces of the brake are designed to slow wheels down by adding pressure. If the surfaces are uneven, as pressure is applied, it will be unevenly distributed. This can cause a squeak as the caliper or drum make slightly less contact with one part of the rotor or drum than others.
