Modern brake pads often contain wear indicators that create a high-pitched squeal when the friction material becomes thin. This warning is intended to encourage inspection before more expensive damage occurs.

However, worn pads are not the only cause. Dust build-up, glazed brake surfaces, moisture and rotor wear can all contribute to brake noise. Determining the exact cause requires a professional inspection of the entire braking system.

Ignoring brake noise can allow a minor issue to become a more costly repair. A vehicle that starts with worn brake pads can eventually require rotor replacement if left unchecked.
