What causes brake noise?
As your brake pads wear, small particles of the pad flake off as dust and remain between your brake pads and your brake rotors. This dust will cause excessive vibration, and can cause slippage, which can cause brake noise. ... Dust from these conditions can also cause vibration, slippage, and brake noise.
