Brake pads are a component of disc brakes used in automotive and other applications. Brake pads are composed of steel backing plates with friction material bound to the surface that faces the disc brake rotor.
Brake pads provide the friction to slow or stop your vehicle. There’s a lot more to effectively using your car’s braking system than simply stomping on the pedal when a squirrel darts out in front of you.
The most common symptom of bad or failing brake pads are noisy brakes. Brake pads can accumulate dust as they wear, which if allowed to build excessively, may cause vibration and squealing when the pedal is applied or let off.
