Brake pads use metal backing plates with friction-improving material on its face, and press against your brake rotors to slow and stop your vehicle. Your brake pads and rotors are compressed by the brake caliper when it receives hydraulic pressure sent from the master cylinder. With heat from normal use and friction, failure of other brake system components, environmental conditions, and general wear and tear, brake pads will wear down over time. It's important to pay attention to the brake pad's wear patterns and any noises that could indicate failure to keep your brakes performing as they should. If the brake pads are squealing or grinding, they may have worn down to the backing plate, which can also cause damage to the rotor. Brake pads that wear unevenly may indicate a problem with your brake caliper or guide pins. When your brake pads need to be replaced, you may notice your car shaking or pulsing when you brake. This may also be caused by a warped rotor, so it's best to resurface the brake rotor or replace both brake pads and rotors when you complete a brake job.
