How Do Brake Pads Work?

Brake pads have two parts. One is a thick pad material that wears slightly whenever you apply the brakes. The padding usually is made of carbon, semi-metallic, metallic, or ceramic padding affixed to a metal plate.

The brake pad resides inside a brake caliper with one on either side of the caliper. That means you have two brake pads on each wheel. A hydraulically actuated piston inside the brake calipers puts pressure on the brake pads when you apply the brakes. The pressure forces the pads to grip the hardened steel brake rotor running between them. As the pads grip the rotors on all four wheels, your car comes to a safely controlled stop. Those brake pads last about 20,000 miles or so before they wear too thin and need replacement.
