In disc-brake systems, the brake pads are the friction material the caliper squeezes against the rotating disc, or rotor, to slow the wheel’s rotation and stop the car. In drum brakes, the pads are called shoes. Subject to tremendous friction and heat, brake pads wear down and must be replaced as part of a car’s regular maintenance. How long they last depends both on the car’s design and how it is driven.
