The term 'brake pad' is a component of a vehicle's braking system. It consists of two parts: a DISC and a SHOE. The DISC is a round metal plate that is attached to the wheel hub and rotates with the wheel. The SHOE is a flat piece of rubber or metal that is attached to the DISC and presses against the brake drum when the brakes are applied. The SHOES can also be referred to as brake SHOES or brake pads. Together, the DISC and the SHOE form the brake pad, which helps to slow down and stop the vehicle.
