Disc brakes utilize a pinching action on a metal disc, which is often referred to as a rotor, to slow or stop tire rotation. When the brake pedal is pressed, brake pads clamp down onto the rotor. This friction created by the pads pinching the rotor is what effectively slows down the wheel's rotation, allowing the vehicle to decelerate or come to a complete stop.

In contrast, drum brakes work by forcing shoes against the inside of a cylindrical drum, which is a different mechanism. Parking brakes are designed to hold the vehicle stationary and are often based on either drum or disc systems, but primarily serve a different function than standard braking. Power brakes enhance braking force using hydraulic assistance but do not describe the method of slowing the vehicle itself.
