Explanation: "The disc brake is a device for slowing or stopping the rotation of a wheel. A braking disc, usually of steel, is rigidly connected to the wheel. To stop the wheel, the braking pads are forced mechanically or hydraulically against the disc on both sides. Friction causes the disc and wheel to slow or stop."
