An aircraft brake system in which there is a single steel disc that rotates with the wheel and rides between two or more brake pads or brake linings. These pads or linings are mounted in the jaws of a stationary clamp, which is closed under hydraulic pressure. When the brake is applied, the disc is clamped tightly between the linings. This resulting friction between the disc and the lining slows down the aircraft.
