A brake is a device by means of which artificial frictional resistance is applied to moving machine member, in order to stop the motion of a machine. Braking is a process which converts the kinetic energy of the vehicle into mechanical energy which must be dissipated in the form of heat. The disc brake is a device for deaccelerating or stopping the rotation of a wheel. Aircraft brake disc usually made of aluminium metal matrix composites or ceramic composites, is connected to the wheel. Friction material in the form of brake pads (mounted on a device called a brake caliper) is forced...
