Abstract
A full lining operating brake for a heavy duty vehicle is also provided with a parking or auxiliary brake in the form of a heat storing stack of brake plates within the brake carrier of the operating brake and between the carrier and a sleeve connected to the hub upon which the wheel is mounted. A belleville washer spring stack acts upon the stack of plates through a force multiplier disk and is itself relieved to permit the wheel to rotate by the pneumatic displacement of a tube which draws the spring stack away from the brake plate stack.
