Title: Hydraulically operated disc brakes for vehicles

Abstract: A disc brake comprises a fluid pressure-operated actuator for urging two pressure plates carrying friction pads to opposite faces of a disc. In the actuator a piston movable in a housing is detachably engaged with a draw-bar which acts on one of the pressure plates, the housing acting directly on the second pressure plate. A seal between the housing and the draw-bar contacts an enlarged portion of the draw-bar. A screw-driver slot is provided to prevent the draw-bar from rotating.
