Abstract
A hydraulic brake actuating and locking device is provided for applying brakes of a vehicle comprising an elongated brake cylinder having a tubular push rod axially operable therein for actuating the brakes and a hydraulically controlled locking device disposed within the tubular push rod and operable when rendered effective for acting on the inner periphery of the push rod to restrain the push rod against axial movement relative to the brake cylinder. The locking device is selectively actuated in accordance with the movement of a locking wedge within the push rod by a hydraulically operated locking piston.
