Abstract:
A lock piston operates to automatically lock a parking brake piston which achieves a parking brake applied state in response to hydraulic pressure in a parking brake application control hydraulic chamber and operates to release a locked state in response to hydraulic pressure in a parking brake release control hydraulic chamber, and a manual change-over unit holding the hydraulic pressure in the parking brake release control hydraulic chamber to a hydraulic pressure on a lock release side, is provided among the wheel brake side hydraulic path, the parking brake application control hydraulic chamber and the parking brake release control hydraulic chamber by bypassing a hydraulic pressure control unit which changes over the application or release of hydraulic pressure to the parking brake application control hydraulic chamber and the parking brake release control hydraulic chamber.
