Zusammenfassung:A brake subpump adjuster with a pressure-relief valve comprises a cylinder, a lever, a push rod, an intake valve and a pressure-relief valve. The cylinder has first and second ends and at the first end is disposed a fixed piece. One end of the lever is set at the second end of the cylinder and the other end has a joint. The push-rod movable passes through the cylinder and the handle. At one end of the push-rod is disposed a support piece to press the subpump and at the other end is disposed a handle to rotate the push-rod. The intake valve is disposed on one side of the lever to make the piston move, so as to make the push-rod shift. The pressure-relief valve is set on the other side of the lever for relasing high-pressure gas from the cylinder to pull back the push-rod to the initial position.
