The hydraulic cylinder, the oil tank and the oil pump are mutually connected by pipings(41,42). The piston member is withdrew to the side of the hydraulic cylinder to reach to a brake pedal(1) by up and down reciprocating motions. A sensor(12) for sensing a contact with the brake pedal is mounted at the side of the piston member and electrically coupled with a pump actuator(31) disposed to the oil pump. Accordingly, the pump actuator stops the working of the oil pump by an electrical signal applied from the sensor in contact with the brake pedal.
