A friction member driven by a motor is pressed against a rotating element that rotates integrally with a wheel to give a pressing force to the rotating element, thereby applying braking force to the wheel. Control means controls the control circuit that controls the motor. In order to apply braking force to the wheel, the control means commands the control circuit to drive the motor once or a plurality of times at a predetermined time interval. Determining means determines a temperature of the friction member at the time when the parking brake starts braking the wheel. Setting means sets at least one of the number of driving of the motor, the time interval, and the target value of the pressing force. Therefore, a steady braking force with high efficiency is generated.

A hydraulic brake lever includes a body having a bladder chamber, a cavity and a flexible separator mounted between the bladder chamber and the cavity. The flexible separator holds hydraulic oil in a front section of the body and prevents a rear section of the body from contacting with the pressurized hydraulic oil. A cylinder is mounted in the cavity of the body and accommodates a piston set. Thus, a high pressure is kept in the cylinder and is not applied directly on the body. Due to the separating design, the hydraulic oil applied a low pressure on the body. Thus, manufacturing the body is less limited and a manufacturing cost is reduced.
