Abstract
During an operation of applying a parking brake, when sufficient brake clamping force is applied by a brake actuator, a parking lock actuator having a pin is energized to cause the pin to be moved toward a strut so that the strut is engaged with one of notches of a rotatable part operably connected with the brake actuator in order to prevent rotation of the rotatable part in one direction of releasing the brake and to allow rotation of the rotatable part in the other direction of applying the brake, and then the parking lock actuator is de-energized and the pin is moved away from the strut. During an operation of releasing the parking brake, the brake actuator rotates the rotatable part in the brake apply direction to disengage the strut from the notch, and then releases the brake.
