A parking brake controller () activates an electric actuator () in response to operation of a parking switch () to hold a disc brake () to serve as a parking brake. If a failure (fault) is detected in the parking switch (), the parking brake controller () activates the electric actuator () so as to hold the parking brake automatically upon detecting a condition that presumes the vehicle operator's intent not to drive any longer while the vehicle is at rest.
