A rear wheel-side disc brake is provided with an electric mechanism that converts a rotative force of an electric motor into thrust by using a speed reducer and a rotation-linear motion conversion mechanism and propels (displaces) a piston. The electric motor of the electric mechanism is connected to a parking brake control device and controlled by the parking brake control device. The parking brake control device drives the electric motor to discontinue the maintenance of a braking state and then determines from a running state of a vehicle (for example, whether the vehicle starts moving) whether an abnormality (for example, an idling abnormality due to which the rotative force of the electric motor fails to be transmitted) occurs in the electric mechanism.
