ABSTRACT:
A motor-driven brake system includes a brake body for enabling brake pads to be pressed against a disk rotor attached to a member which supports a wheel of a vehicle, the brake pads being adapted to be driven by an electric device; a pressing-force maintaining mechanism for maintaining the pressing force generated by the brake body; a pressing-force detecting device adapted to detect the pressing force generated by the brake body; and a control device for controlling the electric device and the pressing-force maintaining mechanism, the control device including an elapsed time measuring device adapted to measure elapsed time during a parking brake operation; and a pressing-force reduction predicting device adapted to predict, based on the elapsed time measured by the elapsed time measuring device and a value of a pressing force, a magnitude of the pressing force generated by the brake body after the elapsed time.
