Abstract
A disc brake apparatus including a disc brake having a parking brake mechanism operated by an electric motor as a drive source to mechanically hold a piston in a braking position even after the hydraulic pressure is released; and a controller for supplying a predetermined amount of hydraulic pressure from a hydraulic control unit to caliper caliper, based on a parking-brake indicating signal from a parking brake switch and for operating the parking brake mechanism. In a case in which a brake pedal is being operated when a parking-brake indicating signal is input, the parking brake mechanism is operated in a state in which a hydraulic pressure in the caliper is at a predetermined pressure, after the operation of the brake pedal is finished, so as to reduce a hydraulic pressure required for a release of a brake pedal.
