Patent number: 7559412Abstract: In a disc brake apparatus, by means of an actuator which operates in accordance with an operation force, a braking piston fitted into a cylinder portion of a caliper is axially driven so as to push a pad toward a disc rotor. A friction force in a circumferential direction of the disc rotor between the pad and the disc rotor is taken out as an anchor load, and is converted to a servo load by means of a servomechanism. The servo load is applied to the braking piston. The servomechanism is equipped with a hydraulic mechanism (a pressure-reducing control valve, a pressure-increasing control valve, and a reservoir tank) capable of increasing or decreasing the servo load. An electric controller controls the hydraulic mechanism in accordance with the operation force and the anchor load.Type: GrantFiled: August 18, 2006Date of Patent: July 14, 2009Assignee: Advics Co., Ltd.Inventor: Takashi Murayama
