Abstract:
1. A disc brake apparatus comprising: a caliper configured to press brake pads disposed on respective surfaces of a disc by a piston disposed in a hydraulic cylinder; a piston thrust mechanism disposed at the caliper and including a thrust member configured to thrust the piston by an electric motor; a piston holding mechanism configured to hold the thrust piston; and a control unit configured to control driving of the electric motor, wherein the control unit detects that at least one of the brake pads is separated from the disc after driving the electric motor to cause the piston holding mechanism to stop holding the piston, and then stops driving the electric motor after driving the electric motor by a predetermined amount based on an electric current value of the electric motor, wherein the predetermined amount is an integrated value of a detection value based on the electric current value of the electric motor after the control unit detects that at least one of the brake pads is separated from the disc.
