Abstract:
A disc brake apparatus, in which, at the time of a parking brake release operation, a control unit configured to control driving of an electric motor drives the electric motor so as to cause a piston holding mechanism to stop holding a piston, detects separation of a brake pad from a disk, and then stops driving the electric motor after driving the electric motor by a predetermined amount based on a current value of the electric motor.
