Abstract:
1. A brake apparatus comprising: a braking mechanism including an electric motor which is operable to actuate a pusher adapted to push a brake pad against a disk rotor of a vehicle; a controller operable to control the braking mechanism in response to an operation of a brake pedal, and also operable to control the braking mechanism independently from an operation of the brake pedal; and a first detector operable to detect a condition causing a retraction, which is a movement of the pusher away from the disk rotor, when braking is not in operation, a second detector operable to detect a retraction of the pusher; and wherein the controller controls the electric motor to displace the pusher backward when the second detector detects the retraction of the pusher; wherein, after the pusher is displaced backward, when it is determined that a cause for the retraction is eliminated, the controller causes the pusher to move close to the disk rotor by the electric motor.
