Abstract
An electric brake apparatus can positively prevent a brake motor from being excessively rotated in a reverse direction in which a braking force is cancelled. A determination is made as to whether or not the brake motor is excessively driven in the reverse direction. An operation of the brake motor is stopped when the brake motor is determined to be excessively driven in the reverse direction. Accordingly, a member of the electric brake apparatus moved by the brake motor is prevented from being excessively moved beyond a predetermined position. Thus, a part of the electric brake apparatus is prevented from being damaged due to an excessive movement of the member moved by the brake motor.
