ABSTRACT:
An electric brake device includes a disc rotor which is rotatable together with a wheel of an automotive vehicle. An output rod is provided to press a friction pad onto the disc rotor so as to exert a braking force on the wheel. A brake motor is provided to generate a rotating force in response to an electric signal. A gear mechanism is provided to axially move the output rod relative to the disc rotor in accordance with the rotating force, such that the output rod is moved toward the disc rotor when the brake motor rotates in a forward direction, and the output rod is separated from the disc rotor when the brake motor rotates in a reverse direction. A load detection unit detects a load acting on an end of the output rod opposite to a position where the output rod presses the friction pad onto the disc rotor. A motor deceleration unit decreases the rate of rotation of the brake motor when the load detected by the load detection unit is above a reference level.
