Disclosed is an electromechanical brake system including a pair of pad plates to which brake pads for pressing a brake disc rotating together with a wheel are attached, a carrier on which the pair of plates are installed, a caliper housing slidably installed on the carrier, a piston installed in the caliper housing to move forward and backward, a power conversion device configured to move the piston forward and backward to press the pair of pad plates toward the disc, an actuator including a motor provided to provide a rotational force to the piston and a reduction device provided to reduce the rotational force of the motor and transmit the reduced rotational force to the power conversion device, and a controller provided to control the motor, wherein the controller is configured to determine whether a braking operation mode and a braking release mode are continuously repeated, determine, when the braking operation mode and the braking release mode are continuously repeated, whether a clamping force between the brake disc and the brake pad is not released after the braking operation mode is changed to the braking release mode depending on brake pedal information and clamping force information, and control the motor to release the clamping force based on the clamping force information when the clamping force is not released after being changed to the braking release mode.
