Disclosed are an electronic caliper brake and an operation method thereof. The electronic caliper brake includes a carrier on which a pair of pad plates are installed to advance and retreat, a caliper housing slidably installed on the carrier and provided with a cylinder in which a piston is installed to advance and retreat by a braking hydraulic pressure, a hydraulic pressure supply device configured to supply the braking hydraulic pressure to the cylinder, a spindle member installed to penetrate through a rear portion of the cylinder and configured to rotate by receiving a rotational force of an actuator, a nut member configured to advance and retreat depending to the rotation of the spindle member to press and release the piston, and a power transmission device in which an input part is connected to an output shaft of the actuator and an output part is connected to the spindle member, and configured to transmit the rotational force of the actuator to the spindle member.

An electromechanical brake system having a suspension control function. The electromechanical brake system includes: an electromechanical brake connected to each wheel of a vehicle to brake the vehicle, a suspension configured to control suspension of the vehicle, a motor configured to provide driving force to the electromechanical brake or to the suspension, a first clutch configured to connect the electromechanical brake and the motor to each other, a second clutch configured to connect the suspension and the motor to each other, and a controller configured to output a control signal for controlling the motor to be connected to one of the first clutch and the second clutch based on a state signal of the vehicle.
