In accordance with some embodiments, the present disclosure provides A brake system for braking a vehicle using one or both of a main braking system and a redundancy braking system, the brake system comprising: a brake demand detecting unit configured to detect a driver's brake demand; an electronic control unit comprising: a pressure controller configured to control a pressure inside a master cylinder in response to a value detected by the brake demand detecting unit, wherein the internal pressure of the master cylinder is controlled by generating an electrical signal for a first demand current; a motor position controller configured to control a position of a motor by generating an electrical signal for a second demand current; and a current controller configured to control the current of the motor in response to an electrical signal received from one of the motor position controller and the pressure controller; a position detecting unit configured to detect a position of a rotor of the motor; and a pressure detecting unit configured to sense the internal pressure of the master cylinder.
