PURPOSE: A brake system is provided to maximize a restoration braking force by distributing the restoration braking force and brake leg power of a brake system operated actively. CONSTITUTION: A brake is composed of: a pressure controller(100) between a booster master cylinder(S) and a brake caliper(C), the pressure controller(100) consisted of a pressure control valve(110), a switch(121) for controlling the pressure generated from the pressure control valve, a control unit(120), and a motor(130) driven by the controller. Then, the operation of the brake system contains the steps of: a user stepping on a brake pedal; delivering leg power of the pedal through the booster master cylinder(S) to the pressure controller; operating the pressure control valve which is a pressure control device; and operating the control unit according to turning on of the switch to drive the motor and also to distribute a restoration braking force and brake force.
