<p>PROBLEM TO BE SOLVED: To provide a vehicle brake device capable of reducing valve working noise.SOLUTION: A vehicle brake system 10 comprises: a master cylinder device 14 and a wheel cylinder 32 for each wheel for generating a brake fluid pressure by operating a brake pedal 12; a suction valve 142 provided between the master cylinder device 14 and the wheel cylinder 32, and for generating a brake force by opening/closing control; and a controller 300 for increasing the brake force by controlling the suction valve 142 if the brake force is equal to or lower than a predetermined value when a vehicle stops. The controller 300 actuates the suction valve 142 by PWM driving at least once if increasing the brake force at a start of actuation.</p> |
