Negative pressure is introduced into the front vacuum chamber of the power piston, which is displaceably provided in the shell body via a diaphragm, and atmospheric air is introduced into the rear pressure chamber. A switching valve is connected in the middle of the piping between the pressure chamber or mask cylinder of the brake booster that generates thrust in the power piston and transmits the thrust to an output shaft provided outside the power piston and the wheel brake, The vehicle brake system maintains braking force or automatically generates braking force by a brake booster by switching the switching valve, and when the change in speed of the vehicle wheels is larger than a predetermined value, the switching valve is switched.
A vehicle braking device characterized by disabling operation.
