Abstract
Automotive hydraulic pressure brake system with a stroke simulator is proposed which while the electric control system is functioning properly, the supply of hydraulic pressure from a master cylinder is cut off and hydraulic pressure is generated by a power pump. This improves response upon rapid pressure increase while minimizing the increase of pedal stroke and the worsening of the pedal feeling.A bypass is provided to communicate the master cylinder to the wheel cylinders while bypassing an on-off valve to be closed during ordinary braking. A shut-off valve is provided in the bypass and a check valve or a relief valve for allowing only a fluid flow from the master cylinder toward the wheel brake cylinders is provided.
