Patent ID: 8812210

Claim:
A vehicle brake system, comprising: an input device which receives an operator's brake operation; an electric brake actuator which generates a brake hydraulic pressure based on an electric signal according to at least the brake operation; and a vehicle behavior-stabilizing device which assists vehicle behavior stabilization based on the brake hydraulic pressure generated in the electric brake actuator, wherein the input device, the electric brake actuator, and the vehicle behavior stabilizing device are separately disposed from one another in a room for structures, the room being partitioned in front of a dashboard; and the input device comprises a housing including: a master cylinder which generates a hydraulic pressure according to an input through operation of a brake operator, the master cylinder extending in a front-rear direction of a vehicle; and a stroke simulator giving a brake operator a simulated operation reaction force, the stroke simulator being disposed in parallel to and in communication with the master cylinder, so that the stroke simulator and the master cylinder are integrated, wherein bosses are formed beforehand at a plurality of locations in the housing; a port can be produced in the boss at any of the locations; and the port is formed to project forward of the input device.
