<P>PROBLEM TO BE SOLVED: To manufacture a brake system for a vehicle at a low manufacturing cost. <P>SOLUTION: In a cylinder (81), an input piston (82) and a pressure piston (83) are supported movably along a shaft direction, a portion of the input piston (82) is fitted to the pressure piston (83), and a brake pedal (14) is connected to the input piston (82). Control hydraulic pressure becomes suppliable to a first supply port (93) of a second pressure chamber (R12) and working oil in a first pressure chamber (R11) becomes dischargeable from a discharge port (96) via a through-hole (92) and a fourth pressure chamber (R14) while the control hydraulic pressure is made dischargeable from discharge ports (94, 95) of second and third pressure chambers (R12, R13). <P>COPYRIGHT: (C)2012,JPO&INPIT |
