Abstract

PURPOSE:To reduce the unavailable stroke of a brake pedal, by providing a small- diameter piston having therein an oil chamber adjacently of a large-diameter piston, and also providing a check valve including a spring in said small-diameter piston. CONSTITUTION:When inlet pressure P is raised to a check valve opening pressure Pc determined by a check valve 6 with a spring 7 which is disposed in a small- diameter piston 2b by means of a plug 4, check valve 6 is opened and an oil chamber A in the small-diameter piston 2b is communicated to an oil chamber B defined partially by a large-diameter piston 2a, so that a force SA(P-Pc)+SBXPc is acted to the pistons 2a, 2b. Here, providing that the sectional area of a master cylinder piston is Sm and the lever ratio of the brake pedal is i, the unavailable stroke of the brake pedal is (SBXDELTAt/Sm)Xi, when the brake gap is DELTAt. Therefore, the unavailable stroke of the pedal can be reduced by the rate of SA-SB in comparison with the arrangement in which only a large-diameter piston 2a is used.
