A brake pedal pressure variation reducing apparatus for a vehicles equipped with an ABS(Anti-Lock Brake System) is provided to decrease variation of brake pedal pressure by employing a high pressure accumulator which discharges pressure of a wheel or supplies pressure of the high pressure accumulator to the wheel. In a brake pedal pressure variation reducing apparatus for a vehicles equipped with an ABS(Anti-Lock Brake System), a master cylinder(10) contacts a USV(Upper Seal Valve,20). A wheel(50) contacts the USV through an EV(30) and an AV(40). A high pressure accumulator(60) contacts the wheel. A low pressure accumulator(80) contacts the high pressure accumulator through a pump(70). When pressure of the wheel reaches a predetermined level, a pressure line of the master cylinder is shut off and pressure of the wheel is discharged to the high pressure accumulator or pressure of the high pressure accumulator is supplied to the wheel. |
