PROBLEM TO BE SOLVED: To prevent wheel cylinder pressure being sealed between a wheel cylinder and a master cut valve in a brake fluid control device. SOLUTION: A first master cut valve (SMC-1 )88 and a second master cut valve (SMC-2 90) are arranged between a master cylinder 14 and wheel cylinders 76, 78. The wheel cylinders 76, 78 are connected to a regulator 15 through a separation valve (SS)58 and a pressure increasing linear control valve (SLA)28. The valves (SMC-1 )88 and (SMC-2 )90 are closed, and regulator pressure P is introduced to the wheel cylinders 76, 78 through the valves (SLA) 28 to perform brake controlling. At the time of completion of brake controlling, wheel cylinder pressure PW/ C is released to a regulator 15 through the valves (SS)58 and (SLA)28, and the valves (SMC-1 )88 and (SMC-2 )90 are opened. |
