PURPOSE:To prevent absolutely breaking in a brake device at the time of non- braking operation and also obtain anti-lock control at cost in a braking hydraulic control device for a vehicle wherein a linear solenoid is energized with brake operating force to actuate a hydraulic valve and thereby, apply output hydraulic pressure of the hydraulic valve to a braking device through hydraulic pressure transmission means. CONSTITUTION:Normally-open solenoid valves 24FL, 24R, for controlling input- room hydraulic pressure are disposed between an output port 21 of a single hydraulic valve 12 and plural hydraulic pressure transmission means 14FL, 14FR and 14R respectively. And then, normally-closed solenoid valves 25FL, 25FR, 25R for controlling input room hydraulic pressure are disposed between the hydraulic pressure are disposed between the hydraulic pressure transmission means 14FL, 14FR, 14R and a reservoir 7, respectively. A fail-safe valve 61 is disposed between the output port 21 and the reservoir 7, which hares over the continuity state in non-brake operation and the discontinuity state in brake operation which valve movement interlocked with and connected to a brake 1. |
