PURPOSE:To obtain a differential lock function by providing a valve mechanism for checking a lowering of brake liquid pressure and means for operating the valve mechanism between a master cylinder and a wheel cylinder of a brake liquid pipeline system in a braking device for a car. CONSTITUTION:In a brake liquid pipeline system comprising a master cylinder 3, brake tubes 6R, 6L and wheel cylinders 8R, 8L, there is provided a liquid pressure adjust valve 5, thereby to selectively operate check valve 13R, 13L. Accordingly, a lowering of braking pressure of a driving wheel is checked as occasion demands to keep the braking pressure at a designated value. Thus,a differential lock mechanism can be obtained. |
