PURPOSE:To improve the responsiveness of antiskid control ever so better, by utilizing accumulated pressure of an accumulator for decompression of braking hydraulic pressure as well. CONSTITUTION:When a lock start of wheels is detected, close-open in a first solenoid valve 15 and open-close in a second solenoid valve 16 take place where by in a control piston 9, hydraulic pressure action is produced in its control liquid chamber 10. A pressure receiving area out of this control liquid chamber 10 is set to be larger than a sectional area of a pressure piston 11 so that the control piston 9 gets moving to the left and first closes a cut valve 8. With this closure, a braking device 5 is intercepted from the side of a master cylinder 4. Then, if movement of the control piston 9 is yet continued, capacity in the whole pressure liquid chamber at the side of the braking device increases so that decompression takes place. |
