<p>When the hydraulic pressure of rear wheels reaches a predetermined level (breakpoint brake hydraulic pressure), it is possible to prevent the earlier locking of the rear wheels by suppressing the increase of the rear wheel hydraulic pressure. When a live load is large, the locking hydraulic pressure of the rear wheels becomes higher than this predetermined level. Due to this, it is possible to shorten a stopping distance by increasing the breakpoint brake hydraulic pressure in accordance with the live load. The present invention provides an optimum control of the rear wheel braking through a simple construction using a hydraulic valve installed on a hydraulic pressure flow path between a master cylinder and the rear wheels by altering the value of the breakpoint brake hydraulic pressure by a signal value based on the live load.</p> |
