ようにして車体の挙動を安定化させることができる。Next, the operation of this embodiment will be described. When only the brake lever 1A of the two brake levers 1A and 1B is operated, the hydraulic pressure output from the master cylinder 2A is applied to the rear wheel brake BR. In addition to acting, it can also be supplied to the pot 12 of the front wheel brake BF. However, the output hydraulic pressure of the master cylinder 2A is detected by the detecting means 14A, and when the detected hydraulic pressure is equal to or lower than the set hydraulic pressure, the normally closed solenoid valve 13 cuts off between the master cylinder 2A and the pot 12 of the front wheel brake BF. Accordingly, the behavior of the vehicle body can be stabilized such that the rear wheel brake BR is operated in advance and the front wheel brake BF is operated later.

することができる。As described above, according to the present invention, finer control can be performed when controlling the brake fluid pressure by anti-lock control or the like, and each brake operation member is operated stepwise. This is easy, and the stepwise operation does not disrupt the hydraulic control of the wheel brakes. Further, power consumption can be reduced and durability of the control valve means can be improved.
