When Pressure Increases
The control unit closes the cut valve 1 port and opens the suction valve 1 port by supplying current to the cut valve 1 and the suction valve 1. Fluid pressure generated in the master cylinder passes through the suction valve 1 and the fluid pressure is pressurized by the pump. Since power is not applied to the ABS IN valve and the ABS OUT valve, the port of ABS IN valve is open and that of the ABS out valve is closed. This enables the supply of intensified fluid pressure to the front RH caliper.
