Normal braking (ABS not activated)
When the ABS is not activated, port D “11” of the solenoid valve is closed because a control signal has
not been transmitted from the ABS ECU and port A “7” and port B “9” of the flow control valve are open.
Therefore, when the brake lever is squeezed, the hydraulic pressure in the brake master cylinder in-
creases and the brake fluid is sent to the brake caliper via port A and port B.
At this time, the inlet and outlet check valves of the hydraulic pump are closed, preventing the brake
fluid from flowing through the pump. As a result, the brake master cylinder directly pressurizes the brake
caliper during normal braking. When the brake lever is released, the brake fluid in the brake caliper re-
turns to the brake master cylinder via port A and port B.
