Hydraulic Pressure Circuit when ABS is Not Operating

The hydraulic pressure in the master cylinder increases through the vacuum booster and it is delivered to the wheel via
the normal open inlet valve. At this moment, the normally-closed outlet valve is closed. The speed of the wheel that
hydraulic pressure is delivered reduces gradually .

As hydraulic pressure on each wheel increases, the wheel tends to lock. In order to prevent the wheel from locking, the
hydraulic valve modulator operates the inlet valve control solenoid to close the inlet valve and stop the hydraulic pressure
increases. At this moment, the outlet valve is closed. This procedure helps the wheel to maintain a stable hydraulic
pressure.
