(2) ABS Circuit Per ABS Operation Range
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
▶ No Hydraulic Pressure Circuit when ABS is Operating
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.
