▶Pressure Decreases in the Circuit when ABS is Operating

Even when the hydraulic pressure on each circuit is stable, the wheel can be locked as the wheel

speed decreases. This is when the ABS ECU detects the wheel speed and the vehicle speed and

gives the optimized braking without locking the wheels. In order to prevent from hydraulic pressure

increases, the inlet valve is closed and the outlet valve is opened. Also, the oil is sent to the low

pressure changer and the wheel speed increases again. The ABS ECU operates the pump to circulate

the oil in the low pressure chamber to the master cylinder. This may make the driver to feel the brake

pedal vibration and some noises.

▶Pressure Increases in the Circuit when ABS is Operating

As the wheel speed increases, the inlet valve opens and the wheel’s pressure increases due to

the master cylinder pressure. The oil in the low pressure chamber circulates to the wheel by the pump

and the wheel speed decreases as the hydraulic pressure at wheel increases. This operation

continues repetitively until there are no signs that the ECU is locking the wheels. When the ABS

hydraulic pressure control takes place, there may be some vibration and noises at the brake pedal.
