Even when the hydraulic pressure on each circuit is constant, the wheel can be locked as the
wheel speed decreases. This is when the ABS HECU detects the wheel speed and the vehicle
speed and gives the optimized braking without locking the wheels. In order to prevent the
hydraulic pressure from increasing, the inlet valve will be closed, the outlet valve will be opened
and the oil will flow into the low pressure chamber. In addition, the ABS HECU 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.
