W h e n the wheel speed drops sharply below the vehicle speed, the outlet valve opens m o m e n t a r i l y to reduce the
caliper fluid pressure. The p u m p m o t o r starts at this t i m e . As the wheel speed is restored, the inlet valve opens
m o m e n t a r i l y to increase the caliper f l u i d pressure.
