Abstract
The closed circuit, pump-back adaptive braking system (10, 110, 210, 310, 410) includes a slave isolation valve mechanism (30, 30', 30', 130, 330, 330') which has a valve member (34, 34', 34', 134, 334, 334') that permits master cylinder (12) generated hydraulic braking pressure to oppose pressure received from the pump (23) of the braking system (10, 110, 210, 310, 410) in order to prevent displacement of the valve member (34, 34', 34', 134, 334, 334') when the pump (23) is not operating. When the pump (23) of the system (10, 110, 210, 310, 410) is operating, the valve member (34, 34', 34', 134, 334, 334') is displaced to isolate substantially the master cylinder (12) from an electrically actuated valve mechanism (40, 40') during operation of the adaptive braking system (10, 110, 210, 310, 410).
