Abstract
An anti-skid brake system to supply brake fluid to first and second wheel brakes of an automobile. There are first and second control valves to receive brake fluid from a master cylinder, and first and second bypass valves to receive the bypass flow from the first and second control valves, respectively. A pump receives the bypass flow from the bypass valves in an anti-lock mode and recirculates the brake fluid in the system. There is a release valve that is responsive to fluid pressure levels of the first and second control valves to selectively connect the first and second control valves to the master cylinder, in a manner that with one of the control valves in its anti-lock mode and the other control valve in its normal operating mode, the pump delivers brake fluid toward the control valve which is isolated by the release valve.
