A rotary actuated braking system includes a motor driven shaft that operates two pairs of piston pumps and an allocation valve which, in combination with a single solenoid valve, effects ABS operation of the braking system. A combination of pressure operated control valves and pressure operated release valves for each control wheel brake respond to operation of the rotary actuator and solenoid valve to effect ABS pressure release and reapply from the corresponding wheel brake. A power boosted master cylinder provides base brake operation independent of the rotary actuator effected ABS operation.

[ What is claimed is:] [1.] A rotary actuated braking system comprising:a rotary actuator including a housing having a longitudinal bore carrying a driven shaft with an eccentric segment, an undercut segment and localized flat segment, the housing also carrying a piston engaging the eccentric segment of the driven shaft wherein the housing includes a solenoid port opening to the longitudinal bore at the undercut segment of the driven shaft, a first valve port opening to the longitudinal bore at the piston and a second valve port opening to the longitudinal bore at the localized flat segment of the driven shaft.
