A hydraulic system for a motor vehicle having an open center type hydraulic power brake booster, an open center type hydraulic power steering gear, and an adaptive braking system using hydraulically powered brake line pressure modulators. The system includes a control valve receiving flow from an engine driven pump and a drive shaft driven pump delivering appropriate quantities of fluid to the brake booster and steering gear. They also deliver fluid at the correct pressure to the brake line pressure modulators upon receiving a pressure signal from the brake booster. Check valves are provided in the pump discharge lines to prevent backflow through a pump in the event of failure of the pump or its drive mechanism. The system control valve also includes pressure relief valves to limit pressures in the several systems to appropriate levels.
