A combined lubrication and brake actuating fluid system for a drive axle, separate from the transmission hydraulic system of the vehicle, which utilizes the differential housing as a reservoir and uses the extreme pressure gear lubricant therein as the operating fluid. A pump distributes the gear lubricant through a pressure balanced spool valve, responsive to a brake pedal controlled pilot pressure valve associated with the transmission hydraulic system having output ports to both the lubricating inlet of the axle assembly and also to the brake actuating input port. |
