A control valve for use in a dual or split brake system having a shuttle or warning piston movable from a centered position to opposed translated positions to energize a driver-warning lamp in response to a predetermined differential between separate supplied fluid pressures acting thereon. A divider member is provided in the control valve defining a flow passage therethrough for one of the supplied fluid pressures, and a proportioning valve is movable in said flow passage to control the application therethrough of the one supplied fluid pressure. A bypass passage for subjection to the one supplied fluid pressure is also provided in the divider member connected with the flow passage in bypass relation with the proportioning valve, and a valve member is normally urged into engagement with the divider member closing the bypass passage. A lost motion connection is provided between the valve member and the shuttle piston wherein said valve member is moved to a position opening the bypass passage upon the movement of said shuttle piston to one of its translated positions.
