A brake system for rail cars which contains an air powered fluid system, a means for providing a separate source of brake force, and a manifold connected to the air powered fluid system and the means for providing a separate source of brake force; the manifold simultaneously delivers pressurized fluid to two movable cylinders under certain conditions and in response to fluid flow from either the air powered fluid system or the means for providing a separate source of brake force; but when both the means for providing a separate source of brake force and the air powered fluid system are delivering fluid flow to the manifold, the brake system contains means for means for terminating the pressure from the separate source of brake force.
