A brake system for rail cars which contains an air powered fluid system, a device for providing a separate source of brake force, and a manifold connected to the air powered fluid system and the device 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 device for providing a separate source of brake force; but when both the device 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 a device for terminating the pressure from the separate source of brake force.
