A safety device for use with two concurrently operable fluid actuated assemblies by means of which one of said assemblies may be operated after the other of said assemblies has been rendered inoperative due to development of a leak in the assembly or the conduit leading thereto. One form of the device for use with pressurized air operated assemblies includes time delay means as part thereof, to prevent actuation of the device by a false signal such as could occur if different sized air cylinders were used on the two brake assemblies. Also, the time delay means prevents the device being actuated by a minor leak in the hose or conduit, which is of not sufficient consequence to prevent the two air actuated assemblies from being operated.
