ABSTRACT:
A method and apparatus for simulating a failure in a heavy vehicle air brake system where a failure initiation switch is connected to a failed system selector switch and both switches are connected to a first valve associated with a primary braking system and a second valve associated with a secondary braking system of a vehicle. The failure initiation switch and the failed system selector switch are used to selectively interrupt a braking signal to either said primary braking system or said secondary braking system.
