This simulator has a DD3 brake chamber and is set up to demonstrate the type of air brake system used on buses.

Very useful for showing brake operation after dash valve is released. Note: additional application air pressure gauge.

The unit also comes with key switch, low air buzzer and light. 

All DD3 Assistant simulators are on casters for movability and have color coded air lines for service and emergency air.
