The original and main reason that Air Brake equipped Vehicles have these "Chucks" is to provide a way to Air Up the system for towing. With that in mind the majority will be located up front!
Actually that's only sorta correct...if there is ONE chuck, it's usually up front to ADD air to the system to release the brakes...if there's TWO, one is to air UP the system and the other is to air up other stuff...kinda like an innie and an outie. My innie is up front for the tow truck, the outie is in the bay with the fuel and LP tanks....Dennis
