Abstract: A system and method are provided for using a pneumatic line as a backup communication channel for first and secondary park brake controllers. In one embodiment, a park brake system is provided comprising a first park brake controller and a second park brake controller. The first park brake controller is configured to selectively alter air pressure in an air line of a vehicle to pneumatically communicate a message to the second park brake controller after a loss of electronic communication with the second park brake controller. Other embodiments are provided.
