Apply trailer brakes automatically during a breakaway or supply-line loss with the Bendix Air Brake Emergency Relay Valve. The valve works as a relay for normal trailer braking and also triggers an emergency application from the trailer reservoir when supply pressure falls. That dual role makes the Bendix 281865N central to how the trailer stops if its air supply is lost. A breakaway test during each inspection confirms the emergency function works.
