System will not activate from RV.
Check the ground between vehicles. The system uses only 1/2 amp to activate and the lighting ground between the
vehicles may not be good enough for the Vac Brake system to get ground. A better ground from the Vac Brake may be
needed closer to the lighting ground wire between the vehicles.
System will not release from RV.
Check for a 12VDC backfeed to the activation wire on the solenoid. Isolate and add diode or change wiring to eliminate the
12VDC backfeed condition. Pulling apart the wire harness between the vehicles should release the Vac Brake. Also check
to be sure the breakaway switch is not triggering the system.
Feedback light on RV dash does not light.
Make sure all connections between vehicles are correctly made between corresponding terminals at the wiring plugs on
vehicles. Test for power feed along all wiring between vehicles.
System will not pull pedal and stop satisfactorily.
Check vacuum level in system during operation with a vacuum gauge. You will need 18"-20" for the brake to
work. Check for vacuum leaks by shutting down engine with gauge on and see if vacuum holds. Levering down
the pedal can compensate for lower vacuum level and make stopping force stronger. Check to be sure there
are no sharp turns on the cable housing between the pedal and device.
*Note this system can only deliver braking as good as is provided by the vehicle. If fluids in brake system have not been serviced
every two years as recommended, it may effect final performance.
