Parts Needed To Use Roadmaster Brakemaster Air Cylinder In New Vehicle and Motorhome

Question:

Just got a new tow car, installed direct connect base plate as our MH has a Falcon tow bar. Our old car used a breakbuddy system but this car requires a battery disconnect so no 12v. A friend gave me a Roadmaster 9000 as our coach has air brakes. All I have is the piston and universal floor mount. What parts do I need to install this syatem 2019 Lincoln natulis

If you want to use the Roadmaster Brakemaster cylinder part # RM-9100-50 that your friend gave you I have listed the parts below that you will need to use it in the Lincoln. I highly recommend to use the custom seat adapter because if not you will need to drill holes through the floor board of your brand new Lincoln if you use the Universal Floor mount your friend gave you. The stop light switch is needed in the Lincoln to protect the system just in the case that something with the braking system goes wrong it will alert you.

RoadMaster Second Vehicle Kit with BreakAway for BrakeMaster Systems part # RM-98160
Roadmaster Stop Light Switch Kit part # RM-751475
RoadMaster BrakeMaster Second RV Kit for Air or Air-Over Hydraulic Brakes part # RM-98200
Roadmaster BrakeMaster Custom Seat Adapter part # RM-88317

If you still have the Brake Buddy system like part # HM39494 it should have came with a wiring harness that attaches straight to the vehicle's battery. You can still use this with the battery disconnected from the vehicle but you would want to use a charge line kit part # RM-156-25 from the motor homes battery to the vehicles battery to trickle charge it while your'e traveling so the battery doesn't drain and the brakes stop working. If you still have the Brake Buddy then this would be the easiest way to go instead of the Brakemaster.

If you have a version of the Brake Buddy that plugs into a 12V outlet, you can use 12 Volt Outlet Kit part # RM-9332 straight to the vehicle's disconnected battery and use the charge line I recommended to keep it charged.
