Hey everyone, Shane here, with etrailor.com. Today, I have a 2021 Jeep Gladiator. I'm gonna walk you how to install Demco's Air Force One, supplemental braking system Second Vehicle Kit. The Air Force One is gonna be designed for motorhomes with air brakes. It's gonna be a truly proportional system. So, when you compare it to some of the other systems, like the Demco Stay-IN-Play DUO that work off of a signal coming from the light, this one is actually working off of air pressure coming from the brakes on the motor home.
What it does is when you apply the brakes on the motorhome, it sends air pressure through this line, into the system, and to an actuator mount on the brake pedal arm. So, it's gonna match the amount of pressure that you're applying in the motorhome. The braking system is gonna be one of the five main components needed to flat tow the Gladiator. The other four are gonna be your base plate, which attaches to the chassis of the vehicle to give you that solid connection point for your tow bar. Your tow bar, which gives you that connection point between your base plate and your motor home.
Your safety cables, which act as a secondary safety device, and your wiring. Your wiring is gonna be designed to allow the vehicle, while it's being flat towed, to receive light functions from the motorhome, whether that's braking, turning, or driving at night, so that everybody around you knows what you're doing. Now, if we're not flat towing the vehicle, or we want to disconnect, we're gonna take our air line, fitting right here, we're gonna pull back on it. That's gonna disconnect it. Our kit is gonna come with a cap.
That's gonna cover that hole, so we don't have any dirt and debris that gets clogged in there. We're also gonna have one for the motorhome side. when connecting to your air fittings, when connecting your line to your fittings, you want to make sure when you push it on, push it on and give it a little tug. That way you know it's not gonna come disconnected. You're gonna have a actuator that mounts to the brake pedal arm in the towed vehicle.
Can you see the airline tube that runs to it That airline tube is what is pushing air pressure into that actuator. When the air pressure fills up that actuator, as you apply the brakes, it's going to separate the two cylinders. There is a wire that attaches to the firewall. When it fills up with air, that wire's gonna pull, and that air pressure's gonna help separate those two, and that's what is gonna apply the brakes in the vehicle when you go to stop, or slow down. You'll notice the Reed switch that's mounted on the top of the actuator. When you install this, you get it all hooked up to the battery, if you find that the light on the Reed switch is on, if you loosen the bolt on the very top, or the screw on the very top, you can slide the clamp along that cylinder, just a little bit, until the light shuts off. This kit is also gonna come with a breakaway switch. When attaching this tether from the breakaway switch to the motorhome side, it needs to be attached to the safety cable loop on the hitch. Do not attach it to the safety cables. The reason we do that is, if for some reason, anything comes disconnected and the vehicle separates, this pin needs to be able to pull. When this pin is pulled, it applies the brakes in the vehicle to bring it to a stop, so it's not bouncing around down the highway, causin' an accident or hurting or killing someone else. Now, when comparing the new Demco Air Force One to the last generation of Air Force One supplemental braking system, the last generation would come with an indicator light that would get mounted on the tow vehicle's rear view mirror. And, when you applied the brakes in the motorhome, that LED light would light up. So, you could see it in the camera, on the back of your motorhome. The problem they found is, if the sun is glaring straight down on your windshield, on the towed vehicle, sometimes it drowns out the light. So, you wouldn't be able to see it. So, you may not know whether your brakes are being applied on the vehicle. So, what they did is they upgraded to this. This is called CoachLink. On the motorhome side, it just plugs directly into a 12-volt outlet. On the backside, it's gonna have a buzzer on and off. So, you can either have it when you apply the brakes, the buzzer will go off, or not. When you go to plug this in, once you set your vehicle up, you plug this in, and you make sure the keys on here. If these three lights are lit up, that means you didn't check the Reed switch on the actuator, and adjust that. If they're not lit
