Hi there, Jeep owners. Today in your 2022 Jeep Wrangler 4xe, we're gonna be taking a look at and showing you how to install Demco's Air Force One supplemental braking system. So we're here in our motorhome and when we press the brakes here in our motorhome, you'll see the pedal inside the vehicle will apply as well. And it's going to match the amount of pressure that I apply here on the pedal. So if we hit the brakes here, air pressure is now sent to the back to apply the brakes on the vehicle. And also on the back side of the mirror, you'll see our light illuminate.
And as an additional safety feature, you have a breakaway switch located here at the front of your vehicle. So in the event of a catastrophic disconnect between your vehicle and your motorhome, the tether here that's connected to the back of the motorhome will pull the pin. When the pin is pulled, it will apply the system to activate the brakes. So your vehicle can help to come to a safe stop. So we're gonna go ahead and pull the pin now, and you should see the light on the back of the mirror light up when I pull the pin.
And when we reinsert the pin, the pedal releases and the light goes off. And the way the system operates is it actually uses air pressure from your motorhome because when you hit the brake pedal, it actually releases air to allow the springs inside the drums to overcome that air pressure to apply the brakes. When that air releases, we can utilize that to activate our braking system over here and apply the pedal. And since we're using the air from the motorhome, the harder you press the brakes on the motorhome, the more air that it has to release to allow those brakes to apply harder. So that means more air is gonna be sent back here.
So that means our system here is gonna be truly proportional because the amount of air's gonna vary depending on how you press the pedal. And the amount of air that's sent here will change how hard the pedals press there as well. So that way they mimic one another and you get really, truly proportional braking. Some of the other braking systems out there use inertia sensors, which will only activate the brakes when it sees an inertia movement. So for example, in your car, when somebody hits the brakes, you feel that movement forward.
That's the inertia it's feeling, and it will use that to then apply the brake. The problem with those is that you can get false activations. You might hit some bumps, things like that that could potentially trigger that inertia sensor, and that can prematurely wear the brakes. Other systems operate just off of lighting signals. Whenever it gets a brake signal from the lights on your motorhome, it can activate the system. The problem with those is that it activates every time it gets the signal and certain vehicles, especially if you're using like an engine brake and your brake lights come on, it could drag the brakes all the way down the hill and you could damage the vehicle. So that's why I highly recommend Demco's braking systems. The Air Force One is my top pick for a motorhome with air brakes because it'll be truly proportional. Only activate when you're activating and you just get the best activation. Now, if you have a motorhome that has hydraulic brakes, then I would recommend Demco Stay-In-Play Duo, which uses both of the other styles that we just talked about. It uses inertia and brake signal. So that way, if it's getting an inertia signal and it doesn't see the brake signal, you won't get that false activation because it needs to see both. And the other way around, if you have the brakes on and it doesn't see that inertia, it won't apply the brakes either, which will help extend the life of your brakes and not prematurely wear them. So these are both definitely my top picks. And the Air Force One here, we'll take a look inside real quick at the pedal. It is a cylinder that's on the pedal. That is what activates it. So let's just put a quick look in there so you can see that component. So here we are in the vehicle, our brake pedal located down here has the activating cylinder attached to it, which is tethered to the firewall. So whenever it receives that air pressure, it'll extend the cylinder, which will then pull the pedal towards the firewall, activating the brakes. With our Air Force One, we also have a reed switch on here that gives us real time feedback of when the cylinder is activating. Now, when you go to flat tow your vehicle, there's five main components you're gonna need to get your vehicle safely towed behind your motorhome. You'll need your tow bar, which is the conn

Looks like a real pain in the a@@ to install. I’ll stick with the inertia wireless brake controller.

What option are you wanting to use? Strictly speaking, a brake controller is used for towing a trailer, not a towed vehicle. Just want to make sure you get the correct product for your needs....

@@etrailer RVI Brake3 possibly. Yes it would be for a towed vehicle. Im coming from a fifth wheel. learning a new system for sure.
