Speaker 1: Today on our 2016 Jeep Wrangler Unlimited, which we'll be hauling with the 2017 Coachmen Pursuit on the Ford F53 Chassis, we're gonna take a look at and show you how to install the Roadmaster InvisiBrake supplemental breaking system. Part number is RM8700.Now, as we apply our brakes in our Coach, you'll see the InvisiBrake apply the brakes in our Jeep. Now we're can apply the brake here in the Coach and watch for the red light to come on. There'll be a slight delay. Then as we release the brake, again with the slight delay, we should see that go off. Now the InvisiBrake also helps prevent overworking of the vehicle's braking system.

When we hit our brake, it's gonna give us the braking power we need that we've got adjusted back there in the back, but in the case of a prolonged stop, if we're sitting in traffic or maybe at a stoplight, after about 18 seconds, 15 to 18 seconds, our light actually shuts off, deactivating the braking system there so we're not overusing it.Now the adjustment process is pretty straightforward. What we're going to do is drive your RV around a little bit and get used to how the brakes feel. Then we're gonna hook up our towed vehicle, and we want to drive it with the towed vehicle, and we hope that the braking feels about the same as what it would if we didn't have our vehicle hooked up. Now, if it feels like the vehicle's causing us to have to brake a little more heavily, we can pull out on our knob here and rotate it clockwise to get more braking pressure, or we can adjust it counterclockwise to get less braking pressure. You want to adjust this while somebody is stepping on the brake in the RV so you can watch your psi level.

See, it's at about 60 there, so we can adjust that down or we can adjust it up to get the proper amount of braking force that we want. Once we have it set, we can just push that straight in just like that.Now, one of the benefits we find in the InvisiBrake is the hookup process. Whenever you're ready to tow your vehicle, of course you're gonna need your tow bar, you're gonna need your safety chains, but all of the controlling of the InvisiBrake is gonna go right through the wiring that comes back for our towed vehicle wiring. Just want to get that plugged in. Then the only other connection that we're gonna have to make is our breakaway switch.

Now, this should go to the frame or the hitch of the vehicle, not the safety chain, so keep that in mind. Bring that up. You can see that hook's not big enough to go around the safety chain connection point, so we can just loop it around and connect it to itself.Once it's all set up and installed, you never have to worry about it again. You just connect your normal cables as you would any other time you're getting ready to head out, and everything's ready to go, and it'll have your vehicle braking safely.Now, the breakaway switch is a very important part of this system. What happens, if we have an accidental disconnection where the towed vehicle comes separated from our motor home, when this is pull, you can hear the system activate.

That's gonna apply the brakes in our vehicle and bring it safely to a stop.And to begin our installation, we're gonna start by mounting some of the larger components. The largest one that we've got is the InvisiBrake box here. This is what really operates the whole system. We're gonna send power in, signals in, and this is gonna use vacuum to actuate the brakes on the vehicle for us. See we've got a mounting tab on each side here. In the Wrangler, it's gonna fit best right underneath the driver's seat, gives you a pretty short run to get up to the stuff you wanna get to. On the backside, we've got the small airline input here. This is gonna run from the operating unit to the actuator. We've got the 1/4" airline port here, and you're gonna have two electrical connections.One of those connections is gonna be from the breakaway switch and the power supply. I like to get these slid in before I mount the unit, just to make sure I've got a good firm electrical connection there. The second one we're gonna have is gonna be our fourpole flat wire. This, we're gonna tie it into our towed vehicle's line. It should also be plugged in here. Now, while these are still accessible, I like to tape these up. I'm gonna tape them down a couple feet. It'll prevent us from having different colored wires running through the vehicle.Then we're gonna position this so we can still get our floor mat in up here, so we can get access to our connection tabs here on each side, and so we'll have an area so we ca
