A supplemental braking system is a must when towing a car or truck behind your RV. Without it, the weight of the towed car can create a safety hazard, strain your RV's brakes, or affect your RV's warranty. Most states require a supplemental braking system.


Automatic, Truly Proportional Braking

Air Force One is a proportional braking system. When you apply the brakes in your motor home, the system will engage your towed car's brakes at the same time and with the same pressure as those in your motor home, creating synchronized braking.


To achieve this proportional braking, Air Force One ties into your coach's air brakes. The patent-pending process uses air pressure from your coach's brakes to depress the brake pedal in your towed car. The result is uniform, real-time braking that mirrors the slowing or stopping action of your coach. Whether you lightly tap the brakes in your RV or apply them hard in a panic situation, your towed car's brake pedal will be applied in the same manner.


Many other proportional systems activate the towed car's brakes based solely on inertia. With this kind of setup, any activity that affects the forward momentum of your towed car - from the coach actually braking, to driving over a pothole - can activate the supplemental braking system and apply your towed car's brakes. This potential for false braking, which can occur simply from driving over uneven terrain, can create a rough ride for you in the RV and can also wear out your towed car's brakes over time. Air Force One is different, though. Because it is tied into your coach's brakes and is not dependent on inertia, this system activates only when you apply the brakes in your RV, so there is no false braking.


Permanent Installation with Concealed Components

Once you install the Air Force One system, it stays concealed and out of your way - both in the RV and in the towed car. Unlike systems that require you to keep the actuating box under the seat or in the trunk of your towed car, Air Force One does not take up valuable storage space inside of your car. And the components that install on your RV all remain hidden beneath the vehicle so that no room is taken up in its interior either. Because the entire system installs permanently, there is no need to constantly set up and remove this system. You never have to worry about where to store a bulky actuator box when you're not towing. And while most of the components do remain on your vehicle and RV at all times, none of them will interfere with normal driving or braking.


Coach Air Connection Assembly

Because Air Force One uses air to activate, it is a natural choice for diesel motor homes that have air brakes. The coach air connection assembly taps into your RV's air brakes and delivers the air necessary to activate the towed car's brakes through the included coiled air hose. The valves on the coach air connection assembly ensure precise airflow.


Pressure Protection Valve

A 1-way check valve collects air from your RV's brake lines so that it can power your towed car's brakes. This pressure protection valve also ensures that your RV's air lines maintain the same amount of pressure so that the braking in your RV is not affected.


Relay Valves

Metered air from the coach's brakes connects to a service relay valve. This relay valve collects air from your RV's brake lines so that it can power your towed car's brakes. When you activate the brakes in your RV, the delivery relay valve releases the appropriate amount of air to the operating unit in your towed car.


The coach air connection assembly is best mounted in a location on the RV where the air lines will not be near direct heat sources or moving parts, such as in front of the rear axle.


Note: Air Force One is designed for motor homes that have air brakes, but it will also work with RVs that have air-over-hydraulic brakes. Additional parts (not included) may be required for installation on RVs with air-over-hydraulic brakes.


Operating Unit

The operating unit, which mounts in your towed car, receives air from the coach air connection assembly. The unit then diverts a matching amount of air through a hose to the actuating cylinder that mounts on your towed car's brake pedal. That air activates the cylinder so that it applies proportionate braking pressure.


The unit goes under the hood of your towed car, so it is out of your way and always ready. Because this system is a universal fit, you can remove it from your towed car and reinstall it in a different car or truck if needed.


Actuating Cylinder

Small Cylinder

The actuating cylinder depresses your towed car's brake pedal upon receiving the air that is delivered from the operating unit. This small cylinder stays mounted on the arm of your towed car's brake pedal at all times and will not interfere with braking while driving.


Actuator on Pedal

Mount this cylinder so that it is perpendicular to the firewall when you depress the brake pedal. A clamp anchors the actuator to the firewall.


To connect the actuating cylinder to the operating unit, you will need to run the included air hose through your towed car's firewall. You can usually create the necessary, small opening without drilling. In most instances, you can cut a slit in the hood release cable grommet. Simply cut the end of the air line at an angle to poke it through the slit.


Coiled Air Hose Connection

Coiled Air Jumper

The coiled air hose, also called a jumper, connects your towed car to your RV by connecting the operating unit to the coach air assembly. When you are ready to hitch up your car and tow it, simply hook up the coiled air hose at the same time as you hook up your tow bar.


Vacuum Pressure Creates Smooth Braking

Normally, when you activate the brakes in your vehicle, a vacuum multiplies the pressure you apply to your brake pedal, creating the force necessary to stop the full weight of the moving car. On most cars and trucks, this vacuum-assist function does not work when the engine is off. As a result, many supplemental braking systems on the market have to use an excessive amount of pressure to effectively depress the towed car's brake pedal.


Air Force One reactivates the vacuum-assist function of your car's brakes when it's being towed, even though the towed car's engine is not running. As a result, the actuating cylinder does not need to apply extreme force to the brake pedal to achieve proper braking. The operating unit ties into your towed car's vacuum line with a tee so that it can use the air pressure from your RV to create the vacuum your car needs to brake gently. As a result, no additional vacuum pump is required to create the vacuum-assist function for your towed car's brake pedal. Air Force One will replenish your towed car's vacuum after each braking event so that you will get smooth, even braking every time.


Built-In Safety Features

AFO Light in Towed Car

Most supplemental braking systems have methods of letting you know you when the system itself is activated, regardless of whether the towed car's brake pedal is depressed. Such setups leave opportunities for false notification. Air Force One's system is different. This system's LED monitor connects to your towed car's brake light switch. When your car's brake light goes on or off, so does the notification light. So you can tell whether your car's brake pedal is depressed.


Air Force One Monitor Install

You can install the monitor light on your RV's dash, or you can save time by attaching the monitor light to the back of the rearview mirror of the towed vehicle . This way you can see the light from your RV's backup camera or rearview mirror. The system includes the necessary parts for either installation method.



AFO Breakaway

The breakaway system ensures that your car will come safely to a stop if it accidentally detaches from the RV while you are towing. A switch mounts to the front of the towed vehicle . This switch - which is wired into the operating unit - includes a pin that connects to your RV's hitch receiver with a breakaway cable. If the car separates, the cable pulls the pin from the switch, causing a signal to be sent to the operating unit. A reserve air supply will then apply your towed car's brakes. This system also has "total coach protection" built in. If there is separation, the RV's air supply is sealed off, so its brakes will continue to function as normal.


Air Force One meets Federal Motor Vehicle Safety Standard (FMVSS) guidelines requiring that supplemental braking systems use a separate air supply and activation relay valve.

I consider myself an average driveway mechanic. Give me a good set of instructions and the right tools and I'll tackle just about any project. But to make sure you don't get the wrong idea, I don't do mechanic work for a living, it's just a hobby. Having said that, the SMI Air force One installation was reasonably straightforward with the exception of the coach air tank assembly. I have a 2005 Itasca Meridian 34 foot DP, and I had a heck of a time finding a space large enough to hang to the tank assembly on the under carriage. Even so, I had to add a brass fitting or two to change routing of the air lines for clearance. After the tank assembly was installed, I fired up the diesel and discovered that my air system would not hold pressure. So I crawled back underneath the motor home and found that I hadn't firmly seated one of the air lines to the tank assembly. Once I reseated the air line, the pressure held steady. I found the instructions to be very helpful, just bear in mind that installations on different brands of coaches may require some ingenuity to make things fit. Personally, I found it took more time to install the equipment in my car than it did on the motorhome. Finding a place to install the operating unit and hoses so they would not interfere with normal engine maintenance takes a lot of thought. Also finding a route from the passenger compartment to the engine compartment is a definite challenge. All in all, the instructions are complete, but it's still a lot of work. If you don't like puzzles, trial and error, and being a contortionist, I would leave the install to the professionals. But if you don't mind bending your body like a pretzel and are handy with tools, go for it. And don't be afraid to call SMI or e-trailer for help. 237647

2016 GMC Canyon

Vehicle 2016 GMC Canyon Diesel. Installation of the SMI Air Force One supplementary braking system was not too difficult. The instructions from SMI were good as was the video from etrailer. The only reason that I didn't give it a 5 star is because the air cylinder installation on the brake pedal was complicated by an unusual shape of the brake pedal arm. I eventually found a solution. Tapping into the truck's vacuum line was a little difficult but the kit included everything I needed to T into the vacuum line and install the check valves. All in all not a bad installation, this summer we'll see how it holds up. 371137

Thanks for the follow up letter. We have only towed the vehicle twice for very short distances since installing it but will be going full time on the road in another week and a half and will put it to the test then.

"Out of sight, out of mind" would be the best description I could offer for the Air Force One supplemental braking system! When properly installed, it's effective as well as quick and easy to hook up. Connect the tow bar, safety cables, safety switch cable, tow plug and air line, you're done! Five minutes at most. I did add a couple of features to my towing system: 1. Using a relay and the extra wire in the connector to the coach, I installed the LED indicator strip on the dash of the coach; no need to rely on the back-up camera to verify operation of the brake cylinder. Coaches that have a tow connector are usually equipped with a power wire to the cab for electric brakes - this wire is a good way to get the indicator signal to the front of the motorhome. 2. I used the 12 V power connection from the coach to connect a charging wire to the car battery to ensure it would not discharge; I used an auto-resetting breaker with a rating below the glass fuse in the 12 V circuit to prevent a fuse from blowing if the charge current gets to high. In all, a great investment! I have an article I wrote on the install if anyone is interested. 598284

Very happy with etrailer for the purchase of a Blue Ox tow bar with needed hook ups for lights, etc and an Air Force One Brake system for my 2018 F150. Crystal did a great job of comparing options and matching pricing from across the web. She offered free installation. The Installer, Shane was awesome, I wanted all hookups hidden by the front plate on the F150 when not towing, Shane came through and then some. Finally, the manager Robert was excellent on follow-up as we had some air leak once we got home. etrailer stood behind everything and follow was exceptional. Very pleased! 553768

Great breaking system , I installed the unit on my 2016 Equinox ,and our new 2018 Tiffin Phaeton.Most dealers don't want to cut into the Coach air system ,hey grow a pair it's no big deal . They just want to sell you the big clunky box then you have to deal with that . Air Force 1 just disconnect jump in , throw a switch and go . Recommend to all . 580338

2014 Honda CR-V

AF1 is amazing so far. I did the installation by myself. I have a 2014 Honda CR-V and bought it for towing. Watching the video helped me through it. The car installation portion was pretty straight forward. The video is better than the instructions overall, but I read through the entire instructions before beginning. I was able to install the RV tank without putting the rig on a lift. Depending on how big you are and flexibility, it can be done with the RV on the ground...it just takes longer. Also, I would recommend knowing where you are going to mount your RV tank. I mounted the tank near the rear and didn’t have enough brake tube after doing the car. Picked up an extra 20 ft at Autozone or order the tube with etrailer. The customer service center is very helpful too. Many thanks to Mariah for the outstanding assistance. Finally, I would say that if you order the brackets to mount the emergency brake away for your car, you may have to cut them down with a grinder. It is so much nicer not putting the brake buddy in the car now. Looking forward to enjoying it on trips. I drove the rig about 20 miles yesterday, and the light came on and I honestly couldn’t tell the car was back there other than looking in the video and seeing the light on the car during braking. Highly recommend this unit. 851764

  • Estimated Installation Time for SMI Air Force One Braking System
    I reached out to my contact at SMI and he said that for both the RV and your 2017 Chevy Silverado you're looking at a total install time of around 5 to 6 hours for the Air Force One Braking System # SM99243. I have attached an installation video on the 2017 Silverado that you can use for reference along with the written manual.

  • Does LED Indicator Light of SMI Air Force One Light Up When Vehicle isn't Connected
    The LED notification strip that typically attaches to the rearview mirror of the vehicle being flat towed will not always light up when the vehicle brakes are applied. It would have to be connected to the tow vehicle. I attached a diagram for how it wires up as well.

  • Air Force One Breakaway Not Working on my 2014 Honda CR-V
    When the breakaway switch will not activate the air cylinder to apply the brake pedal on the SMI Air Force One # SM99243, the first thing to check is the inline fuse at the towed vehicles battery. If it is blown it will have to be replaced. If the fuse is good the next thing to check is that the air lines and check valves are properly installed. If the airline in is routed to the out and the out is routed to the in, the system will work when attached to the coach but the breakaway system...

  • How to Make the Airline Connections on the SMI Supplemental Braking System Part # SM99243
    There are two airlines that must be spliced into on the coach which will then run to the air tank assembly included with the SMI Air Force One Supplemental Braking System part # SM99243. One of these lines is for supply-air and the other is for metered-air. The supply-air line is a 5/8" diameter hose (usually green but not always) which goes from the service relay valve to the braking air tank (see first photo). Once you find this line you will need to cut it in half and install the...

  • How Installed SMI Air Force One Receives Power While 2016 GMC Canyon Being Towed
    The power and functionality requirements of the Air Force One System, Item # SM99243, are taken care of when it is directly attached to the vehicle battery during installation. Everything will still function even if the negative cable is off of the battery because only the positive terminal and a ground location are needed The Air Force One works by engaging the brakes for a towed vehicle when it receives air from the coach air connection. It diverts a matching amount of air through...

  • Braking System that Doesnt Apply Toad Brakes with Exhaust Brake
    We have a supplemental braking system that is ideal for you situation. The Air Force One, part # SM99243, will do just that. The Air Force One only engages your toad's brakes when the air brakes of your motorhome are applied. And since they aren't being applied when you're using your exhaust brake the toad won't brake just from using the exhaust brake. I've linked a video of the Air Force One being installed in a new CR-V for you.

  • Video of Install for SMI Air Force One Supplemental Braking System on 2017 Ford F-150
    We are not affiliated in any way with installers apart from our own, which are located in Wentzville, MO so there is not a list I can offer for installation of the SMI Air Force One Supplemental Braking System for Motor Homes with Air Brakes # SM99243. However, if you make some calls to certified mechanics or shops in your area you are very likely to find someone who is qualified to do the installation. I did add a pair of links to video installations showing this system being installed...

  • Can the SMI Air Force One Braking System be Installed if Vehicle Has Adjustable Pedals
    That is a great question! Demco/SMI has actually already thought about vehicles with adjustable pedals, like your 2019 Ram 1500, when installing the Air Force One # SM99243. Basically you just need to adjust the pedal so that it sits closest to your seat when installing the Air Force One and then move it to this position when flat towing your pickup. Their official statement (found in the attached installation instructions) says: Special attention must be given to vehicles with adjustable...

  • SMI Tow Bar Braking System Recommendation for 2018 Ford Edge
    The Air Force One, part # SM99243, is a great braking system for motorhomes with air brakes. Other systems still work but this one prevents false braking when the coach's brake lights are activated with the exhaust brake. I attached an install video for this kit on a similar Ford Edge as yours for you to check out as well. For a base plate kit they'd need the part # BX2657 which is a confirmed fit for the 2018 Edge. For a tow bar the part # BX7380 would be a great option. For...

  • Parts Needed to Flat Tow a 2010 Buick Enclave with a Motorhome with Air Brakes
    For your 2010 Buick Enclave I recommend using the Roadmaster EZ Crossbar Style Base Plate Kit # 523149-1 along with the Roadmaster Falcon 2 # RM-520 and the 6,000 lb coiled safety cables # RM-643. For a complete flat towing setup you will need a base plate kit, tow bar, safety cables, vehicle tow bar wiring, a supplemental braking system, and possibly a high-low adapter. I like recommending the Flexo-Coil Wiring Kit # RM-15267 because it allows you to also installed the Charge Line...
