Expert Answers about Tow Bar Braking Systems

• Troubleshooting the Brake Lights Not Coming on in my Flat Towed Vehicle
• It sounds like you are more likely having and issue with your tow bar wiring rather than the Demco SBS Air Force One Supplemental Braking System # SM99243. You can test this by testing your Air Force One system. Depress the break and verify that the LED indicator light is coming on and that the actuator is pulling the brake pedal in your towed vehicle. If that is happening, then the Air Force One is working properly. The Air Force One is not what provides power to illuminate your brake...

• Will Supplemental Braking System and Tow Bar Wiring from Motorhome Overload Brake Lights on Enclave
• You may need a brake light relay # RM-88400 to keep the Buick Enclave brake signal from overriding the turn signal sent by your motorhome. The relay is needed on towed cars with combined lighting if you are using a supplemental braking system. Combined lighting means the vehicle has turn signals and brake lights on the same circuit. To determine if a brake light relay is needed to properly wire your vehicle to be towed, answer the following questions. Are you using a supplemental braking...

• Turn Signal Causes Supplemental Braking System to Apply Brakes on Towed 2004 Honda CRV
• Sounds like you are going to need a Vehicle to Vehicle Tail Light Converter like # 118158. This converter is used when a motorhome with a 2-wire system is towing another vehicle with a 3-wire system, by way of a tow bar. If your supplemental braking system is spliced into the right turn signal (for example) then you will take the converter's green wire and splice it into the right turn signal wiring and run the red wire to the supplemental braking system.

• Even Brake is Braking When it Should Not Be
• The Roadmaster Even Brake Portable Supplemental Braking System # RM-9400 does not have a part that attaches to the bar under your Jeep; it is likely that whomever told you that was referring to the seat adapter for the Roadmaster BrakeMaster, which is a different system. If you are getting braking issues it is likely the position of the adjustable seat pad needs to be adjusted up or down.

• Tow Bar Lighting Solution for 2019 Ford Ranger that Doesn't Require Brake Light Relay
• Since your 2019 Ford Ranger has a separate turn signal from brake light signal the diode kit that would work the best is a tow bar lighting kit for separate turn signals like you mentioned like the Roadmaster part # 154-792-118158. This will allow your brake lights and turn signals to function properly without requiring you to also use a brake light relay.

• One Arm of Roadmaster Falcon Tow Bar Unlocks When Motorhome Brakes
• Over time, dirt and debris can build up on the retracting portion of the tow bar arms. When the arms retract, this dirt is carried into the interior of the tow bar, and can foul out the locking mechanism on one or both of the tow bar arms. This is what I believe happened. You can try cleaning the tow bar using the # RM-9911 Voom spray cleaner, and see if that solves the problem, but I (and my Roadmaster representative) believe your best bet would be to use the # RM-910003-60 repair kit...

• Does The Battery Need To Be Disconnected To Flat Tow A 2022 Lincoln Nautilus
• Typically the requirement to disconnect the battery is from the manufacturer but I looked through the owner's manual for both the 2021 and 2022 models and they don't list anything about disconnecting it under the recreational vehicle towing section. Roadmaster, one of our suppliers, does has a note saying that the battery should be disconnected with part # RM-766 to flat tow and that there could possibly be more than one battery in the vehicle that will need to be disconnected. I've never...

• Troubleshooting Brake Lights Not Working When Flat Towing 2018 Nissan Frontier
• The Blue Ox Patriot Supplemental Braking System # BLU37TR is a great system that will power the brakes in your Nissan Frontier at the same time and with the same intensity that you apply to them in your RV. This system will not, however, power the brake lights on the vehicle. To allow your Frontier to accept the tail light functions from the RV, you will need to install tow bar wiring. If you have not already done this, I recommend the Roadmaster Diode Flexo-Wiring Kit # RM-15267. This...

• Parts Needed to Flat Tow 2017 Ford C-Max
• Since you have a Roadmaster tow bar the correct base plate kit for your 2017 Ford C-Max is the part # 524432-1. This is what attaches to your vehicle frame to provide the attachment for your tow bar. For lighting/safety cables, locks, and covers for the tow bar we have the Roadmaster Falcon All Terrain kit part # RM-9243-1 which comes with all of that as one part number. The diode kit that comes with this allows you to splice into the taillight wiring so that your RV controls the vehicle...

• Towed Ford Explorer Battery is Dead After A few Hours of Flat Towing Behind Itasca Motorhome
• The Roadmaster InvisiBrake Supplemental Tow Bar Braking System # RM-8700 is designed to deliver a trickle charge from your running motorhome's electrical system to your toad's battery while you're underway. This power feed is dependent on good ground connections between both the motorhome and InvisiBrake, and between the InvisiBrake and the toad. You can check to make sure all electrical connections are sound and that there is no corrosion on connectors that might be impeding the charging...

• Parts Needed to Flat Tow 2017 Jeep Grand Cherokee Limited Behind RV
• The first thing you need to flat tow your 2017 Jeep Grand Cherokee Limited is a base plate kit like the Roadmaster part # RM-521440-5 which is a confirmed fit. I attached an install video for this for you to check out too. In addition to the base plates, you will also need a compatible tow bar, safety cables, lighting, and supplemental braking to flat tow your vehicle. The most popular compatible tow bar is the Falcon All Terrain, # RM-522. This has non-binding arms which makes the setup...

• Troubleshooting Brake Light Failures When Flat Towing A 2019 Buick Envision
• The Roadmaster Even Brake Portable Supplemental Braking System # RM-9400 wouldn't affect your brake lights in that manner. You most likely have a short or loose connection in the tow bar wiring which is causing the turn signal to work but not the brake light. You'll need to check all of the wiring running from the tail lights to the 4 or 6 wire port you have on the front of your 2019 Buick Envision for any shorts, kinks, or brakes in the wires or a complete disconnection of any wires. Your...

• What is Causing Back and Forth Bucking on Jeep Wrangler
• While you can use the Gen-Y Torsion 2-Ball Mount w/ Stacked Receivers # 325-GH-1024 with a Roadmaster tow bar like the StowMaster # RM-501 it will not be a solution to fix the back-and-forth bucking you are encountering with your Wrangler. Does your Jeep have a supplemental braking system? If not then that would be the solution, and if you do have one then it may not be working as well as intended. I have added a link to a help article on supplemental braking systems for you to check out...

• Potential Issues if a Demco Air Force One Braking System is Engaging the Parking Brake on a Sierra
• I have not come across this being an issue when using the Demco Air Force One Supplemental Braking System # SM99243 in your 2023 GMC Sierra 1500 before. So I went ahead and reached out to the manufacturer to see if they have come across this before and I have included what they were able to tell me below. "It sounds like when the customer disconnects the negative cable, the truck is still finding a ground through either the tow bar or lighting cables. As a result the truck acts as if...

• Can the 2019 VW Jetta Be Flat Towed?
• Unfortunately, it's not quite that simple because not all FWD vehicles have transmissions that can be disengaged that will allow for flat towing. You'll want to consult your owner's manual for confirmation but from what I've found it looks like the 2019 VW Jetta, which is FWD, can only be towed on a tow dolly like the Demco Kar Kaddy # DM9713045 . For vehicles that are able to be flat towed, you need a number of components in order to flat tow including base plates, a compatible tow bar,...

• Troubleshooting Sway Control Issue with Fastway e2 System
• The Fastway e2 system you have should not need any additional sway control and won't work with any additional bars. The biggest issue when you experience sway with a system like the # FA92-00-1000 is either an underrated system or a poorly adjusted system. An underrated system doesn't account for the total tongue weight which includes the loaded trailer tongue weight as well as any additional cargo behind the rear axle of the tow vehicle. I've attached the installation instructions to...

• Trailer Brakes Dont Engage Completely and Brake Controller Not Showing Full Power
• It sounds like there might still be some wiring issues in addition to the one that you found, but I think your best bet to start with this issue is by pulling the pin on the breakaway system on the trailer; this will allow us to figure out if these issues are being caused by the brakes/wiring or if the problem lies somewhere else. If you pull the pin and the brakes don't lock up completely, the issue is going to be on the brakes and/or brake wiring; if the brakes lock up completely, we...

• What is Shifter Process to Allow 2019 Jeep Cherokee Trailhawk to be Flat Towed
• I have attached for you below the recommended procedure to flat-tow a 2019 Jeep Cherokee Trailhawk per the owner's manual. The process does look elaborate and silly...but following these steps to the letter allows the transmission to be in a position where the wheels can turn without causing any damage to anything. 1. Bring the vehicle to a complete stop on level ground, and shift the transmission to park. 2. Turn the engine off. 3. Turn the ignition to the on/run mode, but do not start...

• How to Fix Death Wobble While Flat Towing a 2018 Ford Edge
• The Jeep fix won't work for Ford because they are different manufacturers. I did some research and it looks like you can contact your local Ford dealership for a wiring kit, or another solution I saw people talking about is using bungee cords and wrapping them around the steering wheel and your driver's seat frame to keep the steering wheel taut to help prevent that death wobble. For a complete flat towing setup you will need a base plate kit, tow bar, safety cables, vehicle tow bar wiring,...
