It delivers adjustable braking pressure from 5 to 100 PSI, energizes power brakes for consistent stopping power, and connects directly to the towed vehicle’s battery to trickle-charge without draining it. With a stealthy 8"x8"x2" footprint, it installs discreetly and activates automatically with your motorhome’s brake lights, ensuring seamless, reliable braking. Proudly made in the USA with a limited lifetime warranty, it meets U.S. and Canadian braking standards for ultimate peace of mind. ## Description InvisiBrake is a fully-automatic supplemental braking system that uses the electrical connections already in place on your towed vehicle (the towed vehicle's electrical harness) to brake when you brake the motorhome — the same electrical signal that activates the towed vehicle's brake lights also activates InvisiBrake. InvisiBrake is so small (8" x 8" x 2") it can usually be mounted under the driver's seat, under the rear seat, behind interior panels or in the trunk, without sacrificing any of the vehicle's usable space. Once it's installed, InvisiBrake just works. There's nothing for you to remember — not even an on switch. Just plug in the umbilical cord like you always do and you're ready to go! InvisiBrake connects directly to the towed vehicle's battery and trickle-charges the battery during towing — InvisiBrake will never drain the battery. Includes an LED monitor for a visual reference of braking activity; an audible alert at the motorhome will warn you if the brakes have been on for too long. Most braking systems work on a 'dead' brake pedal. InvisiBrake energizes your power brakes so that you have the same power braking system while towing as you do while driving. Braking pressure is adjustable from 5 to 100 psi. Meets U.S. and Canadian braking requirements ## Features - Product Compatibility: The Roadmaster Invisibrake Support Braking System with Emergency Breakaway System fits Towed Vehicles with Vacuum-Powered Brakes - Power Brakes: Most braking systems work on a 'dead' brake pedal.

I installed it in a 2008 GMC Acadia and yes it was hard to install. I am not sure I want to do it again. I'm pretty handy as an aircraft mechanic but I felt the set up was unusually tedious to install. Lots of wiring to do and the air actuator took a bit of figuring where I could mount it. It took me 3 evenings to install it. **Q: Is the braking proportional? I have a trailer brake controller on my motor home. Will it work with that?** A: please go to this link,http://roadmasterinc.com/pdf/25-5040-00.pdf,it will explain a lot.it is not however truly proportional,and does not work with your brake controller.you set the max level of braking and when applying the MH brakes,it will ramp up to the preset levelhope that explain things,theo **Q: I dont see how it works if it doesnt hook to the brake pedal can it really activate the master cylinder to engage the brakes or is it for electric b** A: There is a cable that runs from the Invisibrake box mounted in the tow vehicle. The cable runs under the carpet and attached with a pulley system to the back of the pedal. When the brake lights on the coach come on, the box pulls the cable thus activating the brakes. Please feel free to call us if you have any technical, install, or questions. Thank you,The Hitch Spot602-321-1703 **Q: jeep wrangler 2003?** A: If you're asking if it will work on a 2003 Wrangler, I would think so. Mine is installed on a 2002 Explorer. I have flat towed it over 2,000 miles with no problems. I absolutely love it. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great Brake System *by on Reviewed in the United States August 13, 2017* I have been very happy with the Invisibrake. We have traveled about 1000 miles since install and it has worked well. Installation is not for the non-handyman and you should have a pretty good knowledge of your auto. I would also recommend that once you have decided were you want to install the brake in your auto disassemble everything in the car that needs to be removed than do a complete run through of the installation instructions and make sure everything will fit where you though it would and that it can be secured were you want it secured. The reason I recommend this is I thought I had completed the installation of the brake system cleaned up and secured my wire runs and sealed the grommet in the firewall when I focused on the brake light that gets installed in your RV. Well that wire has to run through the fire wall of your auto and connect to the cold side of your brake switch and that wire should have been run through the fire wall with all the other wires. So after kicking myself its back under the pick-up you get the picture.Once the brake installation was complete I had my wife drive the RV with Pick-up in tow around the local high school parking lot. I was in the pick-up to confirm the brake operation and to adjust the pressure.The main reason I chose the Invisibrake is because of the permanent installation. Should something happen to me while camping and my wife needs to move the RV and tow she will not need to struggle with the brake, just plug the 7 pin to 6 pin connector and break away switch and the brake system is ready.This system will also trickle charge your tow battery. I have seen friends arrive at camp grounds and their tow has a dead battery caused by the brake they choose.One thing I have found since the installation is that when I use the exhaust brake on the RV it must turn on the RV brake lights because the Invivibrake activates which helps slow us down when approaching red lights or in downhill situations. The Invisibrake does shut down after 20 seconds so you will need to get the exhaust brake to deactivate in order to get the Invisibrake to activate again. Could be an issue on long downhill runs.One issue I had and almost made me rate the Invisibrake at 4 stars was at least 6 different parts were missing from the parts bag. Both vacuum T's were missing and this delayed the installation. I first contacted Roadmaster since this over site was theirs. Once they found that I had used Amazon they would not help me. Now some of you may agree with this but I think when your name is on a 900 dollar product and a customer receives a less than perfect product, especially because you sell these parts separately on your web page, it would have been very simple for you to take my list and provide those products. Instead I had to go to Amazon and ask for a return authorization and have them send me another Invisibrake so I could pillage the parts I needed.So Roadmaster gets 3 starsThe Invisibrake gets 5 starsAmazon gets 5 stars ### ⭐⭐⭐⭐⭐ Works Great *by on Reviewed in the United States August 1, 2026* Item as described ### ⭐⭐⭐⭐⭐ Should Have purchased this system First *by on Reviewed in the United States May 17, 2015* Haven't gone on a trip yet but early test results are great. Sure this unit is a little more complex to install but once it's done the clean look is well worth it. We bought the Blue Ox Patriot removable system first, that was a waste of money for us. Our Jeep Liberty's floorboard just didn't have a sweet spot it could work correctly in. At best I got 15 or 20 miles down the road before going into alarm no matter what we try so, that just didn't work out.The Invisibrake install is as clean and hidden as they say it is. I shoved the main unit under the drivers seat and the actuator under the drivers side floorboard plastic cover. The hardest part of the install was aligning the brake pedal pulley. After the 3rd try though it worked perfectly. There's a fantastic video on youtube that shows you exactly how to install this on a Jeep Liberty. I had a several year newer model Liberty than the one in the video but, it didn't seem to matter.Luckily I had already installed the after market tail light harness so all I had to do was tap into it's wires going to the main unit and it was basically done. I would highly recommend that aftermarket light kit, it's the one you drill new lights into your existing brake light housings and you don't utilize your towed vehicle's wiring at all.I finished the towed vehicle portion of the install in 3 hours, I haven't gotten the motor home portion completed yet, apparently the wiring for the motor home is not required for this system to work. I hooked the Liberty up to my work truck for a trial run and the brakes worked exactly as they should even without the indicators for the MH being connected.This really is as simple as connecting your towed vehicle's hitch up to your MH, plugging in the trailer wiring and off you go. Once you get the brake setting dialed in like you need it I can't imagine having to ever think about this unit again.Their claim that this system charges your towed vehicles battery is beyond my comprehension. Where does it get this mystery electricity to keep the toad's battery charged? At no point does this system connect to the towing vehicles electricity so I can't think of how it comes up with the power to charge it's own battery. I have a solar charger I stick in the Toad's window and maybe that will help keep it's battery charged on long trips. I just don't buy their claim that this unit won't drain your towed vehicle's battery.In summary, it was an expensive lesson learned but this is the system I should have purchased to begin with. The easy way out rarely ever works. ## Frequently Bought Together - Roadmaster 8700 InvisiBrake Hidden Brake System - Roadmaster 15267 All in One Towed Vehicle Wiring Kit with 7-to-6 Wire Power Cord | Excludes Vehicles with Variable Voltage | Crafted from Fine Materials | Easy Installation - NightHawk Roadmaster 676 Tow Bar --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/21117620-roadmaster-8700-invisibrake-support-braking-system-with-emergency-breakaway-s](https://www.desertcart.vn/products/21117620-roadmaster-8700-invisibrake-support-braking-system-with-emergency-breakaway-s) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-09-26*
