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. ## 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.hk/products/21117620-8700-invisibrake-support-braking-system-with-emergency-breakaway-system-fits](https://www.desertcart.hk/products/21117620-8700-invisibrake-support-braking-system-with-emergency-breakaway-system-fits) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-09-17*
