Review: Great Brake System - 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 desertcart 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 desertcart 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 stars The Invisibrake gets 5 stars desertcart gets 5 stars
Review: desertcart is Not an Authorized Dealer - Installation was pretty straight forward. Be sure to do ALL of "before installing," procedures. I installed in a 2003 Chevy Tracker. Mounted controller/compressor under driver's seat. Brake actuator cylinder is directly behind the controller/compressor. The cylinder needs to be rather close as the actuator cable is a short fixed length. After installation and adjustment, we went out for a 2300 mile trip to LA, Las Vegas, Cedar City, Utah, then back home. We are very satisfied with the performance of the brake especially during sudden stops and down hill. However, about 2/3 of the way on the trip, the TOAD battery went dead. Didn't have a battery charger with us so waited until we were home to charge it. After charging, the battery was dead the next morning. Long story short, the Invisibrake developed a short circuit within the unit. I called Roadmaster and the tech support person helped me troubleshoot the system. Defective unit confirmed and they are sending a new unit. The tech support person informed me that desertcart is NOT an authorized dealer. Even though the desertcart site says the product is sold by desertcart, it is actually sold by Keystone, through desertcart. I believe that this is misrepresentation by desertcart. I could be wrong but, it is what it is. Also, the product is not in stock at desertcart, it is drop-shipped directly from RoadMaster in Vancouver, Washington. I actually received the InvisiBrake 2 days after I placed the order. I live just 6 hours drive from Vancouver. Bottom line: I like the InvisiBrake but am bothered by the way desertcart presents that they sell the product which, is untrue. desertcart uses Keystone to sell the products. Good news though, RoadMaster is making good on their product. EDIT: I received and installed the replacement InvisiBrake. I performed a test and found that the 5.78 miliamp draw is present in the new unit. I performed a voltage drop test and found that the battery is dropping by .5 volts per hour. In 8 hours the battery would be around 9 volts which would cause a no start situation. I have informed Road Master. I am thinking about putting a 30 amp relay in that would disconnect the battery from the InvisiBrake controller. If I do that, I will update this review.

## 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. InvisiBrake energizes your power brakes so that you have the same power braking system while towing as you do while driving.
- Out of Sight: 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
- Full Power: InvisiBrake connects directly to the towed vehicle's battery and trickle-charges the battery during towing; InvisiBrake will never drain the battery
- Made in the USA: Premium products, handcrafted by American workers, Roadmaster is a true American manufacturer that builds its products to last

## Questions & Answers

**Q: Is this hard to install?**
A: It works wonderfully. 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.
