Works great
Saves at least an hour of time in hooking up, compared to another brake system I owned- love it - plug in & go.

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 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 stars The Invisibrake gets 5 stars Amazon gets 5 stars
