I have a brand new Roadmaster InvisiBrake system for sale. This was originally purchased for some family friends who passed away before I could get it installed on their Grand Cherokee. I did have it out of the box to start fitting it to the Jeep, but they fell ill before I got very far. Their daughters didn’t want me to proceed with the install. They gave it to me for my Jeep, and as a way for me to recoup some of my time and sweat equity. I’m going to take a different path with my Jeep, so this system is up for grabs. Let me know if you have any questions and thanks for looking!
