NWJeeper is right, systems like brake buddy and similar units are designed to work with vacuum assisted power brake units and apply the extra pressure needed to overcome the "hard Pedal" when there is no vacuum assist. These units, however, will NOT work with vehicles that have the newer Hydro-boost power assist (electric boost). That I was told directly from the Brake Buddy Tech support. They will cause the toad to go into a skid and lock up the brakes, if your toad has the hydro-boost system you have to go with a system like the Unified Tow Brake by US Gear or a similar type of system. Been there, done that, just so you know.
