I would like to find a way to eliminate the brakes cables I have that actuates the parking brakes on my F350 and F250. I do not care for the tail shaft parking brake set up all that much. So I was hoping for a heads up on something else that might be out there on the market. A friend of mine suggested a line lock system but I have my doubts about that as well. If I understand the way it works correctly a dead battery could send me truck rolling while unattended.
