I removed mine from the truck when I replaced all of the brake lines. Mine was rusted solid. I have a single line running to the rear brakes. I put it in a few wheel locked stops when I first eliminated it to make sure that I wouldn't have a rear biased brake system. That can be bad, especially in rain or snow.
I was going to try and find another and hook it back up at some point, but theres nothing more permanent than a temporary solution
