I have a bit of a problem changing the brakes on my truck. I seem to have a different set up than most of the others Ive seen in these trucks. I do not appear to have the pin/key style that Ive seen. I have a hardware kit that has two brackets for the bottom, what appears to be a bent piece of metal that is possibly a spring, and some pad clips. I have no idea how to get them off. I took out the bolt holding the metal bracket in place, but nothing got any looser.
