Make sure you check the grease pins that the calipers ride on. I think this is what lead to mine warping?!? One pin was stuck causing a bind on the rotor/caliper due to it not floating and moving with the pad wear.
Just a little FYI I ended up turning my rotors, new pads, new caliper mounts(due to pins being seized inside), and fresh loaded calipers. Thank god my brother works at ford got me the brother discount
