I actually had to put it in 4x4 to pop that thing out of there. Stopped at Napa on the way home, grabbed all new brakes, went right home and fixed it all. Had to use the e-brake for all my stops. Slid into the garage door pulling in the driveway haha. That was at 50k. I think what really happens is the calipers stick/seize and then from that they generate so much heat they end up cracking the pistons. Including the one's that came on the truck, I'm on my 5th caliper in the back. Just had everything replaced under Napa lifetime warranty though, so at least I didn't have to pay for it this time. A buddy of mine who is a Ford tech says he sees the cracked pistons a lot on trucks that are worked hard, like a plow truck or a lot on the f550's and such.
