Diecutter

I brought it in and initially was the e-brake, rusted and froze. Every time I would back up, it would turn the e-brake pads and jam it into the drum. They are removed. I'm taking it back in next week and they're going to start with the flex lines and go from there. I also read on another forum to get them to lock up again and loosen the bleeder valve and if fluid comes out and the pressure releases, it's something before that and keep going toward the master cylinder until the brake won't release after loosening a connection, it should be just before that where the problem is. Any thoughts on that?

I have a 2001 silverado and the exact same thing is happening with my truck, brakes are dragging and the rotors are getting hot. Ecxept I don't know the history of the brakes, (just bought it) Did you ever get that problem solved and if so, what was it. Back brakes have been replaced and calipers totally cleaned and free.of rust and crud.
