Question for you: the pistons are very tight in the bores although I've run them through the bores w/o seals and scraper rings and all pistons moved freely. After replacement, they are still dragging. The rotors are somewhat worn on especially on the outside. Is it possible that with new pads and worn rotors that the pistons are getting cocked in the bores and dragging?
I don't think so. First I would check to make sure your steps are oriented correctly. If they are then I would next check to make sure the rotors are in spec. If they are, I think it might be prudent to disassemble the entire caliper and check the passageways to ensure they are clear.
