Brakes were dragging and slowing vehicle: vacuum booster ,master cyl. combination valve, brake hoses are replaced and system flushed and bled numerous times.But after all of that,the front wheels still run very hot 185deg.after driving some miles.The wheels don't spin freely when turned by hand,there's no running clearance between the pads and rotors.Don't know what else to try.What else could be wrong?

The brake calipers might be getting stuck causing it to hold the brakes. Try cleaning it and I think they make lube for that (Think). I also have a dodge front brakes seem to get hot but it never holds. Good luck.
