Quote: Yes even with the bleeder unscrewed, the piston still pushes on the rotor...making it hard to turn
Piston is not pushing on the rotor, it is just not retracting enough. Dirt, rust, misalignment, damaged pistons(chatter marks), etc. There should be some "slight" drag to keep foreign material from getting in between the rotors and pads. You should be able to spin the tire by hand and get at least 1.5 tire rotations out of it. Time to tear it down and find the problem - before this thread turns in to a real drag.
