Brake dragging on passenger side,advice/help needed

Well, the fact that there isn't a pressure release from cracking the bleeder and that the rotor doesn't turn freely after you've cracked the bleeder (and done nothing else) would suggest that it isn't a hydraulic problem. If the hydraulic system was holding pressure and keeping the brakes applied cracking the bleeder should release the pressure and temporarily fix the problem until the brakes are applied again.

That would tend to indicate a mechanical problem with the piston or the caliper not returning. Are there any obvious differences that you see between the driver and passenger side? I assume you used the same install procedure on both sides, and the driver's side is working properly yes?
