What would cause the caliper to hang up like this?

The caliper "hangs up" or the caliper piston sticks open. We've changed the caliper twice with a well known rebuilt brand, and we've changed the brake hose. What would cause the caliper to fail like this?

The caliper was completely rebuilt and, pre-loaded with pads. The rotor was new at the first install and, turned at the second install. Additionally I replaced the flex hose. The brake fluid was not flushed but, a few monthes prior to this problem the brake lines failed and, were replaced. During that repair almost all of the brake fluid was lost and, subsequently replaced.

The two bolts that hold the caliper to the spindle were new, greased and, sliding freely. It is the caliper piston that has been failing

What moves piston back is the tension on square cut sealing ring. Pads will stay in contact with rotor. Your saying piston locks and rotor will not turn? are these new or reman calipers?
