Two ideas:
1. Where did the rebuilt caliper come from? There is wide variance in the quality of rebuilds - many here including me have complained about the quality of the rebuilt calipers that we have received, although this is typically related to the rears with the parking brake mechanism (fronts are very straightforward in comparison). I was on my third replacement rear caliper on my Audi A4 when I got rid of the car.
2. It's possible that the hose to the caliper is twisted or deteriorated and swollen internally. Pressure of the brake hydraulic system is hundreds of PSI going towards the caliper when the pedal is applied, enough to push through some blockage; this pressure doesn't exist going the other way, so the caliper pistons remain extended.
