Bleeding Brakes, Trouble with one caliper Options

[Deusexmachina77]

I replaced the two front calipers with rebuilt calipers. The system was drained. I bleed the brakes starting in the rear and going to the front. I've run into an issue with the driver's side front caliper.

I have fluid making it to the caliper, as the bottom has fluid coming out with no air bubbles. But when I went to the top bleeder, I only got air. It never filled up with fluid. I removed the bleeder screw to make sure it wasn't clogged. We peddled the car continuously, and only just air. This went on for a while.(IMG:style_emoticons/default/headbang.gif)

There are no fluid leaks in the system.
Any thoughts would be welcome.

Yes, the correct procedure is to press pedal 2 or 3 times, then hold in down position until bleeder screw is opened and then closed closed; there should be some pedal movement down as the screw is opened. Only open the screw while the system is pressurized. Always have the tip of the hose attached to the bleeder under the fluid level in the collection jar so that you can see the bubbles come out, but no reverse flow. The only way to properly bleed is to use pressure, the higher the better, so using the pedal is best for a final round.
