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.

I tried for 20 min. Nothing is coming out of the top bleeder screw, and nothing is leaking. I even removed the screw. Not a drop.

sadly....push pedal to floor, tighten bleeder...then do that again and again.
pumping just pushes air in an out.
I use a vacuum bleeder, its easier.

Which vacuum bleeder do you prefer? I tried one that hooked to my compressor, and all it did was suck a whole liter of expensive fluid out. Granted, I didn't know what I was doing but I kept waiting for air bubbles to stop.
