I fought it for a while without success until I finally decided to give up and pull the whole thing out..from the slave to the reservoir. It took a little creative threading and unthreading but once I had it out, I just hung it up, got all the connections pointing up and gave about 4 strokes to the slave and watched the reservoir until the bubbles quit. Took about 1 minute to do. Then I put it back in. It was easier putting it back than taking it out. Worked like a charm. Bottom line, on a new system or one where air has gotten into the master...take it all the way out and bench bleed it.
