    Ideally you'll compress it, tap it, and rotate it all around while tapping it... WHILE someone is mashing the pedal and you're bleeding it, all simultaneously.

    The power bleeder alone didn't do it for me. We had to do all that to get all the air out.

    And it can take A LOT of tapping. Took several tries and over an hour with mine, with someone who knew what they were doing...

    I had trouble bleeding a slave cylinder. I went to O'Reilly and got Timing Gear Puller a loner one. take the center bolt out of it. unbolt the slave. the center shaft will fit in to the center of the timing gear puller so it won't slip. now take two long bolts and nuts put them through the slave and the puller and tighten them evenly till the slave is fully compressed. Make sure it is completely compressed. Hook up a pressure bleeder. when you start bleeding the slave move it around and tap on it till all the air is out.

    I tried everything, putting a wood block between the slave and clutch arm. the storm method, the push slave method, nothing worked. I went through a big bottle of brake fluid, still no clutch. I did this and it took about 2 min to bleed it. The key is to get it completely compressed so it can't extend, not even a little and then move it around and tap to get all the air out.

    Willing to bet the plastic throw out bearing has grenaded itself. Hopefully, it didn't tear up things too bad in the clutch assembly.

    Thank you for your responses.

    I put in a new clutch slave and carefully bled it. There is still no resistance in the clutch pedal. When the clutch pedal is moved manually, I can hear the fluid going in and out of the slave cylinder. The clutch lever does not move. Should it move when the clutch pedal is moved? Would a bad throw out bearing prevent it from moving?

    I didn't tap it. I'll try that before I attempt replacing the throw out bearing.
