Edit:Read the TSB again. That procedure is for the slave cylinder, or if air is in the line downstream from the master cylinder. Now look at the master cylinder diagram on the last page that shows where air gets trapped. You aren't going to get air out of the master cylinder unless the air can exit the master cylinder through one of the two lines, which isn't going to happen with it installed. If you bled your hydraulic system by pumping the pedal it was becuase the air was somewhere else other than in the master cylinder.
Ok, maybe we are both right? I'm not sure.
Step 3b would seem to imply that if the master is fine (pedal is hard), then continue with the rapid presses of the pedal. But if it's spongy, then do steps 4 - 7.
What I don't get is what steps 4-7 could possibly do here, as that is basically the same thing as bleeding it from the slave (ineffective at removing the air from the master).
What I do know is that the rapid stomping on the pedal does work. You cannot tell me it doesn't, because I have done it many times, even after air being sucked into the master from a leaky slave. What I (unintentionally) left off is I also very slightly crack open the bleeder so that fluid is also escaping from the system at the same time I'm stomping the pedal. I don't know if that makes a difference, but not once have I needed to de-install a clutch MC to get it properly bled.
