Clutch Bleeding

[The Dark Side of Will]

What are you talking about? The slave doesn't even move when you try to bleed with the non-gravity method. The fluid retracts when you let out the pedal and there's a big fucking vacuum left behind that makes the seal useless and air gets in.
The factory slaves have an o-ring behind the umbrella seal so they can seal at least a bit when there is no fluid pressure, that way the vacuum draws fluid from the master cylinder reservoir as the master cylinder piston retracts, rather than drawing in air.

n/m... must have been a long day
