Clutch Cylinder. Repalced master

It's about the same as the brakes:

Get the bleeder at 12 o'clock (it helps to get it loose wherever you can, then roll it up to 12 o'clock and grip the flats of the slave cylinder with vicegrips so it'll stay there while you work. A box end wrench is likely your best candidate for working with the nipple once loosened)

Put a length of (preferably clear) tubing on the end of the nipple down into a glass jar that has a small amount of fresh fluid in it. (end of hose much reach into the fluid)

Top up the resevior

Have a friend start to depress the clutch pedal slowly and crack the bleeder open once they tell you they have begun pressing

Friend should let you know that they are getting close to the bottom of the throw/end of travel so you can close the bleeder before they get there (you want the nipple closed before they actually hit bottom)

Once the bleeder is closed, have friend let off the pedal

Wait a few seconds then repeat the above steps until no air bubbles come out of the bleeder

On the last go-round, snug up the nipple, remove vice grips if used, then tighten the nipple to 4-6ft/lbs (as in not stupid tight), top up the resevoir again, go for a test drive.
