I do not recall where I learned this, but I have used it with 100 percent success for quite a few years on a variety of cars with hydraulic clutches.

If you are replacing the clutch master cylinder, you must perform a bench bleed. This involves placing the cylinder in a vice to hold it steady, then slowly push the plunger in with a tube full of brake fluid attached to the cylinder inlet. Repeat several times until the cylinder is full of fluid.

system bleeding:
1. push the pedal down several times, if necessary pull the pedal back up with your foot.

2. remove the slave cylinder from the bellhousing, but do NOT loosen or remove the fluid line.

3. going slowly - fully depress the slave cylinder plunger and slowly release the plunger several times.

4. Reinstall the slave cylinder.

that's it. done.
