I recently replaced all the clutch hydraulics in my 924S. After looking at a lot of different procedures in these forums, I consolidated and developed this procedure that worked for me the first time I tried it (your results may vary):

This procedure assumes you have replaced one, or all, of the hydraulic components in the clutch system:
a) clutch slave cylinder
b) clutch master cylinder
c) clutch pressure hose
d) clutch reservoir hose.
This procedure also assumes the clutch mechanical components are in good working order, the clutch power spring has been adjusted to the correct length, and the master cylinder extension rod has 3mm of free play.

• Removing the starter is optional but improves access to the clutch slave bleed nipple.
• Raise the rear of the car to get the clutch slave at least level or higher.
• Pre-bleed by using either a syringe to pump brake fluid into the clutch slave cylinder from below, or by using a motive power bleeder to pump brake fluid in from above.
• Close the clutch slave bleed nipple.
• Make sure the brake fluid reservoir is full.
• Find the clutch inspection hole in the bell housing where you see the clutch slave extension rod contacting the clutch fork.
• Insert the flat blade of your tool (large screwdriver or small prybar) in front of the fork.
• Pry the fork back to push the clutch slave extension rod into the clutch slave body.
• Sweep this motion several times, while keeping pressure on your tool to limit the speed that the slave piston returns each time.
• Make sure the brake fluid reservoir remains full.
• While kneeling with the driver’s door open, grasp the clutch pedal firmly.
• Manually push pedal to floor and pull it up about an inch or two. Repeat this motion about 10 times.
• After 10 pumps or so, slowly pull the pedal all the way up and then repeat the short travel 10 pumps or so again, and finish by slowly pulling the pedal all the way up.
• Top off the brake fluid reservoir.
• Now manually pump 5-10 full strokes.
• Sit in the seat to assess the clutch pedal feel.
