Did you prefill the master cylinder with fluid before installing it? If not, you are working air out of it and it will take you a while. I've adjusted that rod once and that was enough for me. It ws a real pain..

I always bench bleed before I install. Brake master cyl or clutch. Saves time getting the air out before you fill your system full of it and have to spend all that time at the wheels/slave cyl bleeding out air.
My nickels worth....(you know two cents won't get you anything anymore)

Ken,
Could a leaking slave cylinder cause the same symptoms? Or would it be the opposite? When mine went south it was like I had air in the line - Always having to pump the clutch pedal to get enough fluid in line to disengage the clutch .

I don't recall one ever sucking air back into the system, but I suppose it could happen. Sounds like there is air trapped somewhere, but I can't see where. I would be more apt to blame the master cyl not holding tight (sort of like the brakes when you have a leaky master cyl) than the slave cyl. I had similiar problems and with a healthy diet of AutoX I replaced both at the same time when I got a hint of trouble. All has been well since, over a year.

I have an 83ZX and I think I may need to replace and/or rebuild my master and slave cylinders too. I seem to have the right amount of clutch pedal free play, but I have to push the clutch pedal about 2 inches before the slave cylinder begins to move. Also, the slave cylinder only moves less than 1/2 inch. Are these indications of a need to replace or rebuild. I'm no expert, at diagnosing symptoms, but can do the work. Thanks for any advice.

Kip you should go back to the autoparts store and get another master clutch cylinder. Master Cylinders for brakes and clutchs can be defective straight from the factory. Just take it back and tell them it is defective.
I know some people that had to go back several times until they found one that worked.
hope this helps you out.

I have never measured the travel on the slave cylinder, but it would be interesting to see what the stroke is. You may want to consult a repair manual to make sure clutch pedal free play is adjusted correctly. The price of the new master cylinder and slave cylinder decided it for me. I too was not sure which may be my problem, since the price was right, I replaced both.
