Ok Steve.....

I think I might get the most help from you....I have a 71 240z... The clutch is limp and I have bleed it and bleed it with no results... I then removed the slave(which is new) and the line going into the slave only had a very slow drip of fluid, not sure if it supposed to do that or have a faster leak... the slave seemed fine.... then removed the master cylinder and cleaned that.... After putting the MC back on, the line to the slave squirted out fluid when I depressed the clutch... I put the slave back on..... bleed it and bleed it some more.... and the rod doesn't even move........ Also... when bleeding the slave, I noticed that the fluid did not squirt out very strong..... Any help would be appreciated,

Thanks, Tim

If the slave is new and working properly, the problem would have to be in the master. When you depressed the clutch without the line connected to the slave you should have gotten a strong spurt of fluid from that line.

I think the problem IS air in the system. Unfortunately the MC on the clutch doesn't have a bleeder screw like the brake MC, however I think that's where the problem is. Try bench bleeding the clutch MC before installation, or (and this will be messy, so be careful with brake fluid. It removes paint!). bleed the MC installed. Just disconnect the steel line, insert a suitable fitting (many of the no assistant brake bleeders come with an assortment of fittings) and bleed the MC. Remove the fitting, add some fluid and replace the steel line. This will get any air out of the MC.

I had the same problem bleeding my brakes. Peddle was awful until I finally took the time to bleed the MC. Improved immediately. I don't think I would have ever gotten the air out trying to bleed it at the brake cylinder.

Good luck!

Thanks Bob. That is basically what I was saying. After he 'removed the master cylinder and cleaned that' (his words) I assumed that he bench bled it also. In either case the problem would be in the master cylinder either that it needs to be bled or it's not functioning correctly.
