1995 Maxima 3.0 SE Manual Clutch Problems

It could be that the fluid level in the reservoir has gone down and the system has taken in some air. I would try to completely flush out the system with hydraulic fluid by bleeding the system.

Thanks for the suggestion to bleed the system. I actually tried doing that earlier tonight after a long day at work, and it was to no avail. I'm hoping that I just did something wrong and all that is wrong is air in the line. Would the fact that the hose going from the bleed valve into a jar filled with hydraulic fluid (the suggested method of bleeding from the repair manual I bought specifically for Maxima's) was NOT airtight have anything to do with the ineffectiveness of it? It seemed to be working okay for a few minutes, but then all of a sudden we lost all pressure on the clutch pedal once again. I'm kind of at the end of my rope with this whole mess. Other than the MAF sensor, my clutch has been about the only thing to give me any problems on my car, and how it has given me problems! It DOES make perfect sense to me that there would be air in the line, as I do recall the fluid level being below the minimum line fairly recently. Is there any possible way that could have damaged the master or slave cylinders? Even worse the whole clutch kit? Once again, thanks for the input. Any more ideas are greatly appreciated!

You may have to change the clutch plate and disk. This will be more demanding financially and effort if you FIY. Will suggest a garage do it for you. My experience when the disk or plate wear is quite similar to the descriptionof your problem.
