Clutch Problems

since the transmission is being removed, what will be the best setup to install a complete clutch kit?

in the middle of searching the best buck for complete street clutch kit setup.

This obsession with changing the master cylinder seems a little odd. As far as I can tell only 2 have failed. All the other replacements were just because the CSC failed.

A whole lot more than 2 have failed.

There are plenty of reports of CMC failure on this forum. My CMC failed first. I went ahead and replaced the CSC with the Z1 kit and a new OEM CMC at the same time. This was at 51K miles.

When you replace the slave you have to replace the master with it, or it will fail. Update on my situation from the original post, the dealership replaced the master but said it wasn't holding pressure like it was supposed to, so they are going to replace the slave again and see if that fixes it. I can only assume they didn't replace the master when they replaced the slave the first time and it failed and took the slave with it. That is not based on any fact or mechanical knowledge just the conclusion I came to based on the evidence.

I suspect you are right...

Either way, Im going to let Nissan make the car drivable again so that I can save up the funds and just replace it all with aftermarket parts. No screwing around, Zspeed hd csc, napa master, and I might even do the RJM clutch assembly for good measure. I want to spend my money on making the car faster, not replacing faulty oem parts.

See this is what bothers me, the only evidence is the dealer saying they replaced everything and the clutch system isn't holding pressure like it should and they are going to replace the csc. This makes you draw the conclusion that the dealer is lying and didn't replace the mc in the first place?! How did you eliminate air in the system or poor line installation or connections?

Since they replaced the slave less than a year ago its under their warranty and is covered, so let them replace it.
