I could use some advice on Master/Slave cylinder issues...

nr7

Please forgive me for not having done all the research that might be expected by forum veterans, but I am currently 1.5 months into a 3.5 month road trip around the lower 48, which is limiting my forum search/reading time.

2010 Roadster Sport/Touring 6 spd. Purchased with 28000 miles in Feb. Now at 38000+ miles.

A week or two back (can't be sure), I started noticing an occasional ca-thunk from my clutch return pedal when shifting quickly, like it sounds when your foot slips off the partially depressed clutch pedal.

On Monday that turned into the clutch pedal sticking about 4 inches from fully returned and I could flick it up with my toe. I checked my fluid level and it read full. This lead me to deduce that I likely had slave cylinder issues, even though the previous owner said he had replaced the clutch at 10 or 15k miles, leading me to surmise that he may have replaced the slave at that time.

I took the vehicle to a performance oriented auto mechanic in Savannah. He said he was overbooked, but agreed to have a quick look. He attempted to bleed the system which led him to discover that the lines or perhaps reservoir was filled with goo from deteriorated rubber parts.

At this point the pedal would no longer return at all. A discussion with Joe at Zspeed informed me that he is out of the parts needed to address the issue and relocate the slave. Upon hearing that the pedal was now not returning at all, Joe suggested I have this shop replace the Master cylinder with a new OEM one as this might get me moving again and buy me sometime to further trouble shoot and address the issue.

He said if the slave was not too bad, that this may get me moving again. On his advice, I had the CMC replaced and much to my surprise, the clutch now drives pretty much like it did before.

Is there a chance that my slave cylinder is OK and a new master is all I needed?

How do I determine if the slave is going out as well? If it is going out how much longer can I drive it before I will start having more trouble?

Is there a good 370z mechanic that is north of Charleston to which I might have Zspeed ship the parts and have further repairs executed.

Any advice is appreciated.

Thanks
