When the dealer replaced my short block, at 24k miles, they also told me the clutch and flywheel had serious burn marks, and offered to replace it at $0 labor... $1800 for parts.
I told him I have been driving manuals for 30+ years, (and I drive like an old man) and there was no possible way that was the case. He told me I could stop in and see the disc for myself. (I'm positive every dealer has a "shelf disc" and flywheel for such occasions) I told him to re-assemble, and I'd take my chances, knowing that if in fact it does fail, I'd go aftermarket anyway. That was almost 20k miles ago........Clutch is still perfect.

Just make sure they change the master cylinder!

Guys, I hate to say this but we have had multiple places we've sent parts to (new master and slave, clutch etc.) and they are only changing the slave, Shoving the master cylinder in the toolbox or something and not actually changing them! Mark the new master, Check it once you get your car back and ASK FOR YOUR OLD PARTS BACK before the work is done so they know you want them back!!

good idea... should I sharpie it?

and how easy is it to check the master?

You can see the top of it once installed, Yeah mark it with a sharpie on the top side somewhere!

Right... We had a recent customer that supposedly had everything changed we sent him, Had a sinking clutch pedal once he got it back from the shop, Called out the shop on the master (we told him the only thing that could possibly be causing that would be a bad or weak master) since it was supposed to brand new he checked further and found the original master still in the car.
The shop owner actually called me to verify the difference in the parts, Called out his tech (not sure if he still has a job)
Fortunately it was easy to do as this particular customer has a G37 which the master is slightly different in compared to the 370Z master we send with all the kits. Shop owner refunded customers money....

Sorry to hear about your problems, OP. You're fuckin right about Nissan, that's for sure :shakes head: I consider myself lucky that I got 50K out of my CSC without issue before took a precautionary measure and replaced the OEM slave with an aftermarket solution.

Please take your new clutch system and drive the hell out of it knowing that you won't have issues with the slave and the master is only $100 and easy to change out :tiphat: :driving:

Good call!! Sad that so many shops deserve this much distrust.

You haven't come out with a master, right? Have you made any progress on one in recent years? Simple yes or no answer is fine - I don't want to derail this guy's thread too much ;) :icon17:

Dealer called today, said they are working on the car. They called to verify that no bolts came in the package so they have to charge me for new flywheel bolts. About 9 dollars. All old parts will be given back to me. I specifically told them about steel hose too because this wasn't cheap. Joe I'll be reaching out to you soon for a few more parts. Thanks for the over the phone help.

Same thing happened to me, I was stranded in the middle of nowhere in Nebraska, not covered under warrenty and basically told me it was "normal wear and tear" which its not. But I love the car so...

Off topic a little and sorry for the thread jack, but just curious...is the zspeed csc reuseable if at some point you just need to change the clutch out?

We have had people reuse them but it's recommended to rebuild it if you are doing a new clutch, Just like you would change the Throw out bearing with any new clutch, If you have purchased the CSC from us we will rebuild or sell you the rebuild kit at a much much lower cost than a new unit.

I'm still a little dubious about the master cylinder being failure prone, there have been more documented failures of the heavy duty CSC then the master cylinder. If some shops are lying about replacing parts and sending cars back in non-working condition what makes you think they are even replacing the CSC instead of just topping off the fluid and sending the car back. I think there have been only 3 people here that actually know their MC went bad one of which had multiple failures which leads me to believe something else is causing it rather then getting multiple MCs in a row that are defective. I think it's more effective to say make sure the shop actually does the work they say they do rather then say all MCs are weak and need to be replaced.

I can tell you from personal experience that the master is prone to failure. I've replaced the damn thing three times in 75K miles. Myself. It's not anything other than a shitty part.

If you didn't replace it when the slave failed, it will eventually crap out on you, possibly stranding you again :ugh:

I've posted all over this forum on my experiences, but here is a-poor-attempt-to-be-brief synopsis:

( Click to show/hide )
The car was my wife's DD for the first year and a half (20K miles or so), and my DD since. She drove it super easy almost all highway miles with no traffic. I drive it pretty hard, but it still gets a lot of easy highway miles. We got 25K miles out the first CMC; luckily the pedal went soft in my garage. I received an RJM clutch pedal assembly as a gift shortly after the first replacement, and I installed it hoping to relieve some of the stress on the clutch system (more geared at the CSC than the CMC).

The CMC went out again at 51K miles at my work; the pedal was soft but had enough pressure to limp home (dead giveaway that it was the CMC). I drive out to extremely rural areas of Texas occasionally, and the last thing I want is to get stranded with no cell service on a backroad with no traffic. I had already bought the Z1 aftermarket kit for the CSC, so when the second master failed I went ahead and dropped the transmission in my garage and dumped the OEM CSC (note that my CSC never failed on me). The install went smoothly over the course of a weekend, and I've had no issues in the 25K miles since. Oh except that the CMC failed for the third time right around 70K miles (20K on the unit this time).

I'm still on the stock clutch and fully expect to get 100K miles out of it. I am open to an explanation of how I could be doing something to cause wear on the master without wearing out the clutch faster also. I flush the clutch fluid with fresh Motul RBF600 every 6 months at least. The only thing I can think of is the clutch pedal is adjustable. But I'm pretty certain is it properly adjusted since I spent several hours on it myself. Also the fact that the consistency of the mileage between the first two failures despite two different clutch pedals and two different drivers.

Do yourself a favor and ensure the master is replaced :twocents:

I think it's even noted that the manufacturer will not honor any warranty unless the MSC is replaced at the time of the CSC swap... YMMV
