Clutch Slave cylinder broke @ 22K
 

Thing just went tits up! Not really any warning. Was driving then it started loosing clutch pedal pressure. I have had this happen in other cars in the past so just pumped.... got some pressure back... kept my foot on the pedal to keep the pressure there... opened the reservoir and it was nasty. Added some fluid since I was on the road on the way back (2 hour drive). Took it to the dealer and they had it for 3 days. Replaced slave and new fluid. A little shocked to say the least. Did I boil the fluid? I have AUTOX'd the car a few times and I drive it pretty solid... any thoughts?

They break regardless of how you treat the car. It's a bad design.

welcome to the next thing you'll worry about everyday you drive..... :icon14:


mine broke at 24k miles, no track time just DD.

Yeah I'm just gonna rent a lift and change mine when it happens. Hopefully I won't have to take it anywhere. Guess it will depend on my scheduling time off to get it done. Just so much quicker to do it myself and not have to wait on someone else.

Calling dealer tomorrow about mine. Hasn't failed yet but Saturday it was not acting right. Starting my historical data on it...sigh.

Mine master cylinder died last week now I guess should change the slave as well. It dies all of a sudden as well, though mine has done 45k

Are there any aftermarket ones?

They're working on the master I think. Should have one soon-ish

AFAIK you should replace the master and slave both. There is an aftermarket slave, haven't heard of a master.

Yeah.. I am thinking master and slave should be changed at the same time. I did that once a long time ago on another car just changing the slave. bad move on my part. I know they didn't change the master. PLUS... one of my hanger bolts for my exhaust was missing as well. I got it home and heard some nasty rattling... i was pissed. hanger bolt gone. Took it up there again today to get one. SMH.

What I can't understand for the life of me is that these things (clutch cylinder, fuel starvation, fluid boiling) are not grounds for recalls and just plain old re-engineering. You don't have to have it at the track for the slave cylinder to go out.. when it does you might not have pedal anymore and that could be catastrophic. just my 2 bits.

My CSC just s#it the bed at 32,000 miles. Replacing with the ZSpeed HD slave and new OEM master. And just for S & Gs, a stage 2 clutch and lightweight flywheel while the tranny is dropped. Oddly, I just got the car back from Progressive after fixing a minor brushing with a box truck when it started losing pressure, so they are picking up the check for the labor.

OP you tore it up...wow. sorry buddy. How much did the reapir cost you?

Nada cost on dat ting! was eireeeee!!! :-P The dealer took care of it after I gave them the mean mug and put my benchmade on the desk with the blade pointing in their direction. Hows your baby going.. haven't heard from you in a while.

well that is awesome...my baby is doing well. Thanks for asking;)

My clutch pedal dropped to the floor at C&O this morning here in Atl. Towed it to work. (Audi Dealership). I guess it is my turn. Going aftermarket. 56978 miles of easy driving.

Better order a ZSpeed one ASAP!

And if you want to upgrade your clutch or flywheel, now is the time

That is the plan. :tiphat:

This is the HD CSC from Zspeed. One of the guys on VQNation on facebook just got it. Looks tough. Think retail is 400.... we need a group buy on this thin with braided lines and motul oils.... :tiphat:

Ok so more or less how much would it cost to redo the whole clutch system on our car? I'm talking hd csc, flywheel, clutch, fluids, everything? I'm thinking of going FI later so will these upgrades be campatible and withstand the new power? Need help guys!!

I'm thinking just under 2k ---1.5k low side.

PM Joe awesome guy to make business with!!...i got there complete ZSpeed SS clutch kit with silent disk upgrade oem master cilinder and HD csc!!..ohhh and all fluids!!...for 1,375

Call Spencer!

:iagree:

I'm in it for $1150 (clutch/flywheel/CSC/CMC/SS Line/Fluid) parts and $500 labor.

is the HD CSC reusable if you ever change out the clutch or flywheel later on? or is it a one time use part like the OEM unit?

The HD unit is reuseable. The OEM one is too but it'll eventually fail since it's a bad design. The CMC on the other hand appears to be a one use item. If you bleed it out completely it seems to never come back.

I just hit 60,000 miles on my '09 Z. The pedal has been sticking, today it died on the highway, had to pull over and get it towed.... It wouldn't engage and I lost pressure with the clutch.... Maybe its slave cylider, or maybe I need fluid... I just hope I don't need a new clutch errrrrrrrrr..... Damn nissans.... Clutch shouldn't go out on a new(ish) car like this. :ughdance:

Why is everyone choosing the zspeed hd csc over the z1 motorsports csc which sits outside the transmission and is easier to service?
Also why do we have to choose what clutch we going to use with the car? What is we change the clutch later on while keeping the csc

Because the Z1 part has been available for less than a month and the zspeed has been available for years. Not a lot of people have used the Z1 part, while there's tons of good reviews on the zspeed part. The Z1 setup looks better, but nobody's got a lot of miles on one yet.

Because to use the outside clutch assy you have to change a piece of the housing on the transmission to mount the pivot ball for the clutch arm. Disassembling the transmission isn't my idea of fun when I could just put a Z Speed CSC in there and for a DD not change it for a looonnggg time.

I am now on my 3rd Slave, not happy.

ditto

About to have to do what you did.. happy with your set up?

Thanks Jerry

Have you installed a aftermarket one? if so did it fail?? i am about to do my CSC

Thanks Jerry

This thread is 4 years old and most of these guys haven't logged into the forum in several years. Trying doing a little research. There are tons of threads on this subject - some are even stickied at the top of the list.

You really can't go wrong with either of the ZSpeed options (internal or external).

Mine went to the floor (26,000 miles), drained or should say flushed out fluid and working fine again... flushed a second time to be safe.. works fine?? luck I guess?

Probably your master cylinder; slave cylinder usually fails catastrophically. Dirty clutch fluid contaminants can get in the cylinder seals and allow air into the system. Might be ok for a little while, but it will happen again. And eventually the seals will fail completely.
