I think my master slave cylinder or maybe CSC just went

Man, that really sucks. Hope you get it all sorted out. The reservoir is basically there to prevent air in the lines. If there's a tiny bit of fluid left in the reservoir, you can still top it off. But if it's gone completely, there will be air in the lines when you add more, and that requires that you bleed the system.

I read the directions from the manual and we could do it but I don't want to chance it especially since it's under warranty

Yeah, and I meant to add the fact that it was randomly out of fluid would be concerning enough for many people to just have it towed to a competent shop.

it is now 8:09PM and my flatbed tow truck that was supposed to show up at 5pm is still not here. USAA is now cancelling it and getting me another one. Maybe I'll get to bed before midnight considering i'm in an all-day workshop tomorrow again.

geeeeez. damn tow truck drivers, thats ridiculous.

dmhenderson · 04-09-2013, 09:09 PM

Called USAA to request a new towing company. I know the guy who owns it because he's in a dart league with one of my friends. Had no idea they were an option. They got here in 10 minutes o_O

StangerGT · 04-09-2013, 09:23 PM

Dealership is the place man...

You lost all that fluid, so something is wrong... if they find it, it should all be covered. refill and fix.

dmhenderson · 04-09-2013, 09:33 PM

Yep, it's at the dealership now. The guy hooked it up and I warned him about the wheels and then stood behind the car.

He goes "I'm going to release the parking brake now"
I said, "Ok"
He said, "You might not want to be standing behind the car"
I said, "Well if it rolls backwards and squashes me you're going to have bigger problems than a wrecked car you were supposed to tow"

He laughed.

MyKindaGuise · 04-09-2013, 10:54 PM

I for one am excited to see the dealers finding here. Something sounds odd there. Please keep us posted.

dmhenderson · 04-09-2013, 10:59 PM

Fairly confident I didn't have anything to do with this UNLESS:

-Dyno pulls. I had quite a few while tuning the car. Would that do it?
-Abuse of synchrorev match while downshifting.
-Z1 silicone hoses weren't reconnected properly? This isn't likely though since there wasn't a clutch line - just a brake booster hose.
-Gremlins

Grasping at straws here.

Want to reiterate this wasn't a catastrophic clutch failure. I've seen first-hand what that looks like. This was odd. Monday, the clutch "stuck" down towards the floor a couple times but with no grinding/burnt clutch smell. Oddly enough, it would still engage fine but the friction point was almost on the floor. I fixed it by flipping the clutch pedal back up with my toe. I assumed it was just getting caught n the floor mats.

Drove the car home from work on Mon night with no issues. Parked and went to bed. Got up in the morning, and the car simply would not drop into gear. The clutch pedal feels totally disconnected. I could/can push it down to the floor (it sorta clicks) and pop it back up with my foot.

I have $10 on it being a leaking CSC but the leak wasn't crazy so you didn't notice it. I mean the **** doesn't evaporate. My car was delivered August 2011 so its 1.5 years old, I have 15k miles logged in it and is nowhere near low.

Just a suggestion... Ask the dealer if they have any GT-R brake/clutch fluid. It may be Nissan branded, but I think it is upgraded fluid over the Z. Just a thought.

Good luck!

dmhenderson · 04-09-2013, 11:28 PM

The R35 clutch fluid is what they put in the Nismo Z according to Nissan.

I've learned something today. Nice to have a NISMO! Good luck with the repair.

This is correct. Slave cylinder failure.

Replacing under warranty. Should have the car back tomorrow / early afternoon.

But if it's gone completely, there will be air in the lines when you add more, and that requires that you bleed the system. ( Click to show/hide ) And FYI, if you have the tools (probably not at your GFs place) and the confidence that with time you could do it (seems you do), I would think just about anyone who can follow instructions can push the pedal. If it's likely they've never done anything like this before, you definitely want to demonstrate on another car's brake pedal. I had my wife practice first on her Acura (with it on to make it easier) to get a feel for the speed, and explained that pumping too fast would cause air bubbles and set us back further and take more time. That got her attention since I already told her that her leg would be sore after we were done Oh and I use ATE Super Blue and ATE 200 (gold) and switch between them when I change brake and/or clutch fluids. It makes it easy to tell when you've cleaned out the old fluid It can't handle the heat quite as well as Motul, but it's better than stock and does just fine for braking during "spirited driving". __________________ 2011 370Z 6MT Sport Gun Metallic \| ARC \| CJM \| Ecutek \| FI \| Fujimura \| R2C \| SPL \| Stillen \| TWM \| Z1 \| ZSpeed \|
