The pressure plate requires *a lot* of force to depress. I really don't see how a little spring in the pedal itself can aid in pedal return.

I suppose in some applications there's a port in the MC to aid fluid pressure equalization as the clutch fluid expands/contracts. Are you suggesting this may cause pressure to be applied to the slave without any pressure on the pedal itself?

The port in the master is closed as soon as you even touch the pedal, If the pedal does not make it to the full up position it will not be able to release fluid to the reservoir, It may not hold a lot of pressure in the system but can hold a little. Plus you are never getting a fresh load of fluid if it never gets returned all the way which can cause fluid to get hotter than needed and also will just use the same fluid in the line over and over and over.

Yes the plate returns the fluid which pushes the pedal back up but it is pretty obvious if you remove the spring it does not come ALL the way back up which is why your cruise control will shut off on you when you hit a bump with out it..

I went with the Z1 kit just because I use them a lot for parts. The clutch works and feels great now.

Well can add me to the list now. 2009 with 82000km

I'm thinking about trading my '03 350Z in for a new 370Z, and I'm researching potential problems. Sorry, but I couldn't read through all 108 pages of this thread. Am I correct that Nissan's solution to the CSC failure is to replace it with another CSC with the same failure issue? And the best option is to do a CSC delete on your own dime?

This just happen to me as well. Currently waiting for my z to be towed to the Nissan dealership. ��

brando_32 · 10-15-2016, 06:17 PM

Well the car is sitting at Nissan waiting to have the CSC Delete from Zspeed installed. I'll give an update once I get the car back. Big thanks to Joe @ Zspeed, great customer service and great to deal with!!!!!

Don't you have reputable techs other than from Nissan dealerships?

brando_32 · 10-15-2016, 08:25 PM

Small town, we don't have anyone that I know of to work on it. Most small stuff I just do myself.

I'd watch them with an eagle eye as they're doing the install...

A couple of weeks ago, I noticed a burning smell coming from the front of my Z. I check the oil regularly, so I checked it again, and the level was fine. There was no liquid on the ground wherever I park, so I looked at the rest of the fluids. The clutch fluid was below normal. I drove around for a couple of days, and checked again. The fluid is even lower.

The clutch feels fine, but I don't want to chance it. I'm assuming this is the CSC, right? The car is officially parked for the winter, and I'll be accumulating parts over time. I'm looking at the Z1 CSC Delete, a new clutch and flywheel, and a new master cylinder for good measure. Hopefully I don't get stranded on the way to the shop come springtime.

Edit: My Z is a 2009 with 42k on it.

Well I'm another one. My dad just gave me his baby a 2010 370z Nismo with 10k miles. Clutch pedal started sticking, stopped by dealership as also needed to get the steering column lock recall taken care of. They replaced the fluid with GTR as they said that usually solves the issue. When I got in, the pedal was still stuck on the floor so obviously it didn't work. I want to fix it the right way so wanted to see if anyone out there has recommendation for a place near Puyallup / Tacoma / Auburn ... Washington. I guess I need to get the CSC and master cylinder but not sure what else should be replaced while I"m into it. thanks

What exactly happens when the CSC fails and how exactly does one react to it? Obviously the pedal sticks to the floor, then what? I can only imagine driving down a highway then you try to shift when the clutch doesn't come back up. So now you are stuck in gear correct? Do you just pull to the shoulder and coast until the engine drops low enough in RPM to stall? I'm a little confused.
