That's great news!

Once air is trapped in there in can be difficult to get out, but it seems like the reverse bleed did the trick.

Well, I've driven around some more, and I'm not exactly sure all the things I'm experienced are to be considered normal.

In a 20 minute drive, I experienced minor clutch slip under near WOT. It went away after about five minutes, although it doesn't quite feel exactly the same. Of course, just the fact I thought I felt slip probably predisposes me to think everything is wrong.

The clutch engagement has changed remarkably. Unlike before the issue came up, the entire pedal has pressure (minus the first half inch; still no clutch helper spring). Before, it was kinda floppy for the first inch or two. I guess it's to be expected if there was air in the lines. However, it engaged along the rest of the pedal travel. Now, the engagement is only in the first inch or two after the half inch of play. Everything afterwards is just as stiff, but does pretty much nothing. I can easily disengage gears without even pressing the clutch halfway down. It reminds me of the first few months of owning the Z, except I still had the stock helper spring.

So, I guess what I'm asking is, assuming the flush was either completely or mostly successful in removing air, what can explain the symptoms?

I am also more curious about running ZSpeed's CSC and the Southbend steel flywheel. Any issues in that set up with the OEM pressure plate and clutch disc? I can still confidently say I am going to have the HD CSC installed.

Class action law suit against Nissan in regards to the CSC!
 

Folks, It has finally happened to me and after an exhaustive session with Nissan local dealer and Nissan USA, the result is me putting in the Z1 Motorsports option.
While that is going on, I have currently contacted a lawyer to look into starting a Class Action against Nissan for manufacturing, installing, and allowing this part to fail more often than not and knowing it. As one here has said "The dealership carries extra on hand because of this problem"...not completely verbatim but you all get the point.
What I want is everyone to pm me their story and I will include it in my hopeful interview with a local channel...maybe get some traction on this. Although many of us here can drive manual cars and if a failure occurs, we know how to get ourselves out of harms way, there are still many who do not if they loose clutch pressure, like my lovely wife. So yes, this is a safety issue.
I also encourage all of you who have dealt with this to also contact your states Attorney General and the CFPB (Consumer Finance Protection Bureau).
We can do this folks. We need to be reimbursed and then some for a known fault in the vehicle we love to drive, at least I do!

Keep us posted.
