Yessir...spent plenty of time looking (wastefully, as it happens) for an aftermarket upgrade, and I'm truly surprised that there doesn't seem to be one. Z1 claims recorded CMC failures are so low that there's no market for it...but I find that hard to believe.

At any rate, the things described here about MC failures seem to sync up with my own experiences...things like on hard launch the clutch getting stuck to the floor with a redlining engine until pumped a few times...this only happened two or three times total over the last few months, but it did happen...and how when bleeding the resistance feel would build to a certain pressure near full release and then resistance would start to disappear.

Somewhere else a ZSpeed guy says ""Once you open the system, if the master cylinder is weak it will not work correctly." when telling someone why they recommended buying one with a CSC...something I'd wish I'd known.

I'm trying not to latch into this as my sole hope, but if it doesn't work I just don't know what else to think. My buddies seem to think this'll solve it, so I'm hanging my hat on it.

We'll see tomorrow!

Side note: today, my buddy's 370 CMC also crapped out. Not completely; he's still got enough travel room to grab gears and shift, but it's very, very weak compared to last night.

Something is in the air here

To be honest, my clutch pedal got soft a few months ago. Replacing my clutch pedal with the RJM assembly this past weekend seems to have made it more noticeable :\

I was expecting the CSC to go out first. I guess replacing the CMC is easy enough, I can do that if it really starts to bug me and the CSC is still OK. Or I can just wait until I need clutch/transmission work and replace it all. Or maybe I should start doing hard launches off the stoplight lines to help nudge it along toward failure

The CMC is certainly less trouble than the CSC. Had to remove two screws from the ABS that were in the way but that was probably the hardest part next to the Lin, which just seemed to be frustrating.

Might as well get it done, mate....before it goes all the way out. Don't play with fire.
