Z1 CSC Elim Kit Issue?

[batboyvaj]

I had my dealership install the kit. The master cylinder was changed as well. It seems clutch pedal has about 3 inches of dead play before there is some pressure in the pedal.

I checked the clutch pedal stop at the cruise control switch and it looks like it's adjusted to maximize pedal travel. Do you guys think there is still air in the line? The pedal doesn't feel spongy, but just alot of dead play.

You need to check both the spacing on the arm as it enters the transmission and adjust the washer stack down there as well as adjusting where the clutch pedal engages the Master Cylinder arm.

There could also be air but it sounds more like an adjustment issue.

I had the same exact problem when I put my zspeed CSC kit on. Don't drive a long distance lol I drove for an hour and a half and had my clutch go straight to the floor. I had to get towed to a dealership. I took it to a different dealership after that and they told me that the CSC was broken during install. It kept sucking in air. I finally put an oem CSC in after having my car in the shop 4 times in a month and it's been fine ever since. But there's also a possibility that there could be air in there still as well.
Go search: Need help with a clutch problem!
That's the thread I started when I had that problem and you can see what I went through. It might help. Hope everything gets sorted out for you and good luck

Could it be the stack height on the pivot ball. But the pivot ball only effects whether or not the fork contacts the tranny housing right?

If I lower the pedal travel to make up for the dead play, then my pedal would be way too low. There has to be some play somewhere else in the system. I'll have the dealer check the slave cylinder length.

One thing I notice in the instructions is they specifically note to switch the bleeder valve fitting and the line fitting from the way they come from Z1. It's at the beginning of the 2nd paragraph in Step 9 in the instructions I got.

The only thing I can think is this puts the bleeder valve at the top of the cylinder. If the bleeder valve is on the side, like it comes from Z1, then there is a pocket of air trapped in the cylinder that may be incredibly difficult, nigh impossible to bleed out. Its a very small amount of air that could be accounting for the dead play in your pedal.

If your dealer missed this, it could be your problem? I'm no expert by any means. I have no idea why Z1 would ship them with the fittings install in the reverse of where they're supposed to go.

Good point. I'm heading back to the dealer today to readjust the slave. I'll check this as well.

FIXED! There was another 3/4 turn or so left on the slave to seat the throw out bearing closer to the clutch "fingers". This and another bleed got rid of most if not all of the dead pedal.

Did shortening the overall length of the slave cylinder accomplish this?

Cool, give it a day or two and it should get better.

I'm pretty sure they had to shorten it. don't quote me on that though
