Slave failure without leaking?

I did a track day last weekend and towards the end the clutch started sticking to the floor. Was able to pull up and continue but had to pump it up. Was able to drive it home and get it in the garage but still have to pump and pull pedal back up. I tried ranger method hoping that would fix it to no avail so I pulled exhaust and tunnel plate and commenced to bleeding a full bottle through the system. Still have issue. So I tried vacuum from top and that didn’t work either so back under car tried bleeding again. Clean clear fluid is coming out but pedal isn’t getting better.

The slave isn’t leaking fluid at all. Is it possible the slave is shot and still holding all the fluid? Trying to decide best course of action before ripping the drivetrain out and installing clutch.

my guess is slave elastomer is probably shot, just not leaking Yet.
any access to it w/out dropping major components?

Negative, everything has to come out to access as far as I can tell. Which means time to replace clutch as well.

You have to basically pull the entire drive train from the bell housing back to K member to change the slave. The TT needs to be separated from the bell housing to get it out.

If it were me, I would replace the Master cylinder with a new stock master before I did the slave replacement. The master cylinders do go bad and the issue you are having can be contributed to a gummed up master cyl.

Thanks Bill, I will give that a shot. I wouldn't want to do a new clutch and not replace it anyway so hopefully it solves the issue.

I just went thru the same problem. Seems the general consensus is the clutch master cylinder being the culprit.
