Slave Cylinder

[jeveretts]

Recently, I had what sounded like a clutch release bearing go bad in my '02, there was also a weird dead spot in the pedal on the way back up around 70% from the floor. This weekend, I pulled the tranny, replaced the RMS and the IMS Seal and O Ring, I put a new clutch kit, plus actuating lever and hardware in. Everything is working fine, but I still have the weird dead spot. The clutch engages right as the pedal starts to come up from the floor, but at around %70 up, it just goes kinda slack. We have bled the crap out of it to no avail. Could this be a slave or master cylinder problem?

Oh, I also found some weird stuff when I took the old clutch parts out, one side of the release bearing was worn way causing it to go cockeyed in the release lever, eventually making the release level come in contact with the pressure plate arms.

I've never seen a bad slave cylinder do that - but there is always a first

I would look for a bent cable arm on the transmission.

You mean a shifter cable? if so those looked fine, and shifting is still butter smooth. I might add that the car is driving fine, just crappy slack at the top of the clutch pedal. Almost feels like the slave plunger isn't coming back in all the way.

Could be the clutch pedal assist spring unit (if still present), the wrong clutch assembly (3.4 L versus 3.6 L / S - 3.8 L), missing plastic top on the slave push rod or bend, and still air bubbles in the system (your profile shows Boxster??)

we did match the clutch parts by number. There is a rubber boot over the slave arm. I don't know about the spring, when we were bleedin the pedal would have to be pulled off the floor after opening and closing the bleeder. I also bet that there is a proper way to bleed this, we were doing it just like brakes, pump a few times and hold, open and close the bleeder, pull the pedal off the floor, repeat.

Just to close this one, I put it on a vacuum bleeder this morning for a few minutes, and ran about a litre of Fluid through, %100 perfect.
