Clutch to the floor
Morning all. Last night when I went to start 1995 conv 6spd, my clutch pedal went to the floor, no resistence. I checked for fluid under car: none, looked around reservior. no leaks. Then I found washer on drivers mat. From FSM, looks like retainer broke or popped off or broke (about to start removing knee booster et al). I got a GM part #3817880 from a 2015 post. Not sure if I get get, but would a metal c-clip from ACE work? And how difficult to reconnect? Thanks for the help.

After the rain stopped, got seat out and knee bolster off, and to my surprise......rod was still attached. Then checked reservoir..........low and dirty (I bled it when I got the car in 2017). Since I'm lazy, going to use ranger method again, but slowwly depress pedal, hold for 5 minutes, slowly release, the pump 100 times, checking every 20 pumps to fill reservior. Lesson of story.............check all fluids every 2 weeks. Next job cooling system flush, been 2 years.

If you are losing fluid, replace the clutch master cylinder and slave cylinder now. The fluid run out inside the bell housing or the drivers floor boards and you can't always readily see the leaks (replace the hose too). The #1 by far cause of the ZF6 needing a $4500 plus rebuild is running with weak hydraulics. You already have the hard part done by getting to the pedal clip, please trust me on this one and replace the hydraulics. Nothing sucks more then a $4500 rebuild (yeah, it's gonna be $4500 or more) and then building a shipping crate and adding another $200 each way in freight.

Do your clutch and slave cylinder at same time, clutch hydraulic line too for insurance....they all leak. I just did all three, reverse bleed it with a hand vacuum pump with fluid reservoir attachment, was fully bleed without pumping!!!!

Update on slave cylinder replacement:
Got new one from NAPA and bleeding kit. Easy to get cylinder off bell housing, but it took 1hr and wd-40 to get hydraulic line off slave. Got hose attaced, slave back on and no leak from bell housing, and started to bleed................................... ........................and never stopped. The slave cylinder was leaking from the bleed screw when closed, and from the base of the bleed screw.
Looked at new bleed screw, no burrs on junk in threads. So I tried old bleed screw.........too short.
Part back to NAPA to replace, and so goes another Sunday. Starting this coming Saturday as soon as sun up.
