HELP! ZF-6 Speed Clutch bleeding problem.
I just replaced my master and slave cylinder on my '91. I thought bleeding would be straightforward. I've followed to book (open bleed screw, push clutch in, close screw, release clutch pedal etc.) My wife's leg is about to fall off from pushing. Tried using my Mighty-Vac. nothing seems to work. Seems the fluid level in the master stays pretty much the same :confused: Am I missing something? :mad

I dont know if yours is the same as my 86 but I had the same problem untill I pumped it 2 or3 times and pushed the pedal hard to the floor. I had to put some serious pressure on it before it would bleed. Get someone with a strong leg.It took a few times to get it, It also helped after I was done to pump the heck out of it , I dont know why but it worked. Good luck. :chevy

Here is how to deal with that problem:
1) Remove slave cylinder completely, take it to your workbench.
2) Leave bleeder screw tight.
3) Compress slave push rod completely.
4) Feed clutch fluid in as you slowly release clutch slave rod.
5) You may have to "burp" the slave just slightly, and/or repeat steps 3 & 4 a couple of times.
6) Once satisfied that slave is full of fluid and not air reattach to fluid line (which should be slowly dripping clutch fluid - don't let clutch master cylinder get low!).
7) Before reattatching clutch slave cylinder to the bellhousing you will want to slowly press slave rod - as you do so you (or your assistant) should see bubbles coming up through clutch master reseviour.
8) Repeat #7 several times, always being sure not to overflow reseviour as you empty air out of slave, feed line, and clutch master.
9) bolt slave back onto the bellhousing.
You should be good to go - now go lay some rubber!
