Default WTH am I missing

OK, apologies for the Wrangler question on Cherokee forum but I value ya'lls input.
88 YJ 4.2 BA 10/5 trans. Thought the slave / throw out bearing was bad. Replaced that and the master cyl. Also new hard line from master to slave. Bled system several times now and does not appear to have any air bubbles. I still have little to no clutch pedal. I can pump it up and it improves some but only momentarily. Clutch certainly is not fully disengaging as the Jeep will crawl with pedal down in gear. Clutch plates and pressure plate are just over a year old and haven't got but maybe a couple thousand miles on them so I did not replace them...... So, WTH? What else am I missing??? I am all ears.

Not familiar with the BA tranny set up. Does it have an external slave?

Did the clutch suddenly "fail"?
Is the pressure plate intact?

It did. I drove it to work one day, about 60 miles and at a stop light it just went. I didn't pull the trans, I'm completing someone else's mess that shoulda never happened but I'm any event I did have a look at it but honestly I didn't inspect it carefully.

That was on my mind this afternoon though

I've seen this on a few other vehicles where everything but the slave cylinder was replaced and it was, in the end, the culprit. That's probably what's wrong with yours. It's the only thing left. When the clutch pedal is depressed fluid pressure is routed to the slave (actuator) cylinder which acts upon the throw-out bearing. If the slave piston seal is ruptured fluid is bypassing from one side of the piston to the other giving you near zero pedal feel and little to no clutch action.

He stated he replaced the slave , lm gonna say it still has air in the system they are very hard to get it all out. I have a reverse bleeder from Phoenix that sends the fluid in the bleeder and sends the air up and out ,this works much better than the other way
