He said he checked the master cylinder already. If your master was on her way out, then the clutch would be 'sticky'. When you depress on the pedal it will stick to the floor for a brief period of time before disengaging.

Op, there is a nipple on the 2nd of the slave cyc. Open it. I think its a 8mm bolt. Dont open all the way just enough for fluid to leak.

Bleed her, like you bleed ur breaks.

Constant depress and let go till there is strong shot coming out the nipple.

You have to the tighten the nipple while your depressing the pedal. So 2 man job.

Refill fluid.

See if this helps.
