In my 89 yj Installed a 5.3 with nv4500 external slave, used stock master cylinder, 93 plastic external slave, bled the lines, drove it, 2 days later I have no clutch pressure, fluid just moves up in the cylinder when you press the pedal down, and I've replaced the master slave and line already

If yoiu have fluid rise on pedal press and release, your used master cylinder is most likely no good.

I got it last night, both brand new master cylinders I put on where junk, used one I found in the spare parts box from building my nova, speedway master cylinder worked right away barely bled it,
