How do you know whitch one is bad, Master Cylinder or Slave Cylinder?
97 TJ, my clutch will not disengage when you push it to the floor. the pedal still has some resistance when you push it down but you can feel it still trying to pull. Does this sound like I am on the right track with the master or slave cylinder or could this be something else? I don't see any leaks around the master or the slave and i don't seem to be losing any fluid from the master reservoir.
On my '91 YJ I had the same problem. The shop had to replace the Master and Slave cylinders because a seal was breaking apart in the Master and small pieces were lodged in the Slave and in the lines. If it turns out that you find any trash in either cylinder (tiny pieces of rubber seal) - be sure to flush-out the line between the two cylinders as well. Or - you will get to do this all over again in about a week.
Hopefully it's as easy as replacing the slave. If the slave isn't defective, the issue may be a failure in your clutch fork/throwout bearing.

I had the exact same problem...push the clutch to the floor and it will not let loose of the gear/engine. Does the clutch not want to come back up? I would push the clutch all the way down and not be able to get into a gear or out of a gear. Replace the slave and be done with it. Pretty simple process. If it was the throwout bearing, most likely the clutch wouldn't move at all. About a $50 fix...
