Did I ruin my slave cylinder?

Hello everyone, I've searched, read, and read some more but couldn't find my exact problem. I had a bit of a jerky clutch pedal where it would be "sticky" and stop a bit then suddenly jerk up when bringing it back up from being depressed, I read that it could be caused by air in the lines. So I took my slave off to manually pump it like I read about 20-30 times manually to get the air out, that all went fine but I must have not lined up the slave cyl rod with the clutch fork when reinstalling. I got back in the jeep and pressed the pedal and it went straight to the floor with no resistance whatsoever. Looked underneath the jeep and saw fluid puddling on the ground. Took the slave back off to find the rod AND piston had come out and was leaking fluid.

My question is, can I just push the piston back in and re-fill/bleed the system again or did I ruin the internal seal of the slave and now have to get a new one?

ANY help would be appreciated. Than you. 2003 TJ 5 speed 4.0L

Clean the rubber seal on the piston with clean brake fluid and insure cylinder is clean inside and rinse with fresh brake fluid the carefully reinsert the piston while seal is wet and lubricated with brake fluid and you should be ok

Appreciate it, put it back together and bled it, all is well. Smoother than it has ever been. One weird thing though, the clutch used to engage about half way up before this, and now it engages almost right when I start letting up on the pedal, is that normal?

Another source of sticky pedal can be the plastic bushing where the master cylinder rod attaches to the brake pedal. They can break leaving pieces to bind up the pedal action.

The TJ's clutch is not adjustable.

So I am assuming it still needs to be bled since the TJ's clutch is not adjustable?

Thanks for all the responses this far, much appreciated.

Well... I just took it for a drive to the bank, back to being horribly jerky/sticky. Checked the bushing and greased it as well... No luck

Probably a little late now, but according to the FSM the clutch slave cylinder, master cylinder, and interconnecting line are meant to be installed/serviced as a unit. I know that you can purchase them separately or complete. When I had hydraulic issues with mine, I wasn't sure whether I had slave or master cylinder issues (and I figured both had 130,000 miles of use) so I bought the whole enchilada, and it came with new fluid installed in it and pre-bled. All I had to do was bolt it in. If I had it to do again, I'd do the same.
