Clutch Pedal Issue - Was Broke - Now it works?

So, I posted earlier about my clutch pedal issues. It went to the floor and stayed there.

Well, I had a chance to get back to it and try some stuff.

1. Checked the fluid level. it was full.
2. looked for any leakage. none to be found.
3. Checked the clutch pedal itself. still on the floor.
4. Grabbed the pedal and pulled it back up. kinda "popped" and came right up.
5. tested the pedal a few reps, seemed to work.
6. Checked that the slave cylinder was working. it was.
7. started it up and tested it.... works just fine...
8. what the heck...

TLDR: it didnt work. I pulled the pedal up, now it works. Now what? Run it till it gives problems? or time for new master/slave cylinders? I have access to tools and a shop with a lift...
