Brake Fluid Leak
'98 XJ 4x4
Recently had my brake pedal go to the floor when attempting to stop. Had a brake line rust out over the summer and it reacted the same way. Today when I looked at it, I saw this coming from the left rear drum.
I added brake fluid which was empty and had the GF pump the pedal to see if fluid was coming out anywhere else. The brake fluid didn't drop and the brake light actually went off. I couldn't see it actively leaking from this spot or anywhere else. Thoughts?

You will obviously need a new wheel cylinder, and you might as well rebuild the whole drum while you are in there, since you have to tear it all the way down anyway. New hardware kit (with the auto-adjusters), brake shoes, and fluid. You also might need a special tool for #17 in the above link. I think I managed to get around the special tool, but I cant really remember how right now (memory is foggy).

Give them a thorough cleaning with brake cleaner, dry and repeat. Should be enough. Do the same with your drums. In fact, if that brake fluid has gone everywhere, do everything this way.

You should do both wheel cylinders. I usually do but didn't last time and the second one failed within a few months. Fairly easy job if you don't break your brake line/fitting. Soak the bolts and brake line fittings with PB Blaster for a day or two before you start, and use a line wrench (less likely to strip the fitting).
