As a matter of fact, no I didn't. I'm waiting to see if it repeats. I don't like throwing parts at things without understanding what/why. With the thing being mostly clean (very clean in fact) with that heavy bodied substance (much heavier than ANY normal contamination I've seen) globed around here and there in a pattern that defies my understanding of how it was dispersed, I want to see what it looks like after a short time. And with a seal leaking, even if it gets mostly slung off, their will always be a tacky residue that will build up over time. The seal surface was completely dry and clean. If it does it again, I'll replace the seal even if I can't make sense of it since that is the only place it could be coming from (unless there is a trans-dimensional doorway in there /forums/images/graemlins/eek.gif).
But if I replaced it this time, and never had another problem, I would always wonder if it was someone's misguided attempt to "lubricate the brakes". It's worth the extra pull down and a couple of cans of brake cleaner to find out for sure. I may even try to find a way to do rear disk with e-brakes and toss the "refreshed" over priced shoes in the trash where they belong...

Oh, and you mention the "wet" behind the spindle. Notice that it is a "clean" wet? That's there because we pulled it down a few days before the pics were taken but I didn't have time to clean it up, so we buttoned it back up to keep out dust and potential rain. The seal pushed clean oil back there from the spindle. If it were leaking enough to cause the surrounding mess there would be much more buildup there, at least as far as I can understand there would be...
And, while I'm editing, have you ever actually seen a brake assembly that clean with heavy globs hear and there? If so, then that may be my answer, maybe it's just a rare and interesting manifestation of the symptoms. But I've never in all my years of trucks, muscle cars, street rods, and so forth seen anything like this… Just "lucky" I guess.
