Inner workings of rear caliper?

Someone once posted a really nice diagram and explanation of how the self-adjusting mechanism in the rear calipers works. I'm looking for it myself, but if someone happens to know where it is or has bookmarked it, I'd appreciate a pointer.

Yep - that's it! Many thanks, and I would have found it a lot sooner if I had remembered who had posted it.

Now that I've found it again, I'm going to link to it from the wiki.
