Drum brakes help

[topher5150]

I need to the back brakes on the man van, I think I got most of it figured out, but I keep seeing things on the interwebs about some adjustment wheel. Does anyone have any knowledge about this, and maybe some pics too???

"Man van"...is that like "man boobs"?

Check out the self-adjustment section here:
