Most of my parts will be here by Friday. The only thing that's left to do is to get some line wrenches. What size line wrench would one need for the Vanagon brake lines?

I am thinking about doing a video and/or pictorial.

11mm also known as flare wrench, IIRC.

Colin, you are a wealth of knowledge. Can't wait to buy the book! May I suggest digital edition, and wiki?

There is some brake fluid in the booster. I vacuumed as much as I could out of the booster, and the rest I soaked with a shop rag. I also sprayed some brake cleaner, and got it out too. Removing the brake booster appears to be a major undertaking. Should I spend the extra effort and get it out for a good rinse?

Nah, final hit it with something good for rubber/plastic parts, spray silicone? You want to displace any remaining moisture-attracting brake fluid that could quickly corrode the control valve spring and flake rust into the orifices. Too much cheap plastic in the control valve, can't use WD-40.

Looks good. Did you test "apply" pry the brakes to see that the actuator lever advanced the adjuster cog?

Was it really cheap cheap cheap metal that caused it to break off?

Very cheap stamped metal. The root cause of the problem was the PEX rear brake cylinder. It was not returning the pads, and was making this thing literally fold under the adjustment cog.

My vendor has come through and they are shipping the replacement shoes, and a new wheel cylinder. I'm shifting directions mid flight, and will be going with rear disk brakes. The kit is very very expensive, but it is going to be worth it.

Not so fast. Self-adjustment hardware can be ripped out of there, forget it! Manually adjust your brakes!
BUT
Rear disk brakes add nothing! to your braking performance, but they might add imbalance to the factory engineering, what is the story with how rear calipers will play with that lovely pressure regulator? Does its pressure release match the lock-up point for the rear calipers? Where are they made? Where do they attach to the wheel bearing/backing plate? Does this disk brake kit give you a new master cylinder? If not, verify that the volume in the rear chamber is matched to the volume and surface area of the rear disk calipers.
