If you look at almost any vehicle that has air brakes you will see that those brake shoes work the same way. Fixed at the bottom and the actuator and adjusters only work at the top. Air brakes usually start at 26,000 pounds.

The rear drum brakes on MY van..an '84..they are laughable. First time I looked at them, I was amazed..."This is how it was sold?" I thought. The brake shoe mechanisim in the rear hub reminded me of what you might see on a stagecoach...except the stagecoach ones must have worked better with just a single 'center'.rather than pretty much pivoting on one end and moving only the other end.... I bet you can find vanagon rear shoes with linings that are untouched on one end and worn to steel on the other. They do help stop the van, I guess. Musta been a Friday when the VW engineers sent in that design to Managment..I am not complaining though..they work. If I lived and worked somewhere involving a commute through the mountains or over a pass, I guess I'd swap them for something different, a set up that actually used the braking surface that you pay for on the shoes...
