As I recall, the spring across the plate between the shoes was upside down
and would bind, also I believe I had the plate backwards. The Bentley does
cover this but the diagram is not exactly clear on re-assembly. Once that
was corrected, all better.

Hello,
I also had a problem with incorrectly assembled rear brakes. I purchased my
Vanagon thinking it needed brakes because it had a bad pedal feel and
marginal stopping power. However when I got it home and saw good pads and
shoes, and good hydraulics I was stumped and took it to the Van Cafe. They
found that the back brakes had been assembled incorrectly and fix the
problem.
