I did try to do what you said first - that is, I adjusted the cable with
the drums off - but I had not yet set the position of the shoes yet...
so when I put the drum back on, the parking brake had no effect. I
pumped the brakes a couple of times, but even after that, I was able to
remove the drum easily without backing off on the adjuster, so the shoes
had not expanded far enough. Maybe if I had kept pumping the would have,
but I had to turn the adjuster wheel at least two full revolutions to
set the shoes in the right position - so they were way off. After that,
I just adjusted the cables until they did not impede the free rotation
of the wheel when the brake was off, and stopped it when the brake was
on. I did that with the drum on.
My cables both slide freely, but, again, the angled ferrule that is the
rear cable stop is just held against the backing plate by the tension of
the cable. On the other two vanagons I looked at for comparison, the
angled ferrule seems like it is snapped right into the oval hole in the
backing plate... and for the life of me I cannot see how I could get
that to happen.
I'm not dis'ing drum brakes :) It's just that disc brakes always
seemed a lot less mysterious - more like bicycle brakes - and any drum
brakes I'd ever tried to mess with were a rusty mess!
