Hi ,
I am tempted to give you a hard time about using 'all new parts.'
I would *never* do that !
I replace worn and tired parts, and keep all the ( often original and
perfectly good ) serviceable parts.
on the adjuster bar and wheel...
first ...I have never seen anything wrong with a used one ...( on a
hundred vanagon rear brake repair jobs ) ...heck, if was hired to
straighten this out, I'll probably put the original ones back in, AFTER
looking at a working vanagon to see which way they go in there.
Are the threaded rods on the correct side of the van ??????
the bars fit in two ways ...you'll notice at the end where the ratchet
lever is ..the flat end of the bar is wider on one side of the notch
than the other. Only one way is correct as far as I know.
you can barely see that in Bentley.
'what you coulda/shoulda' done is just do your worst side with 'all new
parts' ...until you had it working really right ..that way you could
look at the untouched side to make sure you got your new side together
correctly.
really man ..I can't say it enough ..
replacing Too Many parts at once easily leads to problems.
I speciallize in doing 'just the right' thing ..
I also don't have a goal of 'i don't want to look in these rear brakes
for at least 5 years ' ..
it's fine with me if I do say shoes and wheel cylinders and check
roundness of the drums ..
and get a year or so out of it.
I think it's good to work on things now and then, as that keeps things
from getting rusted and stuck ..
keeps you inspecting things etc.
Racing cars and motorcyclies are worked on constatnly, like before every
weekend ..
don't take things apart Too Many times...but 'some' is good for things.
'something' must not be right it would seem ..
incorrectly installed part, parts that are not truly correct, etc.
I don't think I've ever had the kind of problem you're discribing ..
but then I don't replace EveryThing either ...just the parts that need
to be replaced.
let us know what you find.
I'll look at those adjusting bars ultra, ultra carefully ..even put the
old ones back in.
you don't have to remove the shoes to 'sneak' other parts in ..like that
bar or even wheel cylinders.
good luck.
