I did run the shoes out until they were dragging a little on the drums.
Pulled the drums off and backed them down just a bit figuring the self
adjusters would bring them to where they need to be. There is still a very
slight rub when "spinning" the wheel so the shoes have to be close.
I am using the Bentley and unfortunately it only gives specs not procedure
so I am relying on my old mechanic ability but must admit to no VW or
Vanagon mechanical experience but I do have a decent mechanics background. I
used to own a body shop and did more than my share of mechanical work and
driveline swaps, even some custom work. I believe I have working knowledge
of basic mechanics but havent done any such for the last 15 years or so
other than "tinkering".
My bleeding preceedure is to start with the right rear and have help,
translates to wife, pump the pedal three times slowly. I work around to the
left rear then the right front and finally the drivers front. I even tried a
passive bleed where I open the bleeder them the pedal is pushed. I close the
bleeder and the pedal is released. No difference in either the pump or
passive method as to results
Under normal circumstances I would consider this action as a failure of the
master or "bleed by" in the master but as I said VW is a whole different
creature and I am staedy finding things that just dont work the same as on
the older domestic vehicles that I did work on. I enjoy the Vanagon and it
is/was my daily driver. As of late it is more driveway stationary art than
driver.
I will tear down the rears again tomorrow and double check but if I can hear
the shoes moving and gripping then releasing I am assuming that there isnt
going to be anything "jumping out" at me that I missed. I may try adjusting
the shoes up a tighter to a noticable drag and see if that helps.
Is there an adjustment hole in the backing plate to adjust the rears? I
adjusted them to the point of being able to get the drums on not with the
drums on because I didnt see any means of adjusting them after assembly.
Maybe that is the problem?? Can anyone offer the proper proceedure for
adjusting the rears? Maybe a page somewhere with detailed instructions or
pics/ It would be a help.
Thanks again ,
