Ken:
The problems I have encountered in my Syncro with "smooshie" pedal have been
related to rear drum diameter; either adjustment, shoe thickness, or the
thickness of the drum itself.
I drove my self batty last year replacing wheel cylinders, shoes, flushing
and bleeding fluid, adjusting, etc. until I finally replaced the drums.
Once I did that and followed the *exact* specs in the Bentley for adusting
the shoes, everything was fine.
It seems to me that the design of the rear shoes is flawed in Vanagons,
making them particularly suseptible to this sort of problem - as the shoes
wear, they do not wear evenly, but rather the arc of contact with the drum
changes, since they only adjust in one dimension. (Some of you know what I
mean, and others are probably reading this saying "huh??") :-)
Try taking the parking brake up a notch and see if that makes the pedal feel
better - if so, I'll wager it is a problem with the clearance between the
linings and the drum...
