I'll back up Dennis on this one.  The spring inside the wheel cylinder
is only on the ATE/FAG/FTE cylinders outa Europe these days.  Brazil
TRW/Varga and the Far Eastern variety don't have the internal springs.
 This spring is absolutely necessary for the Vanagon rear brakes to
work properly and its for this reason I tell the sales guys at
Airhead/VWG to only sell the OE cylinders for a Vanagon application.

The TRW/Varga variety is OK for the 72-79 Bay Widnow because of the
slightly different design in the shoe operation.  Of course, I stay
away from the Far Eastern variety because of fluid leakage and poor
metal line connection seating.  I speak from personal experience.

My nickel's worth....
