Well, I posted a question about whether the "small" or the "large" pad goes
in front on the brakes of a GPW....after finding the prior owner of my GPW
had one wheel set up both ways!

So far I have 3 votes for large pad in front and 3 for small pad in front.

Ron Cook quoted the Manual:

"Brake Shoes: Lining length-forward shoe (moulded)....10 7/32 in.
Lining length-reverse shoe (moulded)....6 39/64 in.

Installation of Brake Shoes and Linings. Install cam in brake shoes.
Install anchor pin plate on anchor pins; install pins in brake shoes,
and mount assembly on brake backing plate. NOTE: Forward shoe has
longest lining.(this in italics) Install brake return spring, and remove
brake cylinder clamp. Install brake anchor pin lock washer and nuts.
NOTE: Turn brake anchor pins so that punch marks on ends are toward each
other. Do not tighten anchor nuts.(this note also in italics) Install
hubs.(pars. 128 and 141) Make major brake adjustment (par 149b)."

It seems to me....being a novice at drum brakes (disks are so simple)....it
all seems to hinge on what is meant by "forward" and "reverse". Is the
"forward" shoe mounted "forward" or does "forward shoe" refer to the shoe
that does most of the braking when the vehicle is actually moving forward?
The use of the terms "forward" and "reverse" in the manual seem to imply
vehicle direction rather than position on the wheel....thoughts?
