Richard,

Fortunately, on my '84 you don't have to remove the calipers to replace
the pads.  I guess VW "improved" them with the '91's.

When it comes to brakes, especially the marginal Vanagon brakes, I don't
cut corners or cost anymore, it just isn't worth ANY risk.  Go to the
dealer and buy the bolts, even if they are $5 each and you have to beg
or borrow the money.  Do it right, do you think a top notch professional
mechanic would re-use brake parts the manufacturer says to replace?  If
you are going to do your own maintenance, do it like a pro!

Stuart, off soap box now.
