I was wondering with the disk brake upgrade kits for front and rear that are available, if anyone had determined if a larger master cylinder from another VW, or Audi vehicle would be a drop in replacement for the stock Vanagon unit.
(Or vacuum booster)

I've always thought it would be nice to have a little more mechanical advantage over what the stock unit gives you.

Now, what would be really cool would be if someone adapted an ABS system to the Vanagon.
