They are as thick (maybe thicker) as Vanagon front pads. The cylinders
do not look smaller than Vanagon front calipers either. I did not get
an impression that the pads are thinker and smaller. Of course I have
not touched the front brakes yet. So I have no idea how they compare
betwqeen the front and the rear.
Passat has many different brake systems according to Bentley. They
use different calipers and pads. The one in my Passat may be not the
one you are talking about. I tend to think that because of ABS the
brake system is very different from conventional non ABS systems.
Traditional brake systems may want the front to have more stopping
power due to weight distrbution. With ABS they don't want any of
the four tires to skid. It would not help to achieve this simple
goal by putting more stopping power to the front.
