I'm wondering.......my 08 Rabbit gets a lot of dust on the rears, NOT so much on the fronts. The braking is very flat, very little dive, and also has brake-assist like the newer MBs. I'm wondering if there is some sort of difference in the way brake pressure is applied on these newer German cars, i.e. more pressure applied to the rears or something, to prevent dive, or since the rears stay cooler......it's just an unusual and increasingly-common characteristic of the newer cars
