I'm getting quite a lot more brake dust on the rear wheels than the fronts, not noticed any dragging or lock ups from the rear under braking, although I don't drive it in the wet, it's even dust across the rear wheels and driving it I don't notice anything wrong, and there may well not be, but it just seems odd. I'm sure it's the normal front \ rear split with no bias valve but is there a valve that loads the rear brakes when the car is lowered to compensate for heavy boot loads, towing etc that might need adjusting? Anybody else noticed heavier rear dust?
