My Sport is 4 month old and has already rust on disk brakes.
I've notuced disk brakes on my neighbour's Audi A 6 are pristine, and the car is 18 months old.

I've read this :
"Replace your stop rotors with ones which have special plating or cloaking similar to zinc or cadmium. Zinc might be the improved choice as cadmium contains poisons which can wear down onto the roads and can presumably means environmental problems."
