I never want rear discs again in the snow-country of the Northeast- have had two different vehicles- one domestic, one foreign, totally self-ruin their rear brakes in under two years, from new, with only me driving, and using a gearshift to decelerate, because of the way that winter salt get in the rear calipers and make them stick. Wrecked not only pads but rotors, and in one case, one of the calipers. Front discs don't seem to get the road slime up into them- have never had the same problem, nor have I ever had any trouble with rear drums.
