I bought my new M3GT in October and have been driving it in light snow as of late. I have noticed that the brakes REALLY grab for a moment when pressing them after going through deeper snow. Is the snow/ice getting int he way of my front brakes? Is there a safe way to "clear" them while in motion? Or are my calipers sticking? The pedal thumps a few times and sticks a little and then clears up... But so far as I can recall, this ONLY happens when there is deep snow or heavy freezing slushy ice...
