In 2014 I left the car parked outside in New England for 10 days when I returned the brakes were completely rusted. I took it to the dealer and had all brakes replaced. This month April 2015 car sat outside for 15 days and when I returned the brakes were locked. After 3 tries they broke loose so I could drive the car. 5 days later the brakes stopped pulsating and the rust build up pretty much was cleared up. Dealer can't explain how this happens but it is pretty bad when a car that is made to withstand Swedish Winters can't sit around in New England without developing major issues. I would like to know how to prevent this other than to just not to leave it parked outside for more than a week in the winter.
