I purchased my 2005 Mazda 3S during the winter of 2005. For the past 4 years I have religiously had my car serviced by Mazda dealerships consistent with the recommended servicing schedule. Despite this, my rear brakes suddenly ceased Monday. After having my car towed to a Mazda dealership, I was informed that my rear calipers and brake lines had completely rusted through and that they must be replaced along with my rear rotors and rear brake pads - for $2650 (not including the towing fee). My car has less than 38,000 miles on it and was always well-cared for. It raises serious red flags that such an important element could completely corrode in such a short amount of time. In my experience, in cars with much more mileage, I've never encountered such a hazardous mechanical failure.
