3 years ago I had my front calipers, rotors and pads and the back rotors and pads replaced. I took the car back to the place that did the work because the brakes were grinding and they are saying that all need to be replaced again. This car has barely been driven, less than 6,000 miles in three years. They said the parts went bad because the car wasn't driven regulary. I have another car that isn't driven regulary either and have never had a problem with the brakes. Does anyone know if this is true. I just think $900 every 3 years is crazy. Is it possible that they somehow installed them wrong causing them to go bad so fast. If so how can I prove it? Any advise would be greatly appreciated.
