Never go to dealership to buy brakes, they were trying to charge me 300+ just to replace the rear brakes. I decided to just buy aftermarket and I ended up replacing both front and rear pads/rotors for $400+. You're much better off asking friends to see if they know a place that could do it for a fair price (installation). Not to mention the car brakes much better than OEM.
If you're looking for good brakes, I suggest check out EBC Brakes, I have them and will definitely buy them again. I did some research on them to see what others have to say and everyone gave it positive reviews.
