Over the past two years, I have replaced the rotors 4 times including having them each cut 1 time. I have also replaced the calipers twice and the rear drums once. My rotors have warped again and I'm looking for a solution. I have 246,000 miles on the car, my driving habits have always been the same and this has only just been over the last two years. I also do mainly highway driving with minimal traffic so i don't even have to brake too often.
