My dealer says I need new front pads and rotors and that the job will cost about $500. I have looked at the front rotors and the wear on them is trivial. The pads look like they need replacing though. I looked only at the outside of the rotors assuming that the rotor wear rate is even with that on the inside of the wheel. Can anyone tell me what the recommended thickness is to replace rotors or should they be replaced everytime the pads are changed.
