This is exactly why I build relation ship with one service guy at my Lexus dealership...I always go to him and when it came time to do breaks i felt very comfortable with his evaluation. the front rotors were visibly too far gone and by measure. when they did the inspection on all four corners they sugested replace front rotors and just surface the rears....there was never a maybe this maybe that. so yes they can be surfaced but I myself went and bought front and rears pads and rotors centric and stoptechs and had them all done at the same time and did the braided line then also. I also always request the parts that come off the car. when you say this to a technitian they are more likely to be upfront with you on what needs done. they dont want you going and having them inspected, getting a differnt answer and then raising hell when you come back to the dealership.
