My D/D has just over 100K miles. It's been very well taken care of. I'm about to do a DIY brake job, front & rear. I'm concerned about the rotors. They're in very good condition, but have never been resurfaced. I'm thinking about just putting on the pads, and foregoing the rotor turning, as they still "look good". Looking to the brain trust here, for experienced opinions. Many thanks.
