Sanfelice, why are you turning your rotors? If just for cosmetic reasons then DON'T turn them. If for a warpage problem or thickness variation then possibly a very light cut. If turning for wear lines or slight scores just leave then as the new pads will soon conform & work properly.I have not yet measured the required thickness but I think I still have enough meat there to do this. Any advice before proceeding?
several years ago I had a pulsing front rotor on my '78. I knew a shop that gound them down and had it down (within specs). It has worked great since. As I understand it, the rotors do not "turn" correctly and end up worse, which is probably why honda recommends againt it.
