no no.. not refering to the springs.. but to the bolts that physically attach the caliper in place. Its probably not entirely necessary to replace them, but, when we're talking about brakes, I guess one can't be too careful. I've reused the springs and other hardware several times.....whenever I've replaced the pads. But I've never removed the caliper, and my research just indicates that you should replace those attachment bolts, due to them stretching and weakening from torquing. Porsche recommends changing them with each caliper removal. hmmmmm Does Porsche make a lot of money on parts? of course. Is it absolutely necessary to replace them? probably not. Would I feel better if I replaced them? sure. (I know they're only torqued to 63 lbs, and the stretching of this bolt would be insignificant, but still.....)
