I imagine replacing the bolts would not be cost prohibitively expensive, particularly for a safety item. That said, I replaced my bar ends, and the manual said to replace the mounting screws. Since the bar end screws are not under a lot of torque, and consequently not subject to fatigue, the only reason I could think of to replace them was that new ones have a fresh thread locking patch on them from the factory. I did not replace the bar end screws because they were perfect, and simply used some blue thread locker. So, perhaps this is the same situation with the rotor bolts?They are a single-use bolt which stretches a predetermined amount. Once used and removed, the bolt is considered unsuitable to put back in service.
I've replaced a bunch of these. I think I still have quite a few left over.
It'll cost about $20 to replace them, cheap insurance. Honda says to do it, I do it.
You COULD replace the bolt with a conventional, non-stretching type of the proper grade and size, but I figure Honda have a reason for using that particular bolt and when it comes to brakes, I don't like guessing.
Bar end weights, if they come loose, not likely to lead to a crash.
Brake calipers, probably.
