Honda does recommend replacement of caliper bolts per event. I never have mostly because I can't ever find them quickly. I assume the threads stretch and the bolt weakens when torqued. Also FYI Honda specs RED loc-tite on the bolts not blue. Some guys actually use nothing in this critical fastener area.
A couple of facts. Honda's red threadlocker is similar to Permatex' blue. New threadlocker does not stick well to old hard threadlocker. A belief (pretty sure, but not positive). The caliper bolts are not stretch bolts. (If they are, by the way, not replacing them would be _really_ a bad idea.)
In my opinion, Honda wants you to use new bolts mostly because they know very few people would do a good job of cleaning the old threadlocker off, and applying fresh. I find it enough of a bear that I prefer to buy the new bolts.
In the good old days, before obsessive weight reduction and cost cutting, this issue was solved by simply substantially oversizing the caliper mounting bolts and the thread engagement. Cars still do that. We're left with smallish bolts and threadlocker, because the thread engagement isn't so hot, either. Wouldn't be so bad if you didn't have to pull them every time you change tires.
