The thing is, I have a bunch of old shop manuals from previous bikes (Yamaha, BMW and Harley) and I also looked at online owners manuals re wheel removal and none I looked at recommend changing these bolts. Everyone says to change the rotor bolts and I get that. The Caliper bolts, I don't find that recommendation elsewhere.I think pretty much all motorcycle manufacturers recommend replacing the bolts, doesn't matter if they are hollow or not in that regard. Just another safetycrat safeguard that is totally unnecessary. A bolt tightened to 14ft/lb, 18ft/lb or whatever these are will never come loose. If they break during installation, replace, but that isn't going to happen either.
May be the recommendation is geared towards Honda mechanics at dealers. Possibly if they forget to tighten the bolts, the new bolts with the thread locker will retain the bolt and it won't fall off.
Like so many things regarding this bike this is just another thing I would really like to know the why of. So..you Honda guys lurking on here fess up!:grin2:
