No idea, only that BMW say replace them. Would have thought it's a stretch consideration.
I know Honda do the same thing on some of their bikes too.
I think because micro encapsulated screws should be used only one time!
I don't think 24Nm could stretch the bolt of this size and for sure if you thinking to use them again threads should be cleaned properly and correct thread-lock applied
Question is should we risk brake failure for only £4?
