[s-cars] front brake research continues

>From my old engineering days, Aluminum has a finite fatigue life. Period.
Ultimately,
you cannot provide enough over design to keep it from failing, which is why
airframes on
aircraft are ultimately totally rebuilt (in effect) throughout their service
life. Steel CAN be
designed for infinite life. The question is (and I no longer have the tools
and time I need to determine this answer) what is the service life of the
aluminum brackets, and our aluminum wheels for that matter?
