Some very astute advice from Michael -- thanks. I guess another
reason why I am so inclined to turn the rotors on this particular
car is that they are "floating" rotors, separate from the actual
hubs. They basically are just discs clamped between the hub and
the road wheel by tightening the lugs nuts. Once the wheel is
removed, and the caliper is released (held only by two large Torx
bolts), the rotors will just slide off the lugs.
This makes removal much easier, of course, than with the rotor
cast with hub arrangement, and also one does not need to open the
hub (the hub remains intact on the spindle once the rotor is
removed) and expose the bearings.
I guess Chevrolet knew these brakes were high-maintenance items,
and gave us a "break" as far as removal and replacement.
