Walt - that kind of shimmy usually indicates warped rotors rather than a problem with the calipers.

I'm almost to the point of putting the car back on the ground, but I've noticed that both my new rear rotors appear to have around 1mm wobble inside the calipers. This seems to be excessive to me, but I would like to know anyone else's opinion. Question 2: Will moderate rotor runout cause premature wear to the calipers? Before I took the system apart, I had an annoying amount of steering wheel shake as I applied the brakes.
