Good runout (+/- .001 inches) does not necessarily mean there is nothing
wrong with the rotors. I have had pulsating brakes with true rotors that was
cured with a mild turning of the braking surface. I still don't know the
exact mechanism of the problem, but it has something to do with an uneven
drag around the rotor surface.
