Haha, thank you for the clarity. I knew the brake setup well enough but that you were inferring that gunk could've pooled somewhere and unbalanced it somehow. It happened to my sister's Audi when she got snow stuck between a few spokes of the rim and it was enough to make her car shudder. Thanks again for the guidance!Ok....The rotor is held in place with the lug nuts. and is sandwiched between the hub and the wheel. An uneven surface on the wheel, front if the rotor, back of the rotor, or the spinal all being held by the lug nuts. Can cause the rotor to warp, once they are warped there is nothing you can do except replace them. make sure all your surfaces are clean and true.
I didn't want you to think you clean up the back of the wheel and it will go way. LOL that is not the case.
