found another source for brake pad knock back! I swapped rotors and got a piece of crud sandwiched between the face of the wheel bearing and the face of the rotor. Looked like a small ball of rubber that fell from somewhere in the wheel well as I was swapping. Was enough to increase the runout of the disc. It also gave me a little funky pedal feel.

After cleaning the two faces and back together, very little runout was measured and pedal back to where it should be when braking.

From now on I'll check these surfaces and scotch-brite them during rotor swap
