I feel for you. This is crazy. I have the same brakes and their performance is stellar.

Makes me wonder if something else is going on. Could it be a defective rotor hat that's flexing? I would think runout in the rotor ring would be obvious when braking. Replacing the hub is worth a shot.

It could be worse. I'm having chronic power steering issues. Last weekend I had to finish the weekend without power steering when my racks pinion seal puked. I think I have Popeye arms now...
