It’s a fair point, I’m assuming it’s warped because the sound and vibration is only happening under braking and coming from that corner. Rotating the wheel by hand encounters variable resistance similar to what I would expect if the rotor were warped. The wedged pads were from the fronts.

I do intend to pull that hub this weekend so we’ll see how that looks regardless but I think the rotor *is* warped also.
