just had this taken care of yesterday. Tried pulling back the heatshield a little to get it out, but nothing came out. Put it on the lift and it was still there when you spun the wheel.. took off the wheel to get at it more, and suddenly the sound was goneľ spinning the rotar didn't replicate the sound and nothing came out besides some dust. Took off the rotar just to check and there was nothing there, but were some marks of wear. Now the sound is gone.
