I trust Big Jim too, but WHY are the shims needed when they aren't there from the factory?
I don't understand how making the backing plate slightly thicker makes the pad quieter. Since the piston is self-adjusting I don't think that the pad to rotor clearance is any different with or without shims.
Seems to me like having a metallic "sticker" wedged in there is asking for trouble later on, since, again, they aren't there from the factory.
There must be a good explanation.
