I pulled apart the rear brakes on the Fusion today, since they had some issues sticking. I cleaning everything and applied some moly/PTFE grease, and all is well. However, I did notice that a shim on one of the pads was a little bit 'loose'. This style of shim has the crimped metal fingers that wrap around the metal portion of the pad, and is by no means going to fall off. It was just the slightest bit loose. Pads are only 5 months old, FWIW. Should this worry me? Brakes work great and make no noise. I'm pretty sure I've even seen shims a bit loose when pads are new, but I can't remember.
