I recently replaced the front pads of my 07 because of a grinding sound when breaking. I suspected that the pads were worn. What I noticed was that the inner pad on the driver's side was down to metal. But the outer pad still had about 0.25" left. Same with passenger side. Usually, this indicates that the caliper pins are seized. But although somewhat snug they were sliding ok. I relubricated them anyway.

Any thoughts on this? Thanks.
