Hello all, 2006 S60 2.5T, 170K miles. I've looked at the front brake pads, and it seems the ones on the passenger side have slightly more meat on them than the driver's side, maybe a millimeter or two. Is that something I should be concerned about, with one caliper possibly starting to go bad?

 

1MM is nothing to worry about. If it was 6MM+, then I would look into caliper replacement
