My buddy runs a small shop over in Kissimmee and had the same kind of thing happen with brakes. He'd been checking pad thickness forever and felt like he had it down cold. Then an old timer walked by and asked why one side was wearing faster than the other, turned out the caliper slide pins were sticking just enough to drag. He said it was like someone flipped a light on, he'd been looking at the pads and missing the whole reason they were wearing wrong. Now he checks the pins first every single time. Funny how one question from someone who's seen it all can undo years of autopilot.

Picture my uncle quoting Tony Soprano at Thanksgiving and suddenly the whole family got real quiet about who's "in the family business." Grandma quoting a Nordic villain is way more unsettling than any mob boss line though, honestly.

Classic Phoenix mistake. Wet it down or wait till evening.
