Anyone else ever run into a problem where their rear brake pads wore
out at 14K miles? I mean all four worn all the way down. This is not
an issue with one side of a caliper hanging, nor did the dealer find
anything wrong with the calipers.

It's my wife's car and she does do a lot of city driving but the front
pads have hardly been used (10/32" remaining, new pads measure between
11&12/32") and the rear ones are shot. The dealer I took it too turned
the rotors (under warranty) and replaced the pads (at my expense of
course) and said they didn't see anything mechanically wrong and to
bring it back in another 3-4K for them to take a look at it.

Looking for any info I can relay to the dealer to tell them to look for
if anyone has come across this problem. Any help would be appreciated.

Thanks!
