Do you even use your brakes? ;-)

With use, pad material gets transfered to the disk, sometimes this happens
uneavenly and the pad grabs differently at that spot because of the
difference in the coeficient of friction at that spot.

Now, I thought brake pads were the wear item, and the rotors should last
a while. Am I being lied to, or can 74000 miles wear the rotors down
that much? Should I measure the rotor thickness? What is the lower limit?<
It is quite possible to be so close to the wear limit on the rotors at 74K
miles that they can't be turned down without going under the limit.
Happened to my NX at around that mileage.
The minimum allowable rotor thickness is engraved on the outer edge of the
