I just bought a car from a neighbor, it's a 2003 Lincoln Town Car with 79K, but I had to get it inspected before DMV would issue tags. The inspection station said the rear brake rotors where a 'little thin' and I told them to replace them and put the old parts in a box so I could look at them later.
Anyway when I check them out, I find that they have 5mm left before they reach the wear limit and the pads look to have about 30K/40K left before needing replacement.
5mm? You sure about that? According to
here, OE minimum thickness is .472" and with this particular part, the original thickness was .548". That's .076" or 1.93mm. The actual OE part may have been slightly thicker or thinner, but not by THAT much.
Regardless, you were likely were taken and upsold for a repair that you didn't need. In the future, unless you're having a complete brake job performed, or are experiencing specific problems with your brakes (and
"warped" rotors don't count) rotors generally don't need replaced, especially because they were "a little thin".
