How often do you replace your rotors?

[dbazos]

Rotors are replaced based upon their remaining thickness, or if flaws or damage is found. Check the maximum wear limit for your car and if the rotors are getting close, I would replace them.

Used cars have used components on them. Nit picking brake rotors is BS. I have a lip on my rotors and I have 36K miles on mine and I'm nowhere close to changing them out...maybe turning them to clean them up but that's it. If you can, use a vernier caliper and measure the rotor (no need to remove the tire for this measurement). I'm sure you're in tolerance and you can tell that to the next buyer with the numbers to prove it.
