In 16 years and 255k miles I have replaced my rotors and pads three times on my 06 dually. I was running ceramic pads and that was a problem. They didn't stop well when they were cold and ate the rotors while showing minimal wear on the ceramic pads. The current (non ceramic) pads and (drilled & slotted) rotors are doing well. I am sure a contributing factor to using three sets of brakes is the 24k GCVWR (truck & trailer) and the fact that much of the miles were in the Rockies. This is the best truck I have ever owned.
