Hopefully the gen6 will have rotors like my Silverado (Duralife)2 winters and 9k miles and not a speck of rust on them ever. Not even the typical surface rust on the braking surface.
The new Duralife™ brake rotors enhance braking
performance
, too, thanks to a GM-exclusive process that protects against rust that, over time, can lead to steering wheel shudder. It involves super-heating the rotors to more than 1,000 degrees F (560 C) for an entire day in a special oven, where the nitrogen-rich atmosphere promotes nitrogen atoms to bond to the rotors’ surfaces, hardening and strengthening them.
