So, they'll be good for up to 50K miles now? :rolleyes:

The OEM rotors on the GMT900's are absolute crap! Mine made it to about 40K miles, but they should have been changed at 25K miles, that's when they warped and started shaking the truck. The right front was grooved at under 10K miles.
I'm wondering what type of rotors they used on my 2010 Yukon XL as opposed to the trucks. My original brakes have 68K miles on them so far and they still have over their life left. Rotors are in great shape. I do a lot of daily commuting and pull a 26' boat w/ tandem axle trailer just about every weekend from May to October.
