i used them on my NNBS sierra, the rotors were just fine, lasted a while etc. the pads were cheap ceramic pads that squeeled when wet or cold. i swapped them out for some good EBC pads and got much better braking and less dust. not that the motives had high dust. i have a brand new set of brakemotiv rotors at the house for the Yukon. look just as good as the ones i had years ago on the sierra. i ordered wagner HD ceramic pads this time around as I'm on a budget with this truck. oem type pad with slightly better grip and less dust for $24/26 cant be beat.
