Ive had wheels off shortly after i had it to take wheel skins off and i didnt notice anything with the brakes themselves. Stops just fine. Its a z71 i almost wonder if it hasn't have something to do with the downhill assist. The other day pulling into work the road has a slight grade to it and a caught a glance of the "downhill assist has been activated" (thats what i think i saw but cant say for sure as i was watching for traffic) idk but its rather unsettling as i pulled out in traffic and it did it with a expensive car behind me.
