I only use the AutoZone Duralast Gold pads now- I had bad results with most others whether it was dusting heavily, fading badly, or squeaking constantly- I used to be a NAPA guy, but their best metallic pads let me down a couple times with fading badly on heavy braking. My avalanche and my 2003 sierra both had Duralst Gold all the way round, and it made a big difference- I also run them in my wifes Kia Sorento, and that thing will blow your eyes out of their sockets when you stab the brakes hard!
