I have 90,000 miles on my rear brakes and they also look brand new. I replaced the fronts once. I don't think the rear self adjusters are working. I try to do the back-up adjustment thing as often as I can. I took it to a Chevy dealer a couple years ago and all the did was clean up the brakes, maybe relubricate something and they said nothing was wrong. I've pretty much just lived with it since then. I should try to manually adjust them with the drums off.
