Hi Gang!
I finally got in to see the dealer last week. I was starting to get a bit of a laundry list of items I wanted checked, the least of which were the rear brakes. In any case, they are telling me that the wear I am seeing is quite normal. They had a Silverado with just under 20,000 km (12,470 mi) up on the hoist next to mine & it had about the same amount of wear that mine did & I am at 36,000 km (22,370 mi). They even pointed out that the liners are simply not that thick anymore, referring to the replacement set I had purchased (aftermarket) in case they were not going to replace my rears on warranty. The new liners aren't that thick at all (I didn't actually measure those). SO! I asked them if this is 'normal wear', why did the last dealer I went to (before I moved out of town) check them off as marginal on their inspection sheet at 17,000 km (10,560 mi)?! Their answer was that the Tech's should have known better. The inspection sheet is generic & does not reflect the spec's of the newer vehicles. If this is in fact the case, I suggested they re-vamp their checklist sheet to update it to match the vehicle they are inspecting! In any case, the fact that I've got two dealers providing me with different information does not instill a lot of faith, especially when I hear a story about someone's cyllinder pin popping out because the shoes were waay worn-out! All I can say is that I'll be keeping my after market shoes & watching the wear very closely. I'll replace the dang things myself if I get uncomfortable with what I'm seeing. I never trust my destiny to someone else if I can avoid it!
