You're right, I changed the pads last night with no Scan Tool and had no issue, other than my brake percentage still reads "Service System". It's the same as my 2020. A couple people at the dealer had me scared that there was something different from 2020-24, and that if I didn't put the truck in "Brake Service Mode" that I would damage the system. I guess it's worth mentioning that a person should pump the brake pedal a few times once everything is back together before turning the truck on. I was told that pumping the brakes back up, with the truck on or running afterward could throw a code? Pretty sad that this is the new norm for brake wear! or at least that's what they want us to accept? Also pads looked basically the same on passenger and drivers side, this was my rear axel fronts were still at 65% Thanks for the info Mike!

I’m posting this because the explanation I received from my dealership was honestly pathetic. The truck in question is a 2024 GMC Sierra 3500HD Duramax. It currently has 49,000 km (~30,000 miles) and is still under the 3-year bumper-to-bumper warranty. When I inspected the rear brakes, I found severe uneven pad wear: Inner pad (piston side): ~2 mm Outer pad: ~8 mm That does not look like normal wear. For context, my previous truck (2020 3500) was used under significantly more severe conditions and went well over 100,000 km (~62,000+ miles) before brake replacement, with roughly 25–35% pad life still remaining. That truck did not exhibit uneven pad wear. When I raised this with the dealership, I wasn’t told it was “normal” or that something had failed. Instead, I was told this wear pattern is “very common on all the new trucks,” with traction control and Auto 4WD cited as possible contributors — and that this is simply something owners should expect going forward. That response is unacceptable. If traction control logic, Auto 4WD behavior, EPB design, calliper hardware, or software is causing rear brakes to drag or wear unevenly at 49,000 km / ~30k miles, that’s not an owner issue — that’s a design or quality problem. Especially when the previous generation performed far better under harsher conditions. What adds to the frustration is reduced serviceability at the same time: Rear brakes are tied to an EPB system that requires a high-end scan tool just to retract the callipers. Manual EPB release methods that worked on earlier models do NOT work on this year. So owners are dealing with shorter brake life, uneven wear, and higher barriers to basic maintenance. I’m looking for input — particularly from GM techs or engineers: Have you seen this inner-pad-only rear wear pattern on 2024 HD trucks? Is this truly considered acceptable, or is it a known design or software issue? Has any root cause been identified (EPB logic, calliper design, slide hardware, software updates)? What scan tools are confirmed to work for EPB service mode on this generation? A 49,000 km / ~30k mile HD truck under bumper-to-bumper warranty should not be consuming rear brakes unevenly — and owners shouldn’t be told to simply get used to it. Appreciate any insight.
