Are you all seeing rear pad wear like this???

Pad wear on the rear. Both sides look just alike.

Pad wear on the rear. Both sides look just alike.

Thts bizarre, my fronts were f’ed up at 17,000 miles and when they removed them from the caliper, one split in half and the other had full width fractures in the pad. Then they found out I had two bad 4x4 actuator assemblies. Fixed everything and they tried to get me paying for pads and resurfacing rotors. Long story short, they determined faulty pads led to warped front rotors so I got all new stuff for free. I never had rear brake issues though..

Sliding properly? No rust under any mounting hardware?

Warping rotors seems to be a thing on these trucks... Ours are definitely warped, and it is on my list for next time it goes in for an oil change. They will be doing it on their dime.

Both sides of ONE rotor (outside & inside pad) or Both rotors (outside pads)?

If one end of pad backing wasn't sliding due to metal tang interference or other reason?
Should be able to tell when disassembling. I always take a file to the new pads to clean up any extra fabrication remnants.

On the warped rotors ... there is a school of thought that rotors don't warp.
I guess you're not in that school. I've never had a warped rotor so I dunno.
BUT I do believe they can be warped by rapid temperature drops. FWIW

Ok, maybe warped isn’t the correct terminology. There were several relatively deep scours in the rotor faces from dirt and debris stuck between them and the pads.

Did not get a chance to pull the wheels. Weather was finally decent so I was unwinterizing my chainsaw, string trimmer, and DR Field and Brush mower.
Got the wild hair to check the brakes on the truck as I bought it about a year ago. No issues just figured I would take a peak.
I can only see the outside pad on each side and the wear is pretty much identical.

No need to argue symantics one mans warped rotor is rotor runout to others but we’re all talking the same thing.

Guess, I’ll pick up some pads for the rear and rotors since I don’t know if these have been turned or not.

Trying to decide if upgraded brakes for the rear are warranted. Or if a the NAPA Premiums will be just fine.
Still trying to decide between Baer and EBC for the fronts when they need swapped out.

at 9700 miles all pads measured 8 mm at oil change
15000 miles all were at 7mm
22000 measured 8 mm yep ..
29000 all got the GREEN check mark with no measurement indicated
so i am thinking the 7 mm was a fluke

i dont hold my brakes or ride them, i coast alot if in traffic
but once i stop, i hold the pedal for 20 or so seconds then roll enough to put the hot caliper on another section of the rotor to prevent warping
current mileage is 30,800

Rear rotors or drums rarely get warped/ out of specs. The reason is the fronts handle 70 percent of the stopping force. The rears are more like an equalizer. With only 30 percent of the stopping duties, their like rear deck speakers in a car, more a fill, than a total sound. Don't get me wrong, you need that 30 percent, but the heat build up is much less on your rears. The only exception, is if your Ebrakes are dragging, but even then, it's the small shoes in the hat part of rotor that suffers. Can't see from your pics on my phone, but uneven wear can be either from a non sliding caliper, a warped rotor, more than the customary .004 out of specs, or from a botched install. I've seen customer's trying to install their own pads, and put the backing plate towards rotor. Unbelievable grinding.

I would clean/lube the slides and pins.
