Rear brake/rotor replacement mileage?

[Blue22]

I have replaced rotors and pads on several vehicles of mine and haven't seen grooves like that on either the pad or the rotor. Something must have gotten wedged in between the inboard pad to cause this in my opinion.

They do stone chipping on the roads around here in the summer time. Could have gotten some stones in there.

they do that here, as well as where I grew up.
not saying it can’t happen, but I’ve never seen the chip gravel do that

Definitely not normal, especially for OEM equipment. I'd be looking for a caliper issue like a stuck slide pin. I have 46k miles on my truck and just inspected the brakes on the last rotation. I have tons of life left and wouldnt be surprised if they got me north of 80k. A friend of mine has a 2016 F150 and did his front around 100k, rears around 80k. He's up near 125k and on his second set of brakes. I expect the same duration on mine.

That said, I had issues with whatever was on my 2013 F150 when I bought it. It had some cheapie drilled/slotted rotors on it. They didnt last 25k before I had to replace them.

That was my issue
Stuck pin

Mine are toast, on the right side, the bottom pin was froze, 34,000 miles, had zero grease inside the boot!
Question, do we have the 336mm rotor?

MAx tow so the larger rotors.

I’m currently at 111,115 miles on the original brakes and rotors. 38k seems way too early.

I have already gone through two sets of rear brakes up to 90,000kms so roughly 45,000kms per set.

Max tow, and yes i do tow, but i am very gentle on the brakes as i am so used to one pedal driving. Apparnetly normal wear on rear because the rear brakes constantly intervences to keep the truck straight and reduce fish tailing and improve traction is what i am being told.
