2019 Brakes 65,000 miles Front are 8mm. Rears are 3 mm.

I think excessive rear rotor wear is caused by the Anti-lock, skid control, sway control built into the brake system. It seems to be more common to wear down the rears than it used to be.

That seems really fast. Possible Defect in the rotors?

I would say defect. There was no lip or noticeable wear. Brake pads were even. Fronts are fine. I don’t drive aggressively.

That looks a whole lot like a seized parking brake cable, or stuck slider pins.

I would agree except the pads look less than half worn both side the same and inner and outer the same. Calipers were not seized and slid fine.

I would add I NEVER use the parking brake.

Thing with replacing rotors is that usually aftermarket ones aren't as good, and I'm including replacement Motorcraft rotors here. They're usually just not as good as what comes off the assembly line.

Dang I didn’t know that the motorcraft weren’t the same as the off the line, that’s why I wanted to go the motorctaft.
Now I wonder what the assembly line issues these trucks for the rotors…

ensuring oem or better quality with the brake components is important (too me.)

the dealer I go to uses motorcraft for their replacement so that was my reason for even mentioning. (Heavy sigh)

Well, thankfully most of the time, brake rotors don't just up and fail unless they are severely abused/rusted. I'm pretty agnostic as far as brand and will usually go with the least expensive that is backed by a company I've used before.

I'm generally harder on rotors than 90% of the people out there and have never had a failure, and I've had front rotors on my Accord look worse than the ones above (Heavy, V6 car, undersized braking system, and a lead foot behind the wheel) and still never had a failure.

I put a lot more thought into keeping fresh fluid in the system and monitoring the slider pins to make sure they don't seize up. Thankfully, I'm in a climate that is kind to brake parts for the most part. People in the salt belt have it way worse. They sometimes have to replace ALL the parts with every brake job.

That’s rather comforting. I do live near the ocean most of the time as I mentioned earlier, so I’ll be diving more into the components involved since salty water is really mean to things.
Thanks again.

Wonder what the OP is gonna end up doing.? Now that his original ask of what’s the best procedure? I’m kinda nosey?

Sort of off subject but seeing the heat damaged rotor reminded me of this similar find when I pulled the LF wheel off of a car- Customer stated noise (JUST STARTED) when braking. (Hmmm I wonder why?)
The OB pad material was GONE and all that was left was a thin metal backing with the tabs holding on the caliper.
This one stayed with me and had topped the worst I have seen, and owner let it go that long before addressing it.

And I thought, no way the noise (Just Started)

Similar Pic, Borrowed from the Web.
If cell phones were around at the time, it would have been pic worthy.

I'm at 126K and still have 8mm all around...I will be replacing all the pads with OEM and keep the rotors as they are all flat and smooth...

You apparently drive a lot like I do!

Nothing better than rolling past all the Jackwabbits at the stop light just as it turns green...?

I think that these pics of heavily worn rotors have a lead foot issue, maybe.

Oh well at least it had good cooling.

lol just started??? ?… Helen Keller would’ve seen that there was something wrong way before it got this far… the individual who said it just started needs to “Stop the Cap.” As the kids say. ?

My rear rotors and pads were toast at 34K. Front were fine. No idea why so soon and why the fronts were OK. Cost me an arm and a leg at the dealership. Posted on this, noting the price of ford parts vs ford parts from ford.
