2020 limited. After only 13k miles rear brake pads went from 6mm to 3mm. Front went from 7mm to 6mm. Why so much rear wear. Are the rear only brakes being used with active cruse control?

If I remember correctly, it has something to do with the AdvanceTrac system. I had the same thing on my 2019 Expy.

My Gen 3 Expys (have 2) are the first of the dozens of vehicles I have owned where the rear pads ALWAYS wear out before the front. What S20 said above does make sense though, if that is the case, where the rears are being applied by the vehicle AdvanceTrac / ABS system without drivers knowledge, then Ford should have increased the size of the rear pads and rotors to compensate for the increased usage.

This is pretty common across a lot of vehicles. My 2007 jeep wrangler is the same way. However, when you put new better pads on the rear they will last longer. I think the factory pads are low noise/low dust/organic pads and they wear really fast. Putting a good quality semi-mettalic or ceramic pad will net much better longevity.

That happened on my 2015, the rears were replaced at 45k miles, the fronts are still good now at 67k. The truck was previously owned by a Federal agency, God only knows how they drove it...

It’s the material. I turned off the adaptive cruise the first day I had it off the transporter. The rears are worn about twice as much at 30k than the fronts. Dealer said they didn’t wear as much this last year so I skated by. I’ll probably end up changing them myself next year.

The vehicle steers itself for lane assist using the rear brakes. If I could bet, I would, that the lane assist feature is on high, and that if you lower the setting, it will eat less pad. It's probably a combo of the lane assist and adaptive cruise if theyre eating fast.

I have a base model XLT, no ADAS systems whatsoever. My rear pads were completely worn down when I replaced them vs. the fronts at about ~80% life. So I don't think anything like AAC or Lane Keeping has any bearing on this symptom.

I have heard that the brake system in these trucks are more heavily biased to the rears to reduce dive and are supposedly smoother when braking.

No idea if this is true but what I do know is once I replaced the pads on mine with new pads the excessive wear in the rear went away.

I have never read a comment in this forum that is inconsistent with everyone's experience on this thread. The cause is most likely "all of the above". The bottom line is that the rear brakes are undersized for the job when compared to the front, which seem to be adequate. Hopefully someone at Ford is listening......Repeat after me, "Upgrade the rear brakes, upgrade the rear brakes, upgrade the rear brakes!"

Just saying.
