200 series with rear brakes wearing faster than front

[LC neophyte]

2018 Land Cruiser with 44,000 miles. Most miles are long trips, with some suburban driving but never in stop and go traffic.

I brought into my dealer, who until recently, had sold more Land Cruisers than any location in the States. They see a lot of Land Cruisers, and have a dedicated service rep for them.
When I had and oil and filter, and tire rotation, we discovered that I'm in the yellow zone on the rear brakes (6 mm both sides), and green (8mm in the front). My rep said that he is seeing this more and more, not just my vehicle. Rear brakes wearing before front. Huh?

Normally, I brake early and very gently. The only thing that comes to mind that may bear consideration is the use of crawl control in sand. Early in its life, I brought the 200 series to Silver Lake State Park, MI as suggested by member Sand Road. I deliberately got the vehicle stuck in deep, loose sand to see if it would chug its way out. ( it didn't, needed to be towed).
Now, I wonder if that traction modulation of pulsing the brake for 4- 5 minutes caused premature rear brake wear?

Anybody else with rear brakes wearing before front? Thoughts?

I;d say my experience on the 200 is consistent with this - rears wearing before the front.

I might be wrong on this completely, but i recall a discussion somewhere that the breaking circuits are built with this bias due to the weight of these rigs, 3rd rows full and the need to be able to do a full emergency stop.

After several rounds of warping on OEM rotors (Previous owner and dealer CPO process over-torquing) i too am a bit more gentle on my braking, doing as you do - early and with mechanical sympathy….

I consider this extremely unlikely. Compared to the heat involved in even a single stop from freeway speeds I can't see even much longer crawl control done at such low speeds contributing wear of an meaningful amount.

As crazy as your theory sounds it correlates with my brake wear experience with a different 3 row full-size SUV and many other owners on a forum for said vehicle.
