2016 mileage on Front Brake Pads before replacement

Drum breaks go out also from use.
Have had many replaced over the years on my peterbilt's and trailers.

 

he was kidding. And Drums don’t take breaks, they brake

 

Disassembled and cleaned my front brakes today.

2018 double cab, driving lots of highway with a bit of city commute, 40,700 on the clock.
Pads were measured using digital calipers.
Remaining life ranged between 60-70%. Very surprised at how much meat was left considering I was ready to replace them.

For some reason my outer pads are wearing a tiny bit faster than the inners. Anybody else experience this? None of the pistons are seized up.
