Brakes-why did they wear out like this

[Tamago]

did you check to see that the pins were not bent? they could slide smoothly with no braking pressure on them, and bind under load.

Wouldn't pin problems most likely cause outboard wear, or crooked pad wear? And inboard pad problems are from a sticking piston, either from square-cut o-ring not rolling back or corrosion buildup inside the caliper?

I'm guessing buildup between inboard pad and rotor and nothing wrong with hardware.
