This may be grasping at straws, but have you checked to make sure each caliper has correct inner and outer pads?

The inner pads should have the wear tab indicator on them. And the tab should be closest to the abutment bracket (holds the e-brake cable).

Also measure the pads when installed for parallel. Measure one side then the other. The difference should be no more than 0.15mm. Then measure top to bottom. This seems like where your problem may be.

The picture of your wear says it's probably something other than mis-installed inner and outer pads - but at least you'll eliminate this possibility. Just trying to help.
