(Images are front rotor, front pads, rear pads)
This is after bedding in brand new SwissStop pads and rotors and a single 40km ride. I also added an adapter to the front to go from 160-180mm, in case that's relevant.
I've just changed the pads (after a previous thread pointed out that the ones I had weren't suitable) and noticed this. It's much more prevalent on the front.
When changing the pads, I did clean and re-oil around the pistons (mineral oil + cotton bud). The front ones that were only pushing from one side (maybe why they're worse?) are now pushing evenly and I think the backs were better as well. Will this be enough to fix this issue?
Any other likely problems for me to look at?

Can you see where the pads are in relation to the brake track on the rotor when they are in the caliper? The bottom portion of the pad being worn away almost makes it look like only that part of the pad is on the rotor but it does also look like the top part of the pad shows normal use too. Did the larger caliper adapter get installed without a larger rotor or perhaps the incorrect adapter for a 180mm rotor?
Edit to also add: the inner ‘rough’ section of the brake track on the rotor is indicative of metal-on-metal wear as well as the discoloration on the rotor arms almost being blue happens at very high temps. This would further support that only a small portion of the pads are contacting the rotor but that section or the brake track corresponds to the bottom of the pads and would seem like they are are the correct distance from the hub. Could you share some pics of the pads installed in the caliper?
