Yeh, caliper is compressed. I think it's a geometry issue or the pads
are slightly too large. I found someone with the same issue and he

We had exactly the same problem with the AAJ set up. Like you more so
on one side than on the other...

The caliper is not supposed to touch the bracket but is free floating
on the bolts. Only the bushings in the caliper ears get tightened snug
against the bracket, the caliper itself is supposed to be able to
slide back and forth on these bushings so it can center itself on the
disc and have equal pad pressure on both sides of the disc.

The problem is the alignment of the caliper in relation to the disc.
It's pressing against one side of the disc. (you can turn this story
around too...)

If the adaptor sleeve on the shaft sits properly all the way on the
shaft flush against the stop then you need to change the 4 small
bushings that space out the bracket, remove material from these or use
thicker bushings so the bracket/caliper moves inwards/outwards so
there's no contact between the pads and the disc...
Alternatively you can also change the adaptor sleeve to suit, moving
the disc inward or outward in relation to where the caliper sits...

Remember that the caliper only moves in one sideways direction when
the brakes are applied and it needs to be able to slide enough on the
bushings/bolts to make up for pad wear and so remain self adjusting...
