Tuning up a Trek FX2.
Rear brake caliper is sitting too far forward causing uneven wear on pads + spongy brakes.
See pic 3 for exploded view of adapter(s). I've tried flipping these round in all manner of ways to no avail.
I get the impression this has been a bodge job by someone as the countersink bolts don't look stock/don't fit well.
Anyone have any ideas which adapter I need? I have tried to look but there seems to be no straightforward guide.
Any help would be much appreciated 🙂

My phone bugged out when this uploaded so apologies if it appeared twice.
I think your frame is designed for flat mount calipers, and you appear to be using post mount calipers.
Who ever sold you that bike bodged it. You need a post to flat mount adapter.
