It doesn't look "as bad" though.

You might want to disassemble the brake to check the arm alignment. If I remember the 1050 caliper correctly, there are two outside nuts to adjust the arm play. And a ring of tiny bearings lies between them.



When I look at other pics of 1050 calipers on the web, they don't all use two nuts, which is always so confusing for me to adjust (like my Modolo calipers).
