That picture Via Jenson, looks like they left off the angle adjustable washers (just like on V- brake pads)
so maybe the whole caliper is askew.. my BB7, as supplied have them on both sides of the post mount -to ISO
That aligns the disc and the pads.. [hold the brake on then tighten the bolt.. ]
IDK, Cant see over the web, in text, (i'm old and, and hands on.. )
try going to a Bike Shop.. getting it up on the repair stand ,
high enough to see the clearances between the pads and the disc..
the concave/convex washers accumulate from V pad replacements,
so in the LBS there should be a collection of used ones.
IF you Upgrade to hydraulic , they self adjust for pad wear, automatically [ Like on Cars]
so may take care of that continuing need for attention,
rather than the need to keep it in adjustment yourself.. .
