I live in New York on Manhattan's snow blown west side, so riding, this week, has been out of the question. I took the opportunity to build up some older Ambrosio aero rims mated up to Campy low flange Record hubs. The true and dishing went well, for an amateur, but I see now, that these older Ambrosio rims do not have straight sides like modern aero rims. Subsequently, the brake blocks only touch at the very tops of their surfaces. Is the best course of action, now to file the brake blocks to match the angled rim surfaces? If that indeed is the case, what is the best method to proceed?

When faced with this a few years ago with some Campy aero-ish rims.
I used a belt sander with a 80 grit belt to remove the brake material.
I just "eye-balled" the angle, it worked very well.
I don't know how long it would have taken to wear in the pads without
this attention on the anodized braking surfaces of the particular,
probably off topic, rim.
I went with Koolstop ATB pads with a ball washer mount, allowing easy
alignment when I transfered this wheelset to my downtown beater fixed
gear last year.
