Seth,

Check that the wheel is fully in the drop outs of the fork.

Hi Mike -- yup -- the wheel is fully seated.  Last night, I got out my dial calipers and measured the spacers on the brake pad post.  The offending dished spacer measured 3.5 mm.  I looked at some similar spacers from other brake sets and found one at 3 and 2.5 (not sure I remember that correctly, could have been 2.7mm).  I installed the thinnest one and it did bring the brake pad down considerably.   The set up is usable as it is now and there is plenty of braking power...but the one pad is still right on the rim of the brake (definitely not 1 mm from the lip as spec'd).  I may take it to my LBS to see if I have missed some obvious step.

Hmm...I just had a thought.  I had to remove the paint on the stud connected to the fork in order for the arm to fit without binding.  I can't imagine that is causing this problem...but I mention it in the interest of full disclosure.

I too had to remove paint from the brake mount post on the fork in order to eliminate binding and allow my Avid Shorty Ultimates to work correctly. Also, I was using Zipp 303 carbon rims last year and bought the Shorty Ultimate carbon brake kit, which has significantly shorter brake posts and gives enough room to use with wide rims.
