you should still be able to run a brake if it's on the slim side... i don't see what the problem is...
i have the exact same bike (albeit w/ gears on it) and i run 700 x 25, which isn't really applicaable your situation.
BUT, the bike was originally sold as a high-end tri bike, so i'd be really surprised if you could get a 700 x 35 0n there.
that being said, i don't think there's any reson you couldn't grind down that washer on the rear brke bridge to give yourself some extra room.
don't remove the bridge itself though.
If you move your rear wheel as far back as possible in the drops, does it increase clearance a bit?
Frankly, some tires are simply measured incorrectly. Racing oriented tires tend to be undersized so they can brag of being lighter than they really are, while a tire like an Armadillo will run quite large. Also, some tires seem to have a rounder profile or more V-shaped profile, compared to flatter tires (which are sometimes a bit wider). In any case, I wouldn't expect any 35c tire to fit an old road conversion.
Do not remove the rear brake bridge- but you might try filing down the "washer." It doesn't provide any structural support and it will give you a few more millimeters.
I actually just did this the other day to my new (to me) Dave Scott Ironman Expert. It worked well.

tighten all the spokes on the offending wheel 2 full turns. should do the trick...
I had the same problem on my track frame riding like size 25 cross tires. I switched once normal road grit started to wear away the paint. If you just leave it, in my experience, it will sand away its own clearence.
I went from 25c Gatorskins to 23c Vittorias and started rubbing on the front fork on my Bianchi. So I took a dremel to it - worked great, no more squeaking sounds. It looked like someone had aready done that before, too.
Looking at your pics, it looks like you don't have the rear wheel all the way back in the dropouts - the further back that they are, the more clearance that you'll have... Of course, less gear ratio options...
In that pic, the wheel is about in the center of the drop outs...I checked earlier today and moving it through the dropout really did not have a noticeable affect on the clearance. I think I will try increasing the spoke tension a bit and then just go with it. Ill file the bridge or go for a slightly smaller tire if it gets to be a problem.
