You should be able to get a brake on there - some old ones (i.e. not dual-pivot ones) from the seventies and back should have quite tight clearances so would be OK. If you want to put on a modern dual-pivot brake like a Shimano 105 you'll have to do some 'modifications' to get it to fit (grind off a few mm from the knuckle, file out the slots that hold the brake-block carriers). Wheels look just the right size to me.
