I put current Campy Centaur and Tektro R341 calipers/levers on my daughter's Cannondale from the late 80s. Much better than the old dia-compes that were on it. I also put Tektro RL720 cross levers on the tops because she wanted them. The whole setup works great. It does not look period correct but for brakes I'd rather have good working ones. It isn't as if the old stuff was anything classic anyway.
