The best brakes I own , and I have a lot of the brakes mentioned above, are the Gran Compe NGC 400 with Aero levers that came on my Medici. Coming to a complete , controlled stop , even on a down hill , is easy. When I bought the bike , the owner had a box with the original Campy SR brakes but I never put them on the bike after the first time I rode it. The bike is a 1982 so I’m guessing they are mid eighties brakes. The calipers are exact copies of Campagnolo but seem to work better, not quite sure why. I think second in line for stopping(not looks) is the Mafac Racers on my Mondia. The Mafac can be adjusted perfectly but take a bit longer to set up. Once adjusted properly , they stop very well. I also agree about Universal brakes , they work well too. There are quite a few brake choices for a vintage bike and some are better than others, but set up and brake pad choice are crucial for success , regardless of which brand.
