I recall that at the time the supposed advantage of centerpulls was that they "centered" better. That is, because the brake cable pulled from the middle, both pads would contact the rim more or less at once, while on a sidepull, one pad would contact the rim before the other side began to tighten in. Campy was touted as the first sidepull to stay properly centered.
In reality, I've found that the Universal Super 68 SP's stay centered as well as Campy NR, although the Campys are undoubted a whole lot prettier. The difference between CP's and the old sidepulls may also have been exaggeratted, along with the real importance of centering. After all, at least in racing, if you're hitting your brakes all that frequently, you'll end up off the back of the peleton anyway. I read somewhere many years ago that the real reason for the switch to CP's was that Jacque Anquetil was using MAFAC CP's, and the reason for the switch back to SP's was that Eddy Merckx used Campy SP's. Probably a lot of truth to that.

Joe,
I started riding in 1955 and the only brakes available were side pull Universal and Weinmann. The Swiss brakes were the better of the two brands. Then, all of a sudden, the cycling world went center pull crazy about 1960-61, and it seemed that Mafac was the only brake one could get. I hated the
new brake fad–they simply didn't work as well. Also, all the fittings
on the Mafac brakes were metric. So if one didn't have their little (wonderful) tool kit, your only option was to use a small adjustable wrench that soon turned
hex nuts round.
I faithfully read the Tour copy of "Le Miroir du Sports" (as best I could) every fall. (It didn't arrive until September at most foreign newspaper stands.) That is how is first discovered that Campagnolo made
side pull brakes in 1968 by looking at the pictures. There was also a review in the British weekly "Cycling & Mopeds." I asked a local bike shop here in NYC that imported Frejus bicycles to get me a pair of the
new brakes. The owner, Tom Avenia, was a cycling buddy and I had them by the spring of 1969, and so did every other "serious" cyclist I knew.
In those days that would be enough to count on your fingers and toes.
