Mafac introduced the CP brake in 1952 - the others followed in the late 50s

the article doesn't date it, but braze on mounts were offered early
For the rear brake they made an alternative fitting in which the centre bolts fits vertically to the frame. This method was used by many French builders as it gave a neater way of fitting the rear mudguard (without the need for a bridge).
Also a heck of a lot easier to keep braze-ons clean
