The evolution of Brembo calipers
Since the very start of the Superbike World Championship in 1988, Brembo calipers have been the first choice of the main teams. At the beginning, they were in two pieces joined together with four screws. To overcome the rigidity limits and differing technical expansion rates of the aluminum of the calipers and screws, in the second half of the 1990s Brembo introduced monobloc axial brake calipers.
A few years later, Brembo replaced its axial calipers with radial ones - more difficult to produce, but undoubtedly more incisive: there's less mechanical stress on radial calipers, which means less elastic deformation and therefore enhanced braking sensitivity. The current radial calipers are made of nickel-plated machined aluminum.
