The Brembo second generation of the dual-cast brake disc is an alternative to the classic version already available on the market, improving the fluid dynamic efficiency and therefore reducing the operating temperatures, thanks to an optimization of the drag and ventilation geometries. The Brembo dual-cast disc has many benefits: weight reduction by about 20% (compared to an integral disc of the same dimensions), greater comfort, reduction of corrosion and wear and better performance of the components. A fundamental characteristic of this type of disc is the cast iron braking band and the aluminum bell, which combine the advantages of the way cast iron performs at high temperatures with the lightweight properties of the aluminum. The innovation consists in the way the two materials were combined into a single component and in the performance of the disc itself
in fact, it is an integral disc at low temperatures and it performs as a floating disc at high temperatures, when top performance is demanded and the disc tends to deform.
