The Gold Series hard drives are made in a single piece of stainless steel, according to le design and construction line that respects very tight tolerances imposed and with processing cycles that guarantee le maximum characteristics of flatness and concentricity. The great experience gained da Brembo has made it possible to define le geometries, le tolerances and picorrect sizes for each type of motorcycle and use. In fact, thanks to a specific study of processing tolerances, the special conformation of the Brembo discs allows to transmit the braking torque in an effective più, also offering a better resistance to thermal and mechanical stress. Gold Series is the product with which Brembo entered the racing world in the mid-1970s, quickly becoming the industry's benchmark for records.
