The master cylinder, used for all classes, is made of aluminium, machined from solid and produced using CNC machinery. Inside the cylinder there is a 19 mm diameter piston. Located above the cylinder is a “stroke recovery” bowl, whose task is to guarantee the same stroke of the brake pedal even when brake pads are worn. Externally, the master cylinder is titanium-gold anodised, like the other accessories on the chassis; the oil in the system is Xeramic brake fluid dot 5.1.
