Brembo 15RCS CORSA CORTA RR – Race Replica Radial master cylinder

The floating piston and gaskets are the same as the components used in MotoGP, as are the bleed and brake fluid delivery circuit couplings. These are inclined by over 30° to facilitate bleeding of the master cylinder.

The lever, modified in shape, retains its characteristic feature that has made it famous among enthusiasts: it allows the riders to tailor the “bite point” exactly where they want it, with an easily accessible selector on the top of the master cylinder itself. The selector operates a cam mechanism to let the user choose between three different responsiveness settings.

In the Normal setting, indicated on the master cylinder with the letter N, the bite point starts more gradually, making it suitable for city riding or braking in poor grip conditions.

The new Brembo 15RCS CORSA CORTA RR also features the RCS (Ratio Click System) system introduced 15 years ago on the Brembo 15RCS radial master cylinder. This lets the rider select a fulcrum-to-piston distance of 18 or 20 mm by simply turning the adjuster screw on the front of the guide lever by 180° with a screwdriver. The system uses a cam (red when set to 18 mm, black when set to 20 mm), which adjusts the distance between the fulcrum point and the contact point with the master cylinder push rod by 2 millimetres: this changes the distribution of the braking force without altering the performance of the system in terms of pure power.

The adjustment system allows the rider to achieve complete feeling with their bike and adapt braking performance to their riding style, the bike, the weather and road conditions, relying on three different master cylinders in one, bringing the performance of the braking system as a whole to another level. In fact, the choice of two fulcrum-to-piston measurements (18 and 20 mm) and three bite-point settings (R, S and N) offer a total of six different settings.​
