The Brembo RCS (ratio click system) master cylinder is used throughout the racing world, an upgrade to the basic race forged master cylinder, allowing the user super quick adjustment of the lever ratio to give a firmer, or softer lever, depending on track conditions
the unit is created by drop forging a piece of aluminium billet into the basic final shape, before CNC machining the internal dimensions then finally black oxide finished ready for assembly. the lever has a simple screw mechanism to select between 18 ratio for a softer lever feel with a longer pull or a 20 lever ratio, to give a firmer lever with a shorter pull.
Brembo forged master cylinders are made for racing - they are assembled with precision to ensure there is no dead lever travel in the system
Note:
Aftermarket master cylinders use a different thread pitch banjo bolt, to OEM master cylinders, remember to add one to your order from the accessories category if needed!
