The Brembo RCS19 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 19x18 bore & ratio for a softer lever feel, which may be more suited to cold or wet conditions, and 19x20 bore & ratio, to give a firmer lever, for when things start heating up!
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!
