Brembo 15mm RCS Radial Front Master Cylinder


Product Description

The Brembo 15mm RCS Master Cylinder is the perfect size for 690 SMC-R, 701 Supermoto, 950/990 Adventure and 125-500 Supermoto racers running aftermarket calipers with larger pistons. It's 1mm larger piston compliments after market Brembo calipers used in those applications really well. The RCS 15 will guarantee better modulation, feel and performance.

A Brembo RCS Radial master cylinder affords top level response times and perfectly modulated braking in any conditions, with excellent linearity between the force applied to the lever and braking response. 

This master cylinder is equipped with the RCS system, patented by Brembo for adjustment of the lever's inter-axis, which allows the ideal feeling between rider and bike to be achieved. In just a few seconds, using a simple screwdriver, the brakes can be made more aggressive and responsive (20 mm) or softer and more adaptable (18 mm). With the cam in position 18, highlighted in red, a more adaptable braking feeling can be achieved; with the cam in position 20, highlighted in black, the braking feeling is sharper and more responsive.

This model uses a 15 mm diameter piston and a folding long lever, a detail which is particularly popular with Racing riders and track day enthusiasts.

Brembo uses only cutting-edge procedures and processes to ensure outstanding operation and performance. In fact, the aluminum alloy master cylinder body is obtained through forging and is subsequently machined with numeric controlled machines.

As with all RCS master cylinders, the RCS 14 also comes with a micro-switch kit to activate the brake light and a special coupling for connection to the hydraulic line.
