Er bestaat nu toch ook een Brembo pomp met variabele as/zuiger hartafstand?
De 19RCS als ik me niet vergis..
edit: NEW BREMBO 19 RCS RADIAL BRAKE MASTER CYLINDER
The Brembo radial master cylinder has effectively revolutionized motorcycle braking systems over the past ten years. Designed originally for use on Racing machines, it has become more and more popular over time for Super Sport, and even Naked bikes, while retaining the identity of an out-and-out racing component, still used today in MotoGP competition.
Today, bike enthusiasts everywhere can upgrade the braking system on their machines at a stroke, simply by replacing the production master cylinder with a Brembo radial, confident of the top-flight performance associated with many years experience acquired by the company in designing and engineering braking systems.
Why “radial”? The definition indicates a configuration whereby force can be transmitted to the piston “in phase” with the force applied by hand to the lever, eliminating the friction that would be generated if these forces were separated. In other words, the effort exerted by hand on the lever and the force applied by the lever to the piston are both generated in the same direction — radially — relative to the point where the cylinder is anchored, i.e. the handlebar.
With this type of construction, the master cylinder can be designed with the focus on optimizing hydraulic and mechanical ratios, and consequently on improving its performance. This means that the force applied to the lever can be converted entirely into powerful, dependable and precise braking action.
For twin-disc systems; there are currently two models of Brembo radial master cylinder available: 19x18 and 19x20. The choice between the two models will be based essentially on the feel that the rider is able to get from the two solutions.
The 19x18 cylinder has better modulation, given its marginally longer operating travel when compared to the 19x20, which on the other hand offers a slightly quicker response.
As a general rule, the 19x18 is recommended for bikes with 4-piston calipers (diameters 32/36, 34/34 and 30/34), whereas the 19x20 is more suitable for other calipers.
Brembo experience favours 19x18 for track, and 19x20 for street.
Today, after 10 years as a brand leader, this legendary product has been updated with a number of significant new engineering features, all derived from MotoGP, and is now marketed as the new Racing radial brake master cylinder.
