New for 2008: The Revolutionary 19RCS Radial Brake Master Cylinder

Updated: Oct 25th, 2007

(c) OPP, 2007

Below is a copy of the official Brembo press release for the brand new 19RCS Radial Brake Master Cylinder and 16RCS Clutch Master Cylinder. It's a lengthy read so I'll summarize the main points. It's a really exciting product and it will be amazing for everyone ranging from racers, hardcore street riders, showbike creators to the average street rider. I would recommend this master cylinder and a set of HEL braided brake lines as the first upgrade to your brake system.

Update: The demand for the new master cylinders is high so please call us for more information or to backorder this part. We can be reached at 604-942-6744 or by emailing us at [email protected].


  • The revolutionary aspect is the ability to choose between the 19x18 and 19x20 configuration. If you have read our An Overview of a Brembo Master Cylinder article, you will know what these numbers mean and that there is a trade-off between the two pivot configurations. Not to say that either configuration is bad, but the rider had to choose between varying degrees of feel and power. Now the rider can instantly change the configuration to suit their needs. No more compromises!
  • Another unique aspect to this is the inclusion of a microswitch for the brake. In the past, one needed to install a banjo bolt with a pressure switch to activate the brake lights. Now, you will have the ability to hook up the stock brake electronics instead of using the aftermarket pressure switch. Cool, eh? The only other product that we carry with this ability is the new Gilles Tooling VCR rearsets - again, that rearset is the first of it's kind to incorporate the microswitch technology.
  • For racers, the adjuster knob has been relocated to the same position as the 19x18 Billet Folding Brake Master Cylinder that is used by Valentino Rossi and Nicky Hayden in MotoGP and WorldSuperBike. Two springs have been installed to ensure constant contact between the lever and the pushrod to ensure a longer lifespan.
  • The 19RCS brake master cylinder retains features that made Brembo the top brake system manufacturer today including forged CNC-machined construction and a folding lever that reduces crash damage.
Please read the official press release and click on the pictures for larger pictures of the master cylinder. If you have any questions, feel free to email us at [email protected] or call us at 604-942-6744.

NEW BREMBO 19 RCS RADIAL BRAKE MASTER CYLINDER (OFFICIAL BREMBO PRESS RELEASE)

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 such as the Brembo High Performance (HP) 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.



TECHNICAL DATA SHEET

The new Brembo 19 RCS radial brake master cylinder retains the familiar geometry, dimensions and functionality of the MotoGP component, while introducing many engineering improvements.



Adjustable Pivot Distance: RCS system

With this new patented device, the rider can set the brake lever pivot point at one of two distances, 18 or 20 mm, simply by turning a roller cam located on the front of the lever clevis. With the RCS Ratio Click System the change from one setting to another is simplicity itself, and the lever ratio can be adapted to the different characteristics of the braking system, the ride or the conditions: for example, dry or wet, road surfaces offering greater or lesser degrees of grip, riding style, and so on...



The red colour of the cam indicates pivot distance 18mm (FIG. C1), whereas the black colour indicates the 20mm position (FIG. C2). This is a feature that was until now unavailable, but now provides the adjustment that will give the optimum feel between rider, riding style, machine and circuit.

Clutch Master Cylinder

The 16RCS clutch master cylinder makes up a set with the 19RCS. The 16RCS is equipped similarly with the Ratio Click System, allowing adjustment of the feel on clutch control. Like the 19RCS brake master cylinder, this component has a forged aluminium alloy body with hard-anodized surface finish.

Hi there KeS,

It is as you say " a hole with a piston in it" but there is much more involved in it than just that.
Calculating the proper piston diameter to the appropriate stroke of rod is a very important aspect of a master cylinder. The R&D that goes into the development of a brake/clutch master cylinder is HUGE. But be assure when you buy Brembo you get the best.
Brakes are one of the first things we recommend any rider improve upon when beginning to modify there motorcycle.

Regards,
Tim

Oh, I'm not picking on Brembo, I know it makes (or can make) a big difference. It's just kind of amazing that with a whole industry out there making similar kinds of hydraulic controls of all kinds, that sell for pennies, that the performance brake industry gets such major value add. Didn't mean to rain on your promotion, just a side comment.

It's a lovely MC, and if I didn't hate my damned 748 so much I'd treat it to one!

:cheers

You didn't rain on anything :p
We do these articles to inform everyone of the advantages of using such products and how these products work.
There are a lot of misconceptions regarding braking systems on motorcycles and how they work.
We here at OPP Racing want to educate our customers as best we can so that they can make an educated decision as to which parts will suite there needs best. It may not be a Brembo master cylinder that works best for everyone and an article like this may be the information our customer needed to make that decision.

Regards,
Tim
