Brembo’s latest radial piston pump has a small adjusting wheel that varies how much brake lever free travel the stoppers take. Real innovation or superfluous frills?

When making the trip, the first thing on the program is a detour on the country road to take advantage of the new, street-legal pump Brembo 19 RCS Corsa Corta is to show on public terrain. Ironically, Corsa Corta literally means “short race”, but according to Brembo it is intended to underline the racing character of the pump with a shortened idle stroke on the brake lever. A small wheel (photo) changes this idle stroke via a patent-pending mechanism and offers the three levels N (normal), S (sport) and R (race). At “N” the brake only engages after a long idle travel, which, according to the manufacturer, is used for safe deceleration on poor road surfaces or in city traffic. “S” supports sporty driving, and on “R” the stoppers should bite after a minimal amount of idle travel.

For the country road test, Brembo equipped two standard BMWs with the new 19 RCS Corsa Corta pump, the naked S 1000 R and the superbike S 1000 RR. On the naked bike in particular, we couldn’t find any significant differences between the individual levels, on the contrary. It seemed as if the stoppers on N were biting down earlier than on R. “When adjusting the idle stroke, it is important to also adjust the width adjustment on the brake lever,” explained Pellegrini. “If you choose a level with a shorter free travel, the lever should also be moved a little further forward.” The Brembo man saw another cause in the brake circuit: “Even the smallest air bubble can affect the braking feeling. Correct bleeding is crucial. “

Brembo 19 RCS Corsa Corta for around 400 euros

The BMWs were definitely perfectly ventilated for the racetrack: crisp pressure point, great braking feel. But here too, the individual positions of the Brembo 19 RCS Corsa Corta differed only marginally from each other. “We have to work with a certain amount of play to take into account the changing state of metal, rubber and brake fluid when it is hot,” explained Andrea Deponti, one of the two developers of the system. “In addition, there are of course always minimal tolerances in manufacturing processes.”

The bottom line is that those who already own the previous pump and are satisfied with it do not necessarily need the new Brembo 19 RCS Corsa Corta. However, if you are looking for another part anyway, you can strike. Brembo leaves the price calculation to the respective importers, but the price should be around 400 euros. Of course, the Corsa Corta also offers two options for adjusting the force-travel ratio: either more brake lever travel with less effort, or vice versa. Currently there is only the 19 pump for brake calipers with large piston diameters. A 17 version for calipers with smaller pistons (example: Brembo M50) is in preparation.
