The Brembo 19 RCS CorsaCorta radial brake pump is a 2017 novelty, born directly from the experience of the Brembo Racing racing department. Ten years after the appearance of the RCS, Brembo introduces the RCS Corsa Corta brake pump, which allows you to map the very first part of the lever excursion through the adjustment of the idle stroke.
The RCS Corsa Corta has the possibility of calibrating this parameter on three positions (RSN), to get the maximum feeling of the braking connection according to this scheme:
Position R "Race" the idle stroke is minimized, the lever will be more reactive.
Position S  "Sport" the idle stroke is in an intermediate position, as is the feeling at the lever.
Position N  "Normal" the empty stroke is greater, therefore there will be a wider modulation and a smoother braking attack.
