Abstract
Disclosed is a friction set for a railway disk brake system for railway rolling stock including: a shoe holder including a receiving slideway; a friction shoe including a brake pad and a profiled shape configured for being slid into the receiving slideway, where the friction shoe includes a pneumatic conduit connecting a first space delimited by a first surface of the friction shoe to a second space delimited by a second opposite surface the friction shoe; a through hole arranged in the shoe holder and laid out so as to be facing the pneumatic conduit; and a pneumatic connector mounted on the shoe holder, pneumatically connected with the through hole, extending away from the friction shoe and rotationally mobile relative to the shoe holder, around an axis perpendicular to a main plane of the shoe holder.
