Disc brake system for a vehicle

includes disc brake system for a vehicle, comprising a brake disk, a brake caliper with at least one brake lining and a suction device, wherein the brake disc rotates with a movement of the vehicle and a disc-shaped friction ring with at least one axial friction surface, the caliper embraces the friction ring sections, so that the at least one brake pad is pressed during a braking operation on the corresponding friction surface and wherein the suction device comprises at least one drive wheel and a fan arranged in a housing, and an opening formed through the housing intake port, wherein the drive wheel by rolling on the brake disc in rotation can be displaced, and transmits this rotation to the fan, whereby a suction of air is created through the suction port, separate particles are sucked into the housing of the suction device with the one of the at least one brake pad, and wherein the Antriebsra d rolls only during braking on the brake disc.
