Abstract
A combined disk and drum brake has two friction rings and an inside shoe brake, where the inside friction ring exhibits an annular channel. This annular channel serves to collect and drain water or water droplets entering into the brake disk, so that this liquid is drained over a gap between the outer friction ring and a shielding plate. Furthermore, the air guide channel is designed as a separate, water-draining channel in the brake disk.
