Abstract
A multi-disk braking device for a vehicle, particularly a train equipped with a braking retarder, includes a first set of metallic braking disks and a second set of carbon braking disks. Under normal operation of the train, the braking retarder is used to slow the train to a predetermined relatively slow speed, and the metallic disks are then actuated to complete the stop. If the braking retarder fails, the carbon disks, not used in normal operation, are actuated to bring the train to a slow speed or to a complete stop.
