Abstract

A brake disk has a thickness D1 and includes two friction plates disposed parallel to each other, between which an airflow duct having a width D2 is located in a substantially central position. The brake disk is made of a gray cast iron material containing molybdenum. The ratio of the disk thickness D1 to the airflow duct width D2 is 3.0.ltoreq.D1/D2.ltoreq.5. The brake disk has a great resistance to temperature change and a long operating life.
