Abstract
A brake disk comprising a pair of spaced friction disks against which a brake lining on a brake shoe can be applied to produce a braking effect are interconnected by a plurality of ribs and guide vanes so as to define ventilation passages between the friction disks. Strips of vibration damping material are positioned in radial grooves formed in the mutually facing surfaces of the friction disks. The inserts comprise a metal which damps vibrations and has a coefficient of expansion greater than that of the iron material from which the friction disks are formed and may comprise such metals as lead, bronze or copper.
