DRUM BRAKE LININGS HAVING THERMALLY OR MECHANICALLY APPLIED METALLIC SHOE ATTACHMENT ENHANCEMENTS

摘要

Drum brake linings having an integral surface texture on the friction side surface (18) of a drum brake shoe (20) are described. The surface texture may be achieved by spraying metal droplets (10) onto the surface (18), fusing a metal pattern (40) onto the surface (42), or creating a series of protrusions (66) by scraping or cutting the surface (60). The surface textures have excellent shear strength and retention profiles.
