  • Publication number: 20030057038
    Abstract: Drum brake linings having an integral surface texture on the friction side surface of a drum brake shoe are described. The surface texture may be achieved by spraying metal droplets onto the surface, fusing a metal pattern onto the surface, or creating a series of protrusions by scraping or cutting the surface. The surface textures have excellent shear strength and retention profiles.
