Abstract
A brake lining for a railroad car has a frictional surface on a brake disc that is pressed by a brake caliper. Friction bodies are pressed against the frictional surface of the brake disc and a back plate is mounted to the caliper to support the friction bodies. Each of the friction bodies is formed with a friction material which contacts the brake disc frictional surface, and has a base plate attached on the back plate side of the friction material. The base plate has a protrusion formed on its back side. On the friction body side of the back plate there is formed a groove which contacts the protrusion formed on the base plate. A disc spring or a spherical-seated structure is disposed between the base plate of each friction body and the back plate. Friction bodies are prevented from rotating at their attached places, without adding new components.
