1. A method of making a brake shoe and lining assembly comprising the steps of:

  • (a) providing a formed lining segment having opposite edges;

    (b) providing a pair of brake shoe sections, each having a rim portion and a web portion, serrations transversely formed on the rim portion surface which is to be supportive of the lining segment, and reversely bent tab means on the outer edge of the rim portion;

    (c) mounting the pair of brake shoe sections in laterally spaced and aligned relation;

    (d) placing the lining segment on the laterally spaced supportive rim portion surfaces so that the lining segment is engaged with the rim portion transverse serrations only adjacent the lining segment edges;

    (e) forcing the lining segment into the rim portion surfaces to initiate formation of transversely extending complementary mating serrations in the surface of the lining segment engaging the rim portion, and holding the lining segment in place;

    (f) moving the shoe sections laterally together, causing the rim portion serrations to form the transversely extending complementary mating serrations through the lining segment surface engaging the rim portions and further causing the lining segment edges to be engaged by the tab means on the outer edges of the rim portions in holding and retaining relation; and

    (g) securing the shoe sections together in the web portions to form the brake shoe and hold the lining segment in position thereon by the tab means and the mating serrations.
