Abstract
The disclosed method involves making a brake shoe from symmetrical halves by placing a formed lining segment in position on laterally spaced brake shoe half sections with forces applied thereto to engage serrations in the shoe web half sections, forcing the shoe half sections together to form a full shoe while concurrently moving the serrations across the lining segment to form mating serrations on the lining segment and thereby provide serrated mating engagement of the serrated shoe rim with the lining segment. Lining segment retaining means formed on the shoe web half sections engage and hold the lining segment on the assembled shoe, the shoe rim half sections being secured together by fastening means which may be rivets or spot welds, by way of example.
