Abstract: A brake shoe assembly is formed by precision stamping a net shaped web blank having a series of tabs projecting outward therefrom and stamping a corresponding table member provided with tab receiving apertures and bending the table member into a semi-cylindrical segment. The web blank and the table are assembled causing the web tabs and table apertures to be interlocked securely locating the parts temporarily prior to the cooperating tabs and apertures being permanently joined together using a hot staking process without any portion thereof extending substantially beyond the outer semi-cylindrical surface of the table.

Abstract: A brake shoe assembly is formed by precision stamping a net shaped web blank out of steel forming a series of tabs projecting outward therefrom, stamping a corresponding table member provided with tab receiving apertures, and bending the table member into a semi-cylindrical segment. The web blank and the table are assembled causing the web tabs and table apertures to be interlocked securely locating the parts temporarily together. The cooperating tabs and projections are then permanently joined together using a hot staking process which quickly heats, radially deforms and self quenches the tab to metallurgically strength the joint.

Abstract: A replaceable roller insert is provided for supporting a cam roller follower within roller supports acting against a cam element moving at least one brake shoe inward and outward relative to a brake drum where the roller insert is easily replaced by removing a worn roller insert and mounting a replacement roller insert to the brake shoe web.

Abstract: A roller follower (12) and bracket (20) combination for use in a rotary cam type brake shoe assembly (100) is provided in which bracket (20) is supported on a web (2) of a brake shoe in such a manner that, when a free-end (27) of bracket (20) is inserted into an opening (26) in a trunnion (24) of a pin (11) that supports roller follower (12) for rotation, bracket (20) is operative to prevent roller follower support pin (11) from being rotated by the cam to lessen noise heretofor created by the rotation of trunnion (24) against web (2).
