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.
