Abstract
In a friction component for brakes, clutches and the like, a core member is adapted for carrying a plurality of friction pads or cups on either or both of its surfaces. According to this invention a cylindrical metal bushing is positioned in an aperture through the core member to contact the bottoms of friction pads on the opposite surfaces of the core. The bushing has annular projections at the ends that make contact with the bottoms of the friction pads and passage of an electrical welding current through the assembly affects welding of the bushing projections to the bottoms of the pads and rigidly secures them to the core member.
