Abstract
A method for manufacturing a brake fitting comprising a plurality of studs each surrounded by a less fragile belt, the studs being non-contiguously secured to a metal support. According to the method, the support is provided with a slip-resistant surface by coating with a braze welding suspension which is oxidized and reduced. Stud blanks then are molded and compacted from powdered friction products and belt blanks are molded and compacted from metal powders and given an internal diameter 1.005 to 1.05 times the external diameter of the stud blanks, and the belt blanks are disposed around the stud blanks and sintered, obtaining sheathed stud blanks which are placed on the slip resistant surface of the support, and welded thereto by heat treatment. Finally, the sheathed stud blanks are forged at over 400 degree C., shortening them by at least 15%.
