Abstract: A method of manufacturing a stainless steel ventilated brake disc is provided that results in a relatively inexpensive stainless steel ventilated brake disc. In manufacturing the ventilated brake disc a pair of annular plate members are provided that are constructed of stainless steel. Then a spacing member constructed of stainless steel is inserted between the inner axially facing surfaces of the first and second annular plate members. A nickel bonding paste is applied at the points of contact between the spacing member and the inner axially facing surfaces of the first and second annular plate members. Heat is now applied to the spacing member and the annular plate members as a combined unit with the nickel bonding paste applied thereto. This heating of the assembled unit austenitizes the spacing member and the annular plate members and simultaneously bonds the spacing member to the inner axially facing surfaces of the annular plate members.
