Abstract
A method of making a brake friction pad which includes the steps of placing a sintered friction material into a retainer cup, heating the friction material and the retainer cup to a predetermined temperature in an inert atmosphere, and striking the friction material with a single blow of a predetermined force. This single blow increases the density of the friction material and establishes a metallurgical bond between the friction material and the retainer cup.
