Filed:

May 4, 1976

Appl. No.:

5/683460

Inventors:

John P. Kwolek - Latham NY
William G. Urso - Latham NY
Trevor D. Jones - Latham NY

Assignee:

The Bendix Corporation - South Bend IN

International Classification:

B23K 1900

US Classification:

228162

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.
