Abstract
A brake pad backing plate made using powder metallurgy has an inner surface to which a friction material mass is attached and which cooperates with the mass to resist shearing of the mass relative to the plate. Formations can be made on the inner surface that resist shearing of the friction material mass from the backing plate, the mass can have mating formations and the plate can be steam treated for additional benefits.
