Abstract
A disc brake pad comprises an organic friction material layer and an organic backplate layer. Both layers are formed of pulverulent materials compacted into "green" preforms at a pressure of 80-150 bars, which are then placed in a mold where heat and pressure are applied to create the integral disc brake pad. Both layers use the same resin and they may even be of identical composition.
Claims4
A disc brake pad comprising an organic friction material layer and an organic backplate material layer integral therewith, characterized in that the backplate layer is an unbaked preform of compacted pulverulent material, the friction layer is an unbaked preform of compacted pulverulent material, each preform containing the same resin binder, and the brake pad is formed by placing both preforms in a mold and simultaneously applying heat and pressure to join the preforms into an integral disc brake pad.
