Abstract:
To provide a manufacturing method for a disc brake pad using a forming die to form a final inclined surface on a friction material, where the resulted friction material is entirely uniform even if the flowability of the powdered raw friction material is insufficient. The method for manufacturing a disc brake pad includes the steps of preliminarily forming a preliminarily formed product by pressurizing without heating the powdered raw materials in a metal preliminarily forming die, and forming the final inclined surface on the friction material using a metal forming die with an inclined surface, the step of preliminarily forming including forming a temporary inclined surface, having a larger angle than the final inclined surface of the friction material, on the preliminarily formed product at an opposite side thereof to be fixed to a back plate, and forming a recess portion on the preliminarily formed product at a side thereof to be fixed to the back plate.
