The invention provides a production process for a brake pad added with modified nanometer graphene. The production process comprises the following steps: all raw materials are prepared; copper fibers and bamboo charcoal fibers are mixed in molten rosin; the raw materials are mixed to feed in a flour mill for powder milling; a semi-finished brake pad is obtained through mold pressing; the semi-finished brake pad is heated for molding; the molded brake pad is put in a closed container, then, the closed container is vacuumized, the vacuum state is kept by 30 minutes, and nitrogen is put in the closed container for keeping pressure by 10 minutes; the brake pad is heated to reach 60-70 DEG C, and is put in the closed container when the brake pad is hot, and argon is put in the closed container for keeping pressure by 10 minutes; and the brake pad is dipped by 15 minutes in a solution mixed by glacial acetic acid and tartaric acid according to a ratio of 1: 1. The prepared brake pad is higher in wear resistance, is prominently enhancedin heat wear resistance, is high in anti-aging capacity, is excellent in impact resistance, and is lower in thermal expansion and cold shrinkage rate.
