Abstract
A method of coating disc brake pads to obscure and seal minor surface imperfections, thereby reducing scrap rates. A preform of friction lining material is coated prior to molding and curing the preform and bonding the same to the backing plate to form the brake pad assembly. The preform is coated with an aqueous composition containing a solids mixture of 5–50 vol. % resin and 50–95 vol. % non-resin solids. Advantageously, the coating composition has a 5–30 vol. % solids mixture content, which solids mixture includes 15–25 vol. % resin, 0–10 vol. % powdered elastomer, 5–15 vol. % carbon black, 20–50 vol. % inorganic fillers, 5–15 vol. % organic fibers and 1–10 vol. % inorganic flake material.
