1. An apparatus for manufacturing a brake pad including a friction material and a backing plate which are coupled to each other, the apparatus comprising:
a forming device configured to form friction material powder in the form of the friction material and attach the formed friction material to the backing plate in a forming process;
a quality stabilization device configured to heat and press the friction material; and
a heat treatment unit configured to heat the brake pad at a predetermined temperature,
wherein the forming device includes an upper forming mold, a lower forming mold, and an intermediate forming mold positioned between the upper forming mold and the lower forming mold,
wherein the quality stabilization device includes an upper stabilization mold, a lower stabilization mold, and an intermediate stabilization mold positioned between the upper stabilization mold and the lower stabilization mold, and the intermediate stabilization mold has an accommodation space formed penetratively at upper and lower sides thereof to accommodate the friction material of the brake pad,
wherein the upper stabilization mold heats the backing plate to a temperature of 110 to 160° C., and the lower stabilization mold heats an end of the friction material to a temperature of 190 to 260° C., and
wherein the upper stabilization mold and the lower stabilization mold press the friction material with a pressure of 5 to 20% of a pressure applied to the friction material powder by the forming device and a time of 400 to 700 seconds.
