The present invention relates to a technology of lightening a brake component such as a brake drum or a brake disk of a vehicle. The present invention forms a new type of the brake component by combining different kinds of materials using a different kind diffusion casting method and an uneven structure when manufacturing brake components formed of different kinds of materials, so that the present invention provides the lightweight brake component capable of improving performance, durability, and fuel efficiency caused by preventing the separation of a joint part and reducing a weight; and the reliability of the joint part between the different kinds of materials can be obtained. |
