COMPOSITE DISC BRAKE BACKING PLATE

摘要

A layered brake backing plate is provided made of stampings in which a softer, lighter metal core, such as aluminum, is sandwiched between skins of harder metal stampings, such as steel, to make a lightweight composite brake backing plate. The harder stampings are textured with integrally raised piercing barbs. By rolling or pressing, the barbs are made to embed in the core, locking the layers together.
