Abstract
A cooling mechanism for a brake assembly is provided. The brake assembly includes a brake rotor with opposing outer surfaces. Brake pads having a lining are arranged adjacent to the opposing outer surfaces as is well known. An actuator, typically a hydraulic piston, forces the linings into engagement with the outer surface to slow the vehicle thereby generating a significant amount of heat at the rotor/brake pad interface. Inadequate cooling of the brakes occurs because of the tight packaging of the brake components and limited airflow. To better dissipate the heat the brake pad lining includes a cermet matrix, which has a high thermal conductivity. By utilizing a cermet in the brake pad lining, as opposed to conventional compositions, substantially more heat may be extracted at the rotor/brake pad interface thereby improving brake performance.
