Friction material back plate design, manufacturing and consistent quality are some of the key attributes for better brake performance. Historically, the auto industry’s focus on back plate quality has been limited to drawing dimensions. Recently, vehicle manufacturers across the globe are tightening caliper performance criteria to achieve near zero drag for fuel consumption regulations and improved NVH to attract end customers. To meet these new stringent requirements, friction and back plate suppliers need to focus, in more detail, on how to improve the backing plate quality and better understand the interface characteristics of back plate/pad assembly to caliper performance. While many key characteristics of the back plate were identified in past assembly design process, there has been vague understanding to connect with caliper performance, thus, the definition of back plate quality has been limited to basic dimensional measurement.
