Under the consideration of the central importance of brake pads with respect to customer satisfaction, state of the art brake pad production and resultant component fluctuations are discussed. The influence of orthotropic elastic material properties on NVH behaviour is examined based on stability calculations carried out on actual series brake systems. A sensitivity analysis shows the necessity of developing methods and processes so that future production can achieve significantly tighter scatter bands. Derived from the presented results, the short and medium term goals of Porsche with respect to pad characterisation as well as production and quality assurance of brake pads are outlined.
