This paper focuses on a design solution for contact optimization that reduces the brake squeal noise. A front disk brake system is used as an example for the investigation. In the former, the finite element method is used to analyze the relationship between contact location of pads and squeal index that means a real part of complex eigenvalue. Parametric studies are performed to find out the better friction surface shape. In the latter, a new approach is proposed. It takes distibuted spring model as contact stiffness between components, and then calculates sensitivity of each spring. The proposed method is applied to an automobile disk brake and shows the practical use.
