In order to study the brake squeal issue of an SUV disc brake, a complete finite element model (FEM) for contact coupling of disc brake is established by using finite element software. The validity of the FEM is verified by the experimental modal analysis method. The complex eigenvalue analysis method is adopted to predict the instable mode of the system. The influence of friction coefficient, brake rotation speed, brake pressure and disc stiffness on brake squeal is further analyzed.
