The paper develops FE model of the disc brake assembly in order to improve understanding of the influence of Young’s modulus on squeal generation. FE model of the whole disc brake assembly that integrates the wheel hub and steering knuckle is validated using experimental modal analysis. Stability analysis of the disc brake assembly is accomplished to find unstable frequencies. A parametric study is carried to look into the effect of changing Young’s modulus of each brake components on squeal generation. The results indicated that Young’s modulus of components play a substantial role in generating the squeal noise.
