Brake squeal is largely accepted by Scientists and technologists as a major problem which is induced by friction induced vibrations. It is well accepting to be frequently occurring at a frequency above 1 KHz. This report is interested in the finite element analysis (FEA) and experimental modal analysis (EMA) of a commercial disc of the brake system. The modal analysis has been used in this work to determine the natural frequency and mode shape pattern. The destination is to predict the squeal at the former phase of invention using a more realistic model. Firstly, the FE models of the disc brake parts were produced using 3D solid element. The experimental modal testing technique known as an impact hammer test has been held away to obtain modal parameters of the disc brake structure. The FE model is validated by comparing experimental results of the brake components. It is ground that good correlation is achieved in the dynamic properties of the brake parts.
