The braking performance has become a very important factor for automotive manufacturers and passenger because of the safety requirements. In general, brake squeal occurrences can be reduced by decreasing the friction coefficient; however, the braking performances also decrease. The objectives of this project are obtaining the dynamics properties (natural frequency) of brake shoes and to propose a new modification design of the brake shoe with the aim of improving the performances of the drum brake and stability of squeal. A finite element model of the automotive components has been developed in the analysis to determine the dynamic properties, brake torque measurement and instability of the system. The data of the finite element model is validated by performing an experimental modal analysis. The result showed that the value of natural frequency, brake torque and contact analysis increased when using the new design of brake shoe.
