Reducing squeal from brakes system has become a difficult task for brake engineers. To date, a large number of proposals have been implemented to reduce disk brake squeal but very few solutions have been done in drum brake assembly. In this paper gives the Solution to reduce drum brake squeal through geometrical and material modifications in drum brakes to suppress squeal. Simulations have been done with the help of ANSYS 18.0 workbench software. A three-dimensional FE model of an actual drum brake system is developed and validated. First, the baseline FE model is simulated to predict squeal and then several modifications are proposed. Brake squeal simulation is performed for modified models in order to check the suppression of squeal noise.
