Abstract—In automobile in order to stop the vehicle motion frictional resistance is applied by means of device called brake. In recent years Engineers have been able to eliminate most of the noise generated in the vehicle. However to eliminate friction induced squeal in vehicle brakes is challenging task for automotive engineers. In automobiles Disc brake and wheel are attached together. When brakes are applied to the disc it slows down or stops the rotation of wheel. This motion is caused due to friction between disc and the wheel. Due to this large heat is generated and brakes become too hot which leads to ceasing of work since no much of the heat is allowed to dissipate. This kind of failure is called as brake fade. In order to improve heat dissipation in our experiment ventilated disc rotor is used to determine Disc squeal. Modeling of the disc is been done on Solid works and Modal analysis is done on ANSYS 13.0. Ventilated brake disc squeal is determined for cast iron and Carbon-Carbon composites. Comparison is made among these three materials and material which generates least squeal is determined and recommended. Maximum squeal was obtained at mode 6 for both the materials and the frequency squeal obtained was less then High frequency squeal (8 KHz to 16 KHz) squeal

Index Terms—Brake disc, Squeal, Natural frequency, Modal analysis
