A Disc brake is a device that retards/halts the rotation of a shaft/ wheel. A disc brake system consists of a brake disc, a brake caliper and brake pad. When the brake pedal is applied, pressurized hydraulic fluid squeezes the brake pad friction material against the surface of the rotating brake disc. The result of this contact produces friction which enables the vehicle to slow down or stop. Due to this friction, heat will be generated and the brake disc gets heated up which affects the performance of the disc brake under different braking conditions. In this paper focus is primarily emphasized on the comparative performance of disc brakes having different profiles, by determining the von-misses stress, deformation developed & Maxi heat dissipation in the brake disc for different braking conditions using ANSYS14.5. In this work Gray Cast Iron & Structure Steel disc brake material use for calculating von-misses stress & deformation. The standard disc brakes two wheelers model using in Ansys and done the Modal analysis & calculate the Stress, deformation & Maxi heat dissipation. This is important to understand Stress, Deformation & Heat dissipation on the disc plate, how disc brake works more efficiently, which can help to Increase life of the disk plate & to find best profile structure of the disk plate.
