Disc brake are subjected to a large amount of frictional force during its regular working. In case of hard braking the temperature of the brake disc rotor rises above 7000 C. High temperature results in plastic deformation of brake disc which to localized surface contact and development of hots spot. Hot spots develop large thermal gradient resulting in three possible outcomes: thermal shocks, low braking performance and low cycle thermal mechanical stresses which result in cracking of brake disc. An analysis of vehicle dynamics was performed to calculate the mechanical stresses developed in the rotor and to find heat flux equation. Heat flux equation was further used to estimate thermal stresses developed in the rotor. In order to improve braking performance by cooling of rotor, different fluids were used. Above results were simulated in ANNSYS software and the results obtained were interpreted with analytical results.
