A brake is a mechanical device which slowing or stopping a moving object or preventing its motion. This work deals with the thermal analysis of disc brake of a vehicle. Heat generation and dissipation of disc brake are analysed. The objective of this project is to investigate and analyze the temperature distribution of rotor disc during operation using Ansys. The standard disc brake two wheelers model using in Ansys and done the Thermal analysis and also calculate the Heat flux, Temperature of disc brake model. This is to understand the pressure force and friction force on the disc brake material, which can help to reduce the accident that may happen in each day. In this project propose, design of a disc brake is proposed with copper liner on its brake disc, the heat transfer of existing and hybrid disc will be calculated for finding the effectiveness of heat transfer.
