For Better transportation there is need for cars manufacturers to provide good safety systems The brake system has become important active safety systems. The disc brake is a device for deaccelerating or stopping the rotation of a wheel. This work presents the analysis of the contact pressure at the disc interfaces using a detailed 3-dimensional model of a brake in FEM. Finite element (FE) model of the brake-disc is created using solid modeling Software i.e. Pro-E and Analyzed in ANSYS which is based on the finite element method (FEM). It also investigates contact pressure distributions at varying load. Due to rise in temperature the change in angular velocity and the contact pressure is also studied. Wear reduces the life of friction material. Due High wear, the frictional material needs to be replaced Continuously. Problems such as Continuous wear of brake pads and thermal cracks in brake discs are due to high temperatures. Continuously controlling the temperature and thermal and mechanical stresses are critical to proper functioning of the braking system. Cooling of Brake System is further an important aspect to consider for brake disc durability and performance. Different materials for brake pads is tested as compared with the existing one. Finally comparison between analytical results and result obtained from Ansys is carried out and all the values obtained from the analysis are less than their Permissible values. Hence on the basis of thermal and contact stress analysis best suitable material is suggested.
