In this study, the thermo-elastic effects of frictional heat generation in a disc brake system due to\nbraking actions were simulated. The mathematical model that defined the problem was developed\nfrom the kinetic and potential energies of moving vehicles on the gradient surfaces. This problem\nwas solved for the selected geometry of disc brake and pad with their material properties selected\nfrom existing literatures using the finite element method and the computational results were obtained.\nThe thermal deformation obtained was in good agreement with similar literature results.\nAlso, for the same braking period and conditions, the results showed that a vehicle ascending a hill\ngave a higher temperature rise, Von Mises stress and thermal deformation on brake contact surfaces\nthan when descending hill. Therefore, the braking period required to bring a moving vehicle\nin ascendent motion to a lower speed is expected to be shorter because of the gravity effect than\nhorizontal motion, while descendent motion requires longer braking period.
