Abstract: This research focuses on wear of disc brake by method of analytical and finite element. An SUV car of DD6470C disk brake selected. Factors which considered as input parameters, such as the maximum allowable speed of the car as a constant throughout the work and by varying applied brake pressure. Analytical of the distribution of contact temperature along in the radial direction of disc brake caused by applied heat flux solved by using the separation of the variable method. Finite element simulation for contact pressure and von misses stress using; ANSYS workbench for the case of the structural analysis of disc brake was done by applying brake pressure and angular velocity. But, the thermal-structural, the maximum -contact temperature value of disc considered in addition. The contact pressure and von misses stresses were calculated analytically and ANSYS workbench results were presented in contour plot and numerically. The result shows that contact pressure, Von Misses stress and wear increased by increasing brake pressure in the case of the structure. And also parameters increase as increasing of both brake pressure and contact temperature of the disc in case of thermal-structural in all aspects like contact pressure, Von Misses and wear.
