        Brake Drum is one of the most important part of vehicle, which is used to stop the vehicle. It is usually used in rear wheel because it does not have linear output comparing to caliper with rotor system. But it is still well used in many markets due to its cheap cost and good braking performance. In this thesis, drum stiffness is mainly dealt with. Stiffness, Material, Dimension, Balance, FRF are all important elements for brake drum design, but especially stiffness is highly related to cylindricity transformation and sometimes when it is weak, it can cause many kinds of drum related noise and judder. Each key dimensions of drum were considered as control factor of drum stiffness and each key combinations of these control factors were used to compare drum stiffness which is calculated by CAE analysis using ABAQUS. Via DFSS tool, we concluded which dimension is main contributor of high stiffness drum and how we can increase drum stiffness just slightly changing each key dimensions without mass increase.
