Summary:

Among brake vibration and noise problems, brake judder is a problem that automobile manufacturers and brake suppliers have researched for a long time. As luxury feeling and comfort are required expectations of newer passenger cars, improvement of judder performance continues to be an important concern.Judder is generally categorized into three different types. The first is the DTV (Disk Thickness Variation) type in which aggressiveness of brake friction material generates DTV. The second is the corrosion-type brake judder in which torque fluctuates due to corrosion-induced μ variation and surface damage. The third is the hot judder type in which torque fluctuates due to disk rotor distortion caused by high temperature.To accurately analyze causes for brake judder observed in the market, we have conducted detailed analyses on brake parts from the market. The results have helped us understand that DTV and corrosion have reciprocal effects, mutually impacting one another.Based on the analysis results of market parts, we will present some examples, applying our findings to brake judder simulations on the dynamometer
