Brake judder is a braking induced vibration occurring in different types of vehicles. One of the main cause generating judder is a abnormal brake disc deformation during severe braking conditions. It is believed that residual stresses may change the rate of disc deformation when the disc temperature is increased significantly. In this paper, we investigated the quantitative measurement method of residual stresses and presented the reduction method of residual stress.
