Abstract
Brake judder caused by uneven heat spots on brake disc surfaces is a major issue in improving vehicle quality. This is especially true for rumble that occurs during high-speed braking. In order to determine the excitation mechanism of brake judder, it is necessary to measure the dynamic brake disc geometry and temperature distribution during actual operation on the road. A noncontact sensor system, suitable for a high temperature environment, was used to monitor these parameters, making it possible to visualize heat spots transiently. The data obtained revealed the influence of pad and disc parameters on heat spot formation.
