Abstract: Squeal simulation and analysis methods have been significantly advanced. Evaluation and testing technologies have been noticeably improved, and reduction remedies and prevention measures have become more mature. Brakes have become much quieter. However, the recurring occurrence of disk brake squeal indicates that there are still many challenges ahead, and brake squeal is still an elusive quality issue. This overview provides a summary of some recent and current developments and discusses remaining challenges along with future technologies. In addition, it emphasises the real-world counter-measures for squeal reduction, elimination and prevention.

Keywords: automotive brakes; disk brake squeal; vehicle noise; laser metrology; vehicle braking; vehicle design.
