Disc brake noise continues to be a major concern throughout the automotive industry despite efforts to reduce its occurrence. As a major supplier of automotive brake components, Delphi Chassis is continually investigating means to reduce disc brake noise. In this paper, experimental and analytical methods are discussed which reduce the occurrence of automotive disc brake noise. Three general categories of brake noise are discussed. These categories are low frequency noise, low frequency squeal, and high frequency squeal. A general description of all three categories and examples of relevant solutions are presented.
