A case study was performed on a motorcycle platform to resolve customer complaint concerning Brake Noise. The Brake Noise was classically characterized in the moan and squeal frequency bands. Brake moan was present on the rear brake system, mostly in reverse, and without brake apply. The primary frequency for moan was in the range of 270 - 280 Hz. Brake squeal was confirmed at multiple frequencies on both the front and rear brakes. The intent of this paper is to present the challenges as well as the correlation of automotive methods and countermeasures to resolve these issues. Modal analysis was performed both experimentally and analytically to establish the correlation and to define the modal coupling of individual and adjacent components. Dynamometer testing was performed experimentally by adapting and evaluating the auto industry noise screening standard procedure SAE J2521 .
