The stringent competition in automobile market of passenger vehicle segment exists on account of With respect to critical attributes like vehicle comfort, fuel efficiency, and cost. Noise, Vibration, and Harshness are of critical issues and largely depends upon a number of components in an assembly; their resonances ultimately leads to vehicle comfort. Brake squeal is the major factor for vehicle comfort since it has the wide frequency range from 1 Hz to 12 KHz. In this paper, various parameters like coefficient of friction, an interface between liner and drum, contributions of components to resonant, etc. affecting on Drum Brake squeal are studied. The interface between Liner and drum during braking condition can't have control. Reducing coefficient of friction result in adverse effect on Braking performance. So the finest way to achieve the squeal noise reduction by structural modification of components in the design stage for stiffening and adopting FRF quality check method before manufacturing.
