Evaluation of Properties of Disc and Pad Materials and their Relation with Disc Brake Noise – An Experimental Investigation

The purpose of this paper is to generate basic data about physical properties of disc and pad friction materials, and then correlate these data with results of disc brake noise evaluations. It is attempted to predict how variations in some characteristics of friction materials could affect their propensity to generate noise. At the end of the study, the goal is to point out a way in which the properties of counter friction materials could be changed to reduce the brake noise propensity.
