In this study, the effect of peanut shell powder content on the tribological properties of automotive brake pads was investigated experimentally. Brake pads are intended to be resistant to environmental conditions such as abrasion, friction, temperature and humidity. Therefore, brake pads are formed by a combination of materials with many different properties. In this study, four brake pad samples containing different amounts of peanut shell powder were designed and produced. The added peanut shell powder is balanced with the filler in the content and the amount of other components was constant. Samples were produced by conventional dry mixing method. A special design brake tester with a gray cast iron disc was used to determine the wear and friction characteristics of the samples. All tests were performed according to appropriate standards. According to the results obtained, the availability of peanut shell powder in brake pads has been evaluated and categorized according to its characteristics.
