Abstract: In the present study, investigation of new materials to replace the asbestos has started to be considered. Brake pads used in automotive industry contain materials composed of more than ten different ingredients. In this study, the use of Rice Straw Dust (RSD) and Rice Husk Dust (RHD) has been investigated for assessing the tribological properties of brake pads. RSD and RHD both have silica in them which gives the pad materials a ceramic like behavior. To obtain RSD and RHD, rice straw and rice husk were grained after they have been dried. Different amounts of RSD and RHD were included in the brake pad mix along with the other regular ingredients. These newly formulated brake pads have been tested under Friction Assessment and Screening Test (FAST). Friction coefficient, wear rate and Scanning Electron Microscope (SEM) for friction surfaces were examined to assess the performance of these samples.
