Abstract: In this study, the use of cedar (cidrus) pine cone (CPC) dust along with boric acid (BA) has been investigated for assessing the effect on friction coefficient. CPC has resin in it. BA is a boron production which is widely used in boron glass production and in ceramic industry for increasing the heat resistant and forming abrasion resistant. Newly formulated brake lining material with five different ingredients has 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.
