Brake pads are the most important component of the automobile braking system. The use of asbestos fiber is being avoided due to its carcinogenic nature that might cause health risks. In the present investigation, the brake pads were produced by varying (wt.%) constituents of the existing composition and new formulations were made with other friction materials. In this study, a new brake pad produced using walnut shell dusts and boron powders to replace petroleum coke and asbestos were investigated, respectively. Two sets of brake pads with 3.5 and 7% ratio walnut shell and boron dusts were produced using compressive molding. The brake pad samples were put in the water and oil for 24 hours. The physical, mechanical and tribological properties of the walnut shell dusts and boron powders based brake pads were evaluated and compared with the values for the commercial brake pads. Afterward, hardness was measured with Shore D device. The weight changes were measured by an assay balance. The brake pads with walnut pads were heavier than the brake pads with boron powders. The compressibility and shearing tests were performed according to the ISO 6310 and 6312 standards, respectively. Several mechanical and tribological properties were tested for tailored frictional samples, including hardness, friction coefficient (COF) and wear rate, while the details and changes of the friction surfaces were studied by using a scanning electron microscopy (SEM) and an energy dispersive X-ray microanalysis (EDX) spectrum. In future, the brake pad samples will be evaluated on a pin on disk following the procedure in an American automobile testing standard in the coming period.
