The production of automobile brake pad using cow bone as base material was carried in this study. Metal mould was made to produce automobile brake pad. The composition of brake pad was cow bone (50%), iron filings (25%) and palm kernel shell (25%) each with a particle size of 100μm. Proportion of Sodium Silicate used as binder was 20% of oven dry weight of mix. The produced brake pad was subjected to hardness, wear rate, flame resistance, coefficient of friction, and water absorption and density test. The obtained brake pad properties were hardness (94BHN) ,wear rate (4.12mg/m), flame resistance (8%), coefficient of friction (0.34), water absorption(3.86%) and density (1986kg/m3). The results was found to compare favouably with commercial brake pad (asbestos based), optimum formulation of laboratory brake pad palm kernel based (PKS) and bagasse based. The production of brake pad from cow bone was found to be very feasible.
