Automotive Engineering friction based components are usually produced from asbestos material which is not environmentally friendly. The brake pad was formed with periwinkle shell, palm kernel and coconut shell, cashew nuts powder as core materials, epoxy resin and harden eras binder and carbon as fiber brace, copper, zinc aluminum and cashew nut shell served as abrasives with filler from shoe rubber dusts. Ten different groups of samples with various grit sizes and different percentage compositions were taken to produced 20 sample of the brake pads. The materials were grinded using hammer Mill, sieved with sieving tray of 425 μm, 850 μm,1000 μm and 1100 μm mesh sizes to determine the micro structure of the particles sizing. The material was weighed out with digital weighing scale to have the correct mixture ratio that contains all the required constituent elements. Test results reveal that Sample A, with a smaller grit size of 425μm grits size of palm kernel, 1000 μm grit size of cashew shell, 1000 μm grit sizes of periwinkle and 425 μm grit sizes of coconut with other mechanical properties found in Table 2 gave the desired mechanical property, when compared to the conventional brake pads which serve as control.
