The use of asbestos fiber is being avoided due to its carcinogenic nature that might cause health risks. A new brake pad produced using periwinkles shell particles to replace asbestos and thermoset resin as a binder was investigated. The periwinkles shell particles were varied from 710-125 µm. The surface morphology, wear test and thermal analysis of the samples were examined. The results showed that there was good interfacial bonding as the particle size of periwinkles shell decreased from 710-125 µm. The wear rate increased as the load and periwinkles particles size increased. The co-efficient of friction obtained was within the recommended standard for automobile brake pad. The temperature of maximal decomposition of periwinkle shell was higher than asbestos and many agro-wastes currently used in the production of brake pad materials. It means that periwinkle shell can withstand higher temperature than asbestos. The results of this research indicated that periwinkles shell particles can be effectively used as a substitute for asbestos in brake pad manufacture.
