Brake pad; as frictional filler material is presented. This was with a view to exploiting the characteristics of the
Asbestos; periwinkle shell, which is largely deposited as a waste, in replacing asbestos which has been found to
Periwinkle shell; be carcinogenic. Five sets of brake pads with different sieve size (710–125 lm) of periwinkle shell
Mechanical and wear particles with 35% resin were produced using compressive moulding. The physical, mechanical
