Abstract

A brake is a mechanical device used in controlling the speed of a moving vehicle using a frictional material and dissipates the absorbed kinetic energy as heat to the surroundings. A new brake pad composition has been developed with the Cashew Nutshell (CNSL), Silicon Carbide (SC), Steel Dust (SD), Carbon Black (CB), Epoxy Resin and Hardener (ERH). Five different samples of varying constituents were made with two different sieve sizes for each sample was investigated. The result showed that sample D of the 100 μm with composition 55g of (CNSL), 15g of (SC), 10g of (SD), 5g of (CB) and 15g of Epoxy resin and hardener had the best properties. The Brinell hardness value, Coefficient of Friction, Porosity, Ash content, Density and Wear rate were 75.65, 0.3528 1.925, 45.6, 1.521 kg/m3  for 100 μm and 1.17  respectively. These values are acceptable, though the 75μm samples fared better in many of the test results but lacked in the aspect of density when compared with the other sieve grades.  This shows that Cashew Nutshell can be used as filler in the production of eco-friendly brake pads.
