Abstract

The effects of silica sand of 50-180 μm, 180-355 μm and 355-500 μm on friction performance and grit embedment at brake disc and pad interface was investigated. Results showed that present of external hard particles caused higher friction coefficient due to higher number of smaller particles involved in mixing and changing the effective contact, while good friction stability was attributed to smaller grit particles and compacted wear debris. Grit embedment was greatly dependent on presence of compacted wear debris as most grits were embedded into compacted wear debris with embedment of 0.8% was observed for 50-180 μm, 2% for 180-355 μm and 3% for 355-500 μm. © 2014 Penerbit UTM Press.
