Abstract
Many experimental studies on the different compositions of brake pads have been
carried out with the goal of providing sufficient wear resistance, stable friction and
acceptable environmental conditions. However, the variation of the coefficient of
friction and performance properties depends on it materials. The presence of different
types of brake pads in the Nigerian market today makes it imperative to make a clear
distinctions with regards to quality and performance. This study investigate the
quality characteristics of commercially obtained brake pad for light weight vehicles
with respect to their physical and mechanical properties. The vehicles considered for
this study were those with gross weight of between 1500 – 3500 Kg in Ilorin. The
brake pads of three different vehicle brands were procured and labelled A, B and C
respectively. The properties examined were Brinell hardness, tensile strength,
compressive strength, impact strength and coefficient of friction by following
standard test in each case. The results obtained showed that at 3000 Kgf, sample A, B
and C has Brinell hardness values of 117.15, 106.68 and 103.22 respectively. Sample
C has the highest yield force under tensile at 815.03 N followed by sample A at
520.87 N and sample B at 426.51 N. Under compression, sample B has the highest
yield force of 32.46 KN while sample A has 17.68 KN and sample C recorded 14.59
KN. The three test samples showed impact strengths of between 69 – 69.17 J with
sample B having the highest impact strengths of 69.17 J. The coefficient of friction
obtained ranges between 0.32 – 0.34. The results indicate non-uniformity in brake
pads composition in the study area and the local authority involved with
standardization needs to enforce strict adherence to standards
