Abstract
In the present study, wear and frictional behaviours of automotive brake pad sliding against GG 20 cast iron counter face have been investigated experimentally using a pin on disc type friction tester. Wear tests were carried out under dry conditions. A central composite design was used to describe response and to estimate the process parameters in the model. Empirical models have been developed to predict wear loss and friction coefficient as a function of contact pressure and sliding velocity using multiple regression. The statistical analysis show that the contact pressure is identified as the most dominant factor affecting wear loss, sliding velocity is identified is the most dominant factor affecting friction coefficients.
