An automobile disc brake system is used to perform three basic functions, i.e. to reduce speed of a\nvehicle, to maintain its speed when travelling downhill and to completely stop the vehicle. During\nthese braking events, the disc brake may suffer of structural and wear issues. It is quite sometimes that\nthe disc brake components fail structurally and/or having severe wear on the pad. Thus, this paper\naims to examine stress concentration, structural deformation and contact pressure of brake disc and\npads during single braking stop event by employing commercial finite element software, ANSYS.\nThe paper also highlights the effects of using a fixed calliper, different friction coefficients and\ndifferent speeds of the disc on the stress concentration, structural deformation and contact pressure of\nbrake disc and pads, respectively. Results from the investigation could provide a better explanation of\nthe variation in contact pressure distribution and in turn squeal generation. Thus, this study provides\neffective reference for design and engineering application of brake disc and brake pad.
