Testing of Alternative Disc Brakes and Friction Materials Regarding Brake Wear Particle Emissions and Temperature Behavior

In this study, different disc brakes and friction materials are evaluated with respect to particle emission output characteristic features derived. The measurements take place on an inertia dynamometer using a constant volume sampling system. Brake wear factors of concepts in sizes determined compared, grey cast iron disc, tungsten carbide-coated carbon ceramic disc. were tested over section (trip #10) novel test cycle developed from the database worldwide harmonized Light-Duty vehicles Test Procedure (WLTP). First, brake along bedding process series trip-10 tests. tests performed starting unconditioned pads, characterize evolution emissions until their stabilization. addition number- mass-related (PM2.5–PM10), size distribution was determined. Another focus evaluation temperature ranges associated challenges use readings potential regulation emissions. results illustrate establishing universal procedure for control representative braking procedure. Using carbide coated discs discs, reduction potentials up 70% (PM10) could be demonstrated WLTP cycle. is primarily result high resistance but additionally influenced by pad composition contact area.
