We reported the measurement method of brake wear emission to know the material balance / particle size distribution and the technology to observe / analyse (element level) nano-sized particles at 2017 (EB2018-VDT-004) and 2018 (EB2019-EBS-011). From these studies, we were able to estimate that the brake wear emission was divided into four categories and found that most of the wear powders are agglomerated, and the particle diameter grows by repeated agglomeration. In this study, to make clear the generation mechanism of brake wear emission, we report a technique of deagglomerating agglomerated particles and analysing them with FE-SEM.
