A Study on the Countermeasure to EURO7 Brake Dust Regulation Phase 1

This is a case study to cope with the brake dust regulation of EURO7, countermeasures were listed, and evaluation and verification studies using C segment sports utility vehicle were conducted on them. Through this phase1 study, it was most reasonable to apply hard metal cladding disks and metallic friction material to front brake and apply friction materials as NAO with less dust generation to rear brake. This was because it is possible to satisfy new regulations without deteriorating the required performance in Europe. However, it is necessary to develop detailed specifications of discs and friction materials to satisfy our braking development goals for European models in the Phase 2.
