Disc corrosion has emerged as an important field of study within the brake community due to the diverse friction materials that are currently used in each market, and their inherent differences in terms of rust cleaning. This work presents a methodology that incorporates both dynamometer and vehicle tests into the investigation of the impact that different friction materials have on corrosion-induced brake judder —both at system and vehicle levels— during the removal of rust.
