About This Item

This SAE Recommended Practice provides a common method to measure wear of friction materials (brake pad assemblies and brake shoes) and their mating parts (brake disc or brake drum). These wear measurements apply to brakes fitted on passenger cars and light trucks up to 4536 kg of Gross Vehicle Weight Rating under the Federal Motor Vehicle Safety Standard (FMVSS), or vehicles category M1 (passenger cars up to nine occupants, including the driver) under the European Community’s ECE Regulations. As the industry continues to move toward new rotor coatings with an objective of zero wear, it is becoming more and more relevant the revision of the methodology SAE recommends in terms of wear measurements on brake components. This revision will be focused on exploring improvements that can ensure a more consistent way to measure rotor and pad thickness as well as review the possibility of improving the required resolution of the equipment used.
