Friction Coefficient Identification and Environmental Marking System for Brake Linings
- Ground Vehicle Standard
Published January 16, 2012 by SAE International in United States
This SAE Recommended Practice is intended to provide a uniform means of identification which may be used to classify the friction coefficient of brake linings, based on data obtained from tests conducted in accordance with SAE J661 Chase Test and SAE J2975 Measurement of Copper and other elements in Brake Friction Materials. NOTE: It is emphasized that this document does not establish friction requirements for brake linings, nor does it designate significant characteristics of brake linings which must be considered in overall brake performance. Due to other factors that include brake system design and operating environment, the friction codes obtained from this document cannot reliably be used to predict brake system performance.
This SAE Recommended Practice is being revised to incorporate markings for environmental certification according J2975 of truck blocks, disc brakes, and drum brakes.

Brake Linings Standards Committee
The goal of the Brake Lining Standards Committee is to provide a means of developing and maintaining common test and nomenclature standards for the friction materials industry. In working toward this goal, the committee helps reduce industry costs, harmonize global markets and enhance safety by recommending uniform test and performance standards for automotive friction materials.

* Redlines comparisons are available for those standards listed in the Revision History that contain a radio button. A redline comparison of the current version against a revision is accomplished by selecting the radio button next to the standard and then selecting 'compare'. At this time, Redline versions only exist for some AMS standards. SAE will continue to add redline versioning with ongoing updates to SAE MOBILUS.
