Brake Lining Quality Test Procedure
- Ground Vehicle Standard
Published October 26, 2021 by SAE International in United States
The purpose of this SAE Recommended Practice is to establish a uniform laboratory procedure for securing and reporting the friction and wear characteristics of brake linings. The performance data obtained can be used for in-plant quality control by brake lining manufacturers and for the quality assessment of incoming shipments by the purchasers of brake linings.
The SAE J661 Recommended Practice was developed in the 1950s as a quality control test for friction material manufacturers. Since that time, significant variation has been found in test results, making it difficult to assign a friction coefficient identification per SAE J866. This revision specifies the permissible variation for recertification testing as compared to the original certification results.

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.
