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.
