- Content
- 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.
- Content
- 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.
