There is currently no requirement in place for aftermarket brake lining performance. NHTSA has indicated that the automotive aftermarket should take a proactive approach to come up with a standard test definition for lining evaluation. Many aftermarket manufacturers use dynamometer testing to evaluate lining performance, but there is currently not a common recognized method for on-vehicle lining screening. This procedure was created to provide a quick, on-vehicle test method for lining performance evaluation. This procedure is intended for use in passenger cars; multi purpose vehicles and light trucks with a gross vehicle weight less than 4535 kg(10 000 lb).
This document is Cancelled without replacement. Robust vehicle testing procedures already exist. For the aftermarket, available robust dynamometer procedures are utilized. To find and use older vehicles for J2624 vehicle testing is problematic. There are few requests for this SAE publication. Additionally, the testing agencies have had no requests to perform this test.
