NHTSA has been petitioned because of having no federal standards for either original equipment or replacement brake linings for air-braked vehicles. The documentation of the result of NHTSA research is significant for the examination of variability present in the Society of Automotive Engineers (SAE) recommended practice J1802 Brake Block Effectiveness Rating. Four SAE J1802 brake test fixtures were obtained from government and industry testing laboratories. Physical measurements were made on three of the major fixture components: the s-cams, spiders and rotochambers, in an attempt to identify geometric variations between fixtures. Two fixtures with two sets each of two types of brake lining blocks were then tested on a brake dynamometer. The geometric variances found from the physical measurements probably contributed only a negligible amount to the total variability of the effectiveness values measured during the dynamometer tests.
