Parts and Accessories Necessary for Safe Operation; Automatic Brake Adjusters and Brake Adjustment Indicators

Final rule.
The FHWA is adopting a final rule requiring the use of automatic brake adjusters (ABAs) on hydraulically-braked commercial motor vehicles (CMVs) and air-braked CMVs manufactured on or after October 20, 1993, and October 20, 1994, respectively. This rulemaking is intended to: Ensure that the operational standards for brakes in the Federal Motor Carrier Safety Regulations (FMCSRs) are consistent with the manufacturing standards in the Federal Motor Vehicle Safety Standards (FMVSSs), Nos. 105 and 121, which now require the installation of automatic brake adjusters and adjustment indicators on certain CMVs manufactured on or after these dates; and improve the safety of operation of CMVs by reducing the incidence of brakes that are out of adjustment.
