Bendix updates whitepaper pertaining to stopping distance mandate

Paper presents in-depth look at mandate's industry impact and solutions to address it.

A subsequent section addresses how the federal mandate evolved, what it requires and its anticipated benefits. This is followed by a primer on foundation brakes, from the forms they take to the physics behind them. The paper also examines advances in braking technology.

The whitepaper describes the wide variety of configurations available to meet the mandate. Options include all drum brakes, all disc brakes or a combination of both. The solution most often implemented, the paper explains, is an upgrade of steer axles to higher performing drum brakes. While the drum brake solution allows fleets and owner-operators to meet the minimum federal requirements, the white paper emphasizes that for the greatest stopping power in all conditions and optimized vehicle safety, the clear choice is air disc brakes. The paper points out that, in general, solutions for RSD phase two emphasize a further increase in air disc brake usage, as well as drum brakes designed with additional technologies.

BSFB's study also includes an analysis of the mandate's impact across the industry, from OEMs to fleets, owner-operators, and the aftermarket, as well as an examination of the value proposition of higher performing brakes.

A new section in the updated paper looks at the importance of choosing OEM replacement parts, with the choice of proper replacement brake linings for high performance brakes being especially critical. Many fleets and drivers remain unaware that choosing anything less than like high performance replacement friction can negate the technological advancements of the brakes – and potentially compromise safety. As the paper describes, significant, widespread confusion about friction replacement exists in part because of the FMVSS 121 dynamometer test procedure, which is no longer the only requirement in the new RSD environment.

"The Federal Reduced Stopping Distance Mandate: Impact and Solutions" incorporates a technical glossary, illustrations, and diagrams, along with charts and data from NHTSA and the Federal Motor Carrier Safety Administration. It also includes quick takeaways, such as top-of-mind considerations when spec'ing a new truck or changing out a truck.
