Affinia Group Inc. yesterday announced its public support of a brake rotor standard currently under review by the Society of Automotive Engineers (SAE).

An SAE subcommittee working on the standard has recommended the adoption of SAE Recommended Practice J2928, which details dynamometer testing and performance criteria for assessing brake rotor crack initiation and propagation during high-energy brake applications. The proposed practice, which applies to light-duty vehicles, has passed peer review within SAE, and the measure now waits final adoption by SAE.

In addition to its public endorsement of the proposed standard, Affinia has formally requested that the National Highway Traffic Safety Administration (NHTSA) adopt a federal vehicle safety standard for brake rotors based on the recently completed work by the SAE subcommittee.

“While we know that many aftermarket and original equipment manufacturers will voluntarily adopt the new SAE recommended practice concerning brake rotor integrity, creation of a NHTSA standard will assure universal adoption,” said Terry McCormack, president and CEO of Affinia. “The excellent work of the SAE subcommittee represents a broad industry collaboration that addresses key technical issues and lays the groundwork for a NHTSA standard.”
