RSD - Reduced Stopping Distance
New Regulations for Stopping Distance
to Implement Began with 2012 Models
Requirements for RSD Materials
Currently there are NO Federal Motor Carrier Safety Regulations governing aftermarket friction materials or performance requirements. End users are not required to verify their vehicles met the new stopping distance requirements.However, ALL Marathon aftermarket friction materials will work fine on vehicles produced after the Required Stopping Distance date. Simply match the GAWR with the appropriate product, as you always would have. In most cases, the Marathon product will yield performance enhancements, including better lining life, less fade, less noise, and increased brake power.
