Abstract
This document amends the Federal motor vehicle safety standard on hydraulic and electric brake systems to extend the current minimum performance requirements and associated test procedures for parking brake systems to all multipurpose passenger vehicles (MPVs), buses and trucks with gross vehicle weight ratings (GVWR) greater than 10,000 pounds (4,536 kilograms) equipped with hydraulic or electric brake systems. Currently, the only vehicles with GVWRs greater than 10,000 pounds to which the standard's parking brake requirements apply are school buses. The agency concludes that it is in the interest of safety to require all MPVs, buses and trucks with GVWRs over 10,000 pounds to have parking brakes that meet the performance requirements currently applicable to heavy school buses.
