The problem
Certain class 8 chassis fail to comply with requirements of federal motor vehicle safety standard no. 121, "Air brake systems." The installation of the additional axle(s), raises the gvw capability of the vehicle and therefore requires an increase in the parking brake performance to hold on a 20% grade in order to meet the requirements of the standard.
The fix
Dealers will modify the park brake configuration on these vehicles. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact mack at 1-610-709-3337.
