Air disc brakes made standard

Peterbilt will make front-axle air disc brakes standard across its entire Class 8 truck and tractor line, Paccar VP and Peterbilt General Manager Bill Jackson announced March 30 at a truck show in Louisville, Ky.

The announcement capped a press briefing in which Jackson noted that Peterbilt capital investments of more than $30 million are paying off just as the trucking industry is entering a modest – yet sustained – economic recovery. He said MX engines with SCR emissions technology, aerodynamic truck designs such as the Model 587 and its natural gas-powered vehicle lineup all represent the largest product investment in Peterbilt history, Jackson said. “As a result, Peterbilt is uniquely positioned at a time when fleets are actively replacing worn out equipment, newer aerodynamic used trucks are beginning to fill used truck lots and the national freight index has shown steady gains over the past two years,” he said.

Jackson said the decision to offer front-axle air disc brakes as standard on Peterbilt Class 8 trucks is in preparation for enhanced federal stopping distance standards that begin in August and will mandate a 30 percent increase in braking efficiency for 6×4 Class 8 trucks. “Air disc brakes offer the shortest stopping distances in the market today and provide a compact design, minimizing weight, reducing maintenance and improving both vehicle and operator efficiency,” Jackson said.

Peterbilt also announced other new products, including a new Speed Control Management System that provides drivers with progressive, fuel efficient shifts while coaching drivers to drive more fuel efficiently; a new Model 382 vocational truck in both day cab and extended day cab versions; and an all-wheel-drive version of the Model 348 vocational truck.
