Paccar, Volvo recall trucks to fix braking issues

Volvo Trucks is the world's second-largest manufacturer.

Two of the world's five largest truck manufacturers have issued recall orders for North American vehicles in the past two weeks to address braking issues. Washington-based Paccar has recalled over 100 Kenworth and Peterbilt trucks manufactured last year, while the North American division of Sweden's Volvo Trucks has issued an order for 670 commercial vehicles, also built in 2014.

In Paccar's case, the issue is with the possibly improper torque of brake caliper bolts in trucks manufactured between July 21 and September 16. The affected models are the Kenworth K270, K370, T660, T800 and T880, as well as the Peterbilt 210, 220 and 320.

According to the National Highway Traffic Safety Administration (NHTSA), the bolts could loosen and reduce the brakes' effectiveness, increasing the risk of a crash. Dealers will inspect the bolts and adjust the torque as needed on a case-by-case basis. No timetable has been given for the recall yet.

Volvo VHD, VNL and VNM models made between January 9 and October 28, 2014, are being recalled to replace a faulty air brake actuator. An rubber diaphragm inside the actuator may be improperly attached, which could allow air to pass beyond the diaphragm to the parking brake section. There, the air pressure buildup could cause the brakes to overheat and potentially catch on fire. Owners can bring their trucks to be fitted with new actuators, if needed, starting on February 27.
