The agency said the trucks are equipped with Bendix ATR-6 antilock traction relay valves that may leak fluid in temperatures below zero degrees and result in continuous brake application.
The recall includes Kenworth models T660, T700, T800 and W900 and Peterbilt models 384, 386, 387, 389 and 587. Paccar will provide a free temporary repair until Bendix delivers a permanent remedy.
Navistar said it had delayed International truck production until a permanent fix is available, and the company predicted the valve problem will contribute to a loss for the quarter that ended Jan. 31.
After postponing deliveries of vehicles affected by the Bendix part defect in January, Volvo began using another valve to continue building trucks at its Virginia plant. Volvo is working with customers to repair trucks already on the road.
Bendix notified NHTSA of the defect in January after receiving customer complaints about brake issues. The company said a permanent fix was forthcoming. Bendix estimated the part problem affected up to 60,000 vehicles.

Shell describes new oil category
Development is under way on creating new heavy-duty engine oils to be ready by January 2016 that will be used in new truck engines.
A new oil category dubbed PC-11, or Proposed Category 11, will be developed to help engine manufacturers meet federal standards for 2014-2018 model year trucks, said Dan Arcy, global OEM technical manager for Shell Oil Solutions. The new category will cover improved fuel economy and reduced greenhouse gas emissions.
Arcy is leading a team of oil industry technicians who will specify tests and standards for the category requested by the Engine Manufacturers Association.
PC-11, the first new category since CJ-4 was introduced in 2006, may include two subcategories, or separate oils, said Arcy. One will preserve heavier oil common in the industry now. The other will be a thinner oil better adapted to enhancing fuel economy while preserving durability.
Oil industry technicians will spend the next four years specifying standards to be ready for licensing by January 2016. Tests for the new oils will make sure they are durable and resist engine breakdown, while increasing fuel efficiency. But the lighter viscosity oil designed for fuel economy may not be compatible with older engines, Arcy said.
