Sweden-based Haldex has pared down operations and continues on as a global manufacturer of brake systems for heavy trucks, buses, and construction and agricultural equipment. Its products include all primary components and subsystems used in air brake systems, such as air controls, actuators, disc brakes, and remanufactured products. It has production plants in North America, South America, Europe, and Asia. In mid-2011 Haldex spun off its Hydraulic Systems division into a separate, publicly listed company called Concentric. In 2011 the company sold its Traction Systems division to BorgWarner for approximately $205 million. Its remaining Commercial Vehicle Systems division trades under the Haldex name.
