A segmented air deflector for attachment to a tractor, the air deflector having pivotal panels for the selective redirection of air flow to impinge the forward face of a trailer to create drag to exert a braking effect. The selective redirection is provided for by three separate groups of segmented panels being the main pivotal panels, opposing segmented upper side pivotal panels and opposing segmented lower side pivotal panels. The use of wing members either fixed or variably mounted on or about the various panels to condition, and therefore better control wind flow, is taught. Additionally standardized components are disclosed to form segmented air deflectors have various longitudinal lengths for specific installation requirements.
