Some embodiments are directed to a duct assembly for cooling a brake assembly of a vehicle. The duct assembly can include a hollow inlet section that is disposed at the vehicle sub-frame and configured to capture air from beneath the vehicle sub-frame; and a hollow intermediate section that communicates with the inlet section so as to form a contiguous channel therewith. The intermediate section can be disposed entirely within the vehicle sub-frame. A hollow outlet section can communicate with the intermediate section so as to form a contiguous channel between the inlet, intermediate and outlet sections. The outlet section can be disposed and configured to direct the air captured by the inlet section to the front end of the brake assembly to thereby cool at least a portion of the brake assembly.
