Abstract: A vehicle is disclosed. The vehicle includes a body. The body includes a forward end and a rearward end spaced from each other along a longitudinal axis. The forward end of the body defines an opening for allowing airflow into the body. The vehicle also includes a venturi brake duct assembly positioned relative to the opening to receive the airflow from the opening and to guide the airflow to a brake device for cooling the brake device.

Abstract: A vehicle braking component having a composite structure includes a brake core comprising an aluminum alloy, the brake core defining a core surface, a thermal barrier layer comprising a thermally insulating material, and an adhesion layer between the core surface and the thermal barrier layer to facilitate adhesion between the thermal barrier layer and the brake core. The adhesion layer includes a metal. The vehicle braking component includes a wear-resistant layer on the thermal barrier layer. The wear-resistance layer includes an iron-aluminum-silicon-zirconium alloy and defines a friction surface of the vehicle braking component.

Abstract: A brake rotor having a composite structure may include an annular body defining opposite friction surfaces of the brake rotor. The annular body may include a core made of an Al—Si alloy, a thermal barrier layer made of a thermally insulating material disposed on the core, and a wear-resistant layer made of an Fe—Al—Si—Zr alloy disposed on the core over the thermal barrier layer. The wear-resistant layer may define a first one of the opposite friction surfaces of the annular body.
