In some examples, a system includes a conduit configured to receive a cooled air flow produced by an air conditioning pack of a vehicle, such as an aircraft, and deliver the cooled air flow to volume defined by a brake system of the vehicle. The conduit may receive the cooled air flow from one or more compartments of the vehicle and/or an environmental control system of the vehicle. The conduit is configured to deliver the cooled air flow to provide cooling to one or more components of the brake system, such as one or more rotor discs and/or one or more stator discs.
