What can be used as a means of rapid cooling for hot brakes?

In the context of cooling hot brakes, portable fans are an effective means of rapid cooling. When brakes reach high temperatures, they can become a safety hazard if not cooled properly. Portable fans can provide airflow over the hot brake components, helping to dissipate heat quickly and safely. This airflow enhances the cooling process by increasing evaporation and convection, making it a practical approach to managing excessive heat.

Other methods, such as water hoses or CO2 extinguishers, could present risks or complications. For instance, using water on hot components can lead to thermal shock, potentially damaging the brakes or causing steam hazards. Fire blankets are primarily intended for fire suppression rather than cooling, and they do not effectively address the issue of high temperatures in the same way that airflow from fans can.
