One of the functions of a brake system is to reduce or maintain the speed of a vehicle. The braking process generally converts kinetic energy into heat. While a direct contact brake system functions using friction, a non-contact brake system such as an eddy current brake (ECB) relies on eddy currents. As repeated braking increases the temperature of the brake components, it decreases performance and, in extreme cases, can result in brake failure. In an ECB system, heat typically accumulates in the conductor material used to generate the braking force. When a conductor material is repeatedly subjected to excessive heat, its properties change affecting braking performance. This has prompted to the use of liquid- and air-based cooling in ECB systems, both of which have their respective advantages and disadvantages. Therefore, this present review extensively investigates the potential of using these refrigerants in various types of ECB systems.
