Air brakes are a key aspect of many vehicles such as buses, trucks, and trains to ensure safe and timely stops. However, there are various alternative ways to refer to this braking system such as compressed air brake, pneumatic brake, or even air compressor brakes in some cases. These terms all describe the same concept, that of the use of compressed air in brake systems. Additionally, some may refer to air brakes as a type of secondary braking system, as they are typically used for larger vehicles as a safety measure alongside other types of brakes such as hydraulic ones. Ultimately, regardless of the terms used, it is critical that air brakes are functioning correctly to ensure safe operation of vehicles.
