In larger RVs, air brake systems are commonly used due to their effectiveness and reliability for heavy-duty applications. Air brakes utilize compressed air to operate the braking system, which allows for more consistent braking performance, particularly under the significant weight and load conditions that larger RVs may experience. The system includes components such as air compressors, reservoirs, and valves, which work together to provide strong braking force while ensuring that the vehicle can safely stop.

Additionally, air brakes have the advantage of being less susceptible to overheating compared to hydraulic systems, making them ideal for long-distance travel and situations involving steep descents where continuous braking may be necessary. This capability is particularly important for larger vehicles, which require powerful and dependable braking systems to ensure safety and control while on the road.

In contrast, while hydraulic, disc, and electric brake systems have their own applications in smaller or lighter vehicles, they do not offer the same level of effectiveness for the demands of larger RVs that are typically heavier and require more robust braking solutions.
