What type of brakes are commonly used in larger vehicles, like trucks?

Larger vehicles, such as trucks, commonly use air brakes due to their effectiveness in managing the considerable weight and stopping power required for these vehicles. Air brakes function by using compressed air to operate the braking system, providing strong and reliable braking performance, which is crucial for vehicles that may carry heavy loads. The system allows for a more controlled and powerful braking action compared to conventional hydraulic brakes used in lighter vehicles.

These brakes are also advantageous in terms of heat dissipation and can maintain performance over prolonged use, such as during long-distance travel or when descending steep grades. The simplicity of the air brake system further aids in maintenance and reliability, making it a preferred choice for commercial vehicles.

Disc and drum brakes can be found on larger vehicles as well, but they are generally part of specific applications or auxiliary systems rather than the primary braking system. Hydraulic brakes are more common in passenger vehicles due to their effective and sensitive response in lighter applications.
