What type of brakes are commonly found in large trucks?

Air brakes are commonly found in large trucks primarily due to their effectiveness in handling heavy loads and providing the necessary stopping power. Unlike hydraulic brakes, which rely on a fluid system and may not generate sufficient force for the significant weight of large trucks, air brakes use compressed air to activate brake pads. This system allows for more consistent braking performance, especially under the stress of heavy loads and long distances.

Additionally, air brakes are designed to provide safety features such as the ability to automatically adjust to varying load conditions and a fail-safe mechanism where the brakes engage if air pressure drops below a certain level. This reliability is crucial for large commercial vehicles that transport goods over long distances and deal with various road conditions.

In contrast, while hydraulic, mechanical, and electronic brakes can be effective in certain applications, they do not offer the same level of performance or safety that air brakes provide for heavy trucks and associated vehicles. Therefore, air brakes stand out as the most suitable and widely used braking system in this context.
