Which type of brake system is common in heavy trucks?

Heavy trucks commonly utilize a combination of drum and disc brake systems due to their distinct advantages in different driving conditions. Drum brakes, with their ability to generate high braking force and withstand heat well, are particularly effective for heavier loads and in situations where there is a risk of brake fade. The sealed nature of drum brakes also helps protect the components from debris and water, contributing to their durability.

On the other hand, disc brakes provide superior performance in terms of heat dissipation, consistency, and responsiveness. They are especially beneficial in applications that require frequent stopping and starting, and provide better modulation. The combination of both systems allows manufacturers and operators to leverage the strengths of each, creating a braking system that is more efficient and reliable for heavy-duty applications.

By employing a combination system, heavy trucks can optimize safety, braking performance, and maintenance intervals, making it a practical choice for the diverse demands placed on heavy vehicles in various operating environments.
