Do large vehicles typically have a different type of braking system compared to automobiles?

Large vehicles, such as trucks and buses, typically utilize air brakes rather than hydraulic brakes, which are more common in standard automobiles. Air brakes are designed to withstand the heavy loads and stress encountered by larger vehicles, providing a more effective and reliable braking system in these circumstances. The air brake system operates on compressed air to apply the brakes, offering a significant advantage in stopping power and safety, especially when additional weight is involved.

In contrast, most passenger cars rely on hydraulic brake systems, which use brake fluid to transfer force from the driver's foot to the brake components. While hydraulic brakes can be efficient for lighter vehicles, air brakes are specifically engineered to handle the demands of larger vehicles, making them safer and more effective on the road. Other systems mentioned in the options, such as mechanical or electronic brakes, are either less common in large vehicles or do not compare to the effectiveness and safety of air brakes for this application.
