The driver of a heavy vehicle bears tremendous responsibility for safety. The heavier the car you drive, the more crucial the effectiveness of the braking system, and the driver’s use of this. Air brakes best supplement heavy vehicles' drum brakes, the latter being better for heavy vehicles for several reasons.
Air brake systems use a much higher force and are more tolerant of small oil leaks than hydraulic braking systems. Mostly for heavy vehicles, an electronicbrake system is considered the superior option.
