Understanding the operational procedure for a supplemental braking system in a tow vehicle is crucial for safe towing practices. These systems modulate the braking force applied to a trailer’s wheels, coordinating it with the tow vehicle’s braking system. For example, incorrect adjustment can lead to trailer sway or reduced stopping power.
Employing a supplemental braking system significantly enhances safety by reducing strain on the tow vehicle’s brakes, minimizing stopping distances, and improving overall control, particularly in adverse conditions. Historically, these systems evolved to address the increasing weight and complexity of towed loads, becoming essential for responsible towing.
