The mechanism for managing a supplemental braking system in a towed vehicle involves a control unit installed in the tow vehicle. This unit allows the operator to adjust the braking force applied to the trailer’s wheels, synchronizing it with the tow vehicle’s braking. This synchronization is crucial for maintaining stability and control during deceleration. For instance, a driver might adjust the gain setting based on the trailer’s weight and the road conditions to ensure smooth and effective braking.
Proper operation of this system is vital for safety and preventing accidents. It reduces strain on the tow vehicle’s brakes, extending their lifespan and preventing overheating. Historically, these systems evolved from simple manual levers to sophisticated electronic devices that integrate with the tow vehicle’s braking system. This advancement reflects the increasing complexity and weight of trailers being towed.
