4. Braking Sensitivity
Braking sensitivity, in the context of supplemental trailer braking, refers to the degree of responsiveness exhibited by the trailer brakes in relation to the tow vehicle’s braking action. When operating with a supplemental device, the sensitivity setting dictates how quickly and forcefully the trailer brakes engage upon activation of the tow vehicle’s brakes. Higher sensitivity results in quicker and more aggressive trailer braking, while lower sensitivity produces a more gradual and less pronounced response. The device’s user interface allows manipulation of this parameter to achieve synchronized and stable deceleration.
For example, when towing a heavily loaded trailer downhill, higher braking sensitivity may be desirable to provide immediate and substantial supplemental braking force, preventing excessive reliance on the tow vehicle’s brakes. Conversely, when maneuvering on slick surfaces, a lower sensitivity setting can minimize the risk of trailer wheel lockup and maintain directional control. The proper calibration of braking sensitivity, therefore, is paramount for maintaining stability and preventing hazardous situations such as trailer sway or jackknifing. Drivers must assess road conditions, load weight, and trailer characteristics to determine the appropriate sensitivity level to ensure proportional and controlled braking.
In summary, braking sensitivity is an essential aspect of operating a supplemental braking system.

5. Activation Methods
Effective operation of a supplemental braking system relies heavily on understanding its activation methods. The method by which the system engages the trailer brakes has a direct impact on braking performance and vehicle stability. Two primary activation methods exist: proportional and time-delayed. Proportional systems engage the trailer brakes in direct relation to the tow vehicle’s braking effort. A more aggressive braking input from the tow vehicle results in a correspondingly stronger braking force on the trailer. This method generally provides smoother and more controlled deceleration. Time-delayed systems, conversely, apply the trailer brakes after a pre-set delay, and at a pre-determined force. This approach, while simpler, may not provide the same level of synchronization as a proportional system. The choice of activation method directly influences “how to use a brake controller” effectively, dictating the driver’s approach to braking and adjustment of system parameters.
For instance, consider a scenario where a driver is using a time-delayed system to descend a steep grade. The delay in brake activation can create a lag between the tow vehicle and trailer, potentially leading to a feeling of being pushed by the trailer. In this case, the driver might need to anticipate braking situations earlier and adjust the delay setting to minimize the lag. Conversely, with a proportional system, the braking effort is automatically modulated based on the tow vehicle’s deceleration, providing a more intuitive and responsive feel. This allows the driver to focus on steering and maintaining control without having to consciously compensate for braking delays. Furthermore, manual override features, present in most systems, offer drivers the ability to independently activate the trailer brakes in emergency situations or for enhanced control, regardless of the primary activation method. Familiarity with the specific device’s manual activation procedure is critical.
In conclusion, the activation method employed by a supplemental braking system is a fundamental aspect of its operation. Understanding the nuances of proportional and time-delayed systems, and mastering the use of manual override features, is essential for safe and controlled towing.
