4.1 Conduct Brake Test:

After adjusting the trailer brakes on your semi truck, it’s crucial to conduct a brake test to ensure they are functioning properly. Begin by driving at a safe speed and applying the brakes firmly. Observe if the trailer brakes engage smoothly and bring the trailer to a stop without skidding or pulling to one side. Repeat this process a few times to get an accurate assessment of their performance. Adjust the brake control as necessary to achieve optimal stopping power.
