Can the trailer brakes self-adjust?
The trailer brakes can be adjusted independently or require regular manual adjustment, depending on the specific model components installed on the trailer. A simple method to determine whether a self-adjusting device is to remove the wheel hub/brake drum from the trailer spindle and check if adjustable cables are passing through the brake assembly. If this situation exists, you have a self-adjusting brake assembly that will self-adjust when you apply the brake during everyday driving. Please remember that even self-adjusting brakes require initial adjustment after installing new equipment.
Otherwise, regular adjustments are necessary if the brake assembly requires manual adjustment (without needing to adjust the cables).
How to test trailer brakes
For the safety of ourselves, our goods, our horses, and others on the road, it is essential to be prepared for terrifying moments when cars turn or stop in front of tractors. If you are not 100% sure the trailer brakes are working correctly, you are not ready to depart yet.
Today, we will pay special attention to testing trailer brakes in electric braking systems, which can be found in typical dual-axle multi-purpose vehicles or horse trailers. Most trailers have two brakes on each axle, so you will have four brakes if you have a two-axle trailer.
Using the electric trailer braking system, you can also install a brake controller (also known as a brake box) on the tractor. When you press the tractor's brake pedal, the brake controller will supply power to the brake itself through the trailer plug.
The setting of the brake controller will determine how much braking power the brake pedal will transmit. The digital brake controller can be set to automatically override existing settings, providing you with maximum braking power in emergencies.
The problem is that during the test drive, it is not always easy to determine which (if any) trailer brake is working by simply pressing the pedal.
On the contrary, you may want to find a slider on the brake controller. It should be between 0 and 10. Otherwise, there will be an indicator light. If you do not immediately find the brake controller manual, please refer to it.
After finding the slider, slowly move forward and start gradually pulling the slider. When you move from 0 to 10, you should feel increasing resistance. If you don't feel too much or break as you approach 10 minutes, you know you have a problem.
Because this testing method bypasses the truck pedal, you can have a more accurate understanding of the trailer braking function. You will know that any resistance comes entirely from the trailer itself, not the tractor brakes.
If your trailer fails the braking test, it may be due to one or more common issues:
-Corrosion of wiring or brake components. This can sometimes happen if the trailer is parked for weeks or months at a time.
-Improper brake adjustment.
-Layered and/or grease-saturated brake shoes.
-Missing components, such as gap adjusters.
