The importance of setting the correct trailer brake gain cannot be overstated. When hauling a trailer, it’s crucial to ensure that the brakes are functioning properly to maintain control and safety on the road. A trailer brake gain that is too low can lead to reduced braking performance, while one that is too high can cause the trailer to pull the tow vehicle. In this blog post, we’ll delve into the world of trailer brake gain and explore what it is, why it’s important, and how to set it correctly.

What is Trailer Brake Gain?
Trailer brake gain refers to the amount of braking force applied to the trailer in response to the braking action of the tow vehicle. It’s a critical component of the trailer’s braking system and is typically measured in units of pounds per square inch (psi). The goal is to set the brake gain so that the trailer brakes in sync with the tow vehicle, ensuring a smooth and controlled braking experience.
Why is Trailer Brake Gain Important?
Setting the correct trailer brake gain is essential for several reasons:
-
Improved braking performance: A well-set brake gain ensures that the trailer brakes in sync with the tow vehicle, resulting in improved braking performance and reduced stopping distances.
-
Enhanced safety: Proper brake gain setting helps to prevent jackknifing, which can occur when the trailer brakes too quickly or too slowly, causing the trailer to swing out of control.
-
Reduced wear and tear: A correctly set brake gain reduces the stress on the trailer’s brakes, leading to longer brake pad life and reduced maintenance costs.
-
Improved towing experience: A smooth and controlled braking experience is essential for a comfortable towing experience, reducing the risk of accidents and improving overall safety.
How to Set Trailer Brake Gain
Setting the trailer brake gain involves a combination of trial and error, as well as a thorough understanding of the trailer’s braking system. Here are the steps to follow: (See Also: How Much To Replace Brake System? Costs Explained)
Step 1: Determine the Trailer’s Brake Type
The first step is to determine the type of brake system used on the trailer. The most common types are:
| Brake Type | Description |
|---|---|
| Electric Over Hydraulic (EOH) | A system that uses electric signals to control hydraulic brakes. |
| Electric Over Air (EOA) | A system that uses electric signals to control air brakes. |
| Hydraulic | A system that uses hydraulic fluid to apply brakes. |
Step 2: Check the Trailer’s Brake Gain Setting
Check the trailer’s brake gain setting by consulting the owner’s manual or looking for a label on the trailer’s brake controller. The setting is usually measured in units of psi.
Step 3: Test the Trailer’s Brake Gain
Test the trailer’s brake gain by towing the trailer and applying the brakes gradually. Observe how the trailer responds to the braking action. If the trailer brakes too quickly or too slowly, adjust the brake gain accordingly.
Step 4: Adjust the Trailer’s Brake Gain
Adjust the trailer’s brake gain by turning the adjustment screw clockwise or counterclockwise. A clockwise turn increases the brake gain, while a counterclockwise turn decreases it.
Common Mistakes to Avoid
When setting the trailer brake gain, it’s essential to avoid common mistakes that can lead to reduced braking performance or even accidents:
-
Not setting the brake gain correctly: Failing to set the brake gain correctly can lead to reduced braking performance or even accidents.
-
Not testing the brake gain: Not testing the brake gain can lead to incorrect settings and reduced braking performance.
-
Not adjusting the brake gain regularly: Failing to adjust the brake gain regularly can lead to reduced braking performance and increased wear and tear on the trailer’s brakes. (See Also: What Is a Jack Brake? Explained)
