How to Set Trailer Brake Gain

How to Set Trailer Brake Gain : Ultimate Guide [6 Steps]

Trailer brake gain cannot be overemphasized. The brake controller controls the amount of power applied to the trailer brakes. This is significant because it will determine the trailer’s stopping or towing power.

By applying the brake pedal to the vehicle, the gain instructs the brake controller on how much electric current to apply to the electromagnets trailer brake. This is relevant because it indicates how quickly the trailer will stop.

But have you ever wondered what the steps involved in how to set trailer brake gain are? Owning a trailer brake controller will require you to know the term “trailer brake gain”.

It is always best to err on the side of caution and set your trailer brake at a higher setting if you are unsure of what gain control to set. Let’s explore this topic in the following discussion.

What is Trailer Brake Gain?

What is Trailer Brake Gain

The trailer brake gain setting is the amount of braking power applied to the trailer brakes. This power is supplied by an electric current and is measured in amps.

The brake controller determines how much electric current flows through the trailer’s brakes using a rheostat, like a dimmer switch for your lights. The higher you set the brake gain, the more electric current flows to the trailer’s brakes and the stronger they will be.

How to Set Trailer Brake Gain in Some Easy Steps

Trailer wheel brakes are usually set at a higher gain than the tow vehicle’s brakes. This gives the trailer extra stopping power since it does not have its engine to slow it down. If you don’t set the trailer brake gain high enough, the travel trailer could start to push the tow vehicle when you hit the brakes.

You’ll want to set your trailer’s brake gain so that it is just strong enough to stop the trailer without locking up the wheels or causing them to skid. Here are some easy steps to take to set your trailer brake gain:

Step 01. Connect Your Trailer:

You will need to ensure that your travel trailer is properly connected to your tow vehicle. All the electrical connections should be made, and the safety chains should be attached.

Step 02. Set Up Your Brake Controller:

Once your travel trailer is connected, you can set up your brake controller according to the manufacturer’s instructions. Try to mount it in a location where you can easily see the settings and reach it with your hand.

Step 03. Calibrate Your Brake Controller:

Many aftermarket brake controllers will need to be calibrated before they can be used. This is so that the controller knows how much electric current to apply when you hit the brakes.

If your brake controller does not have a calibration feature, you can usually find instructions on calibrating it in the owner’s manual.

Step 04. Test Your Travel Trailer Brakes:

After calibrating your brake controller, you can then test your trailer brakes. With the parking brake engaged, slowly apply pressure to the trailer’s brakes by pushing down on the brake pedal.

The brakes should engage smoothly and evenly. If they don’t, you may need to adjust the travel trailer brake gain.

Step 05. Adjust the Trailer Brake Gain:

If your trailer’s brakes are not engaging correctly, you will need to adjust the trailer brake gain. Simply turn the knob on the brake controller to the left or right until the brakes engage smoothly and evenly.

It is always best to start with a lower setting and then work your way up until you find the perfect balance. You don’t want the trailer’s brakes to be too weak or strong.

Step 06. Retest Your Trailer Brakes Again:

Once you have adjusted the trailer brake gain, you will need to retest the brakes. With the parking brake engaged, slowly apply pressure to the trailer’s brakes by pushing down on the brake pedal.

The brakes should engage smoothly and evenly. If they don’t, you may need to adjust the trailer brake gain again.

What is a Trailer Brake Controller & How Does it Work?

What is a Trailer Brake Controller & How Does it Work?

Trailer brake controllers are a device that is used to control the electric brakes on a trailer. It is usually mounted in the cab of the towing vehicle and is connected to the trailer’s brakes.

When the vehicle’s brakes are applied, the factory trailer brake controller sends a signal to the trailer’s brakes. This signal tells the trailer’s brakes how much electric current to apply. The amount of electric current is determined by the brake controller’s settings.

The brake controller has a few different settings that can be adjusted. These settings include:

  • Brake Gain: This setting determines how much electric current is sent to the trailer’s brakes.
  • Brake Delay: This setting determines how long the trailer’s brakes will stay engaged after releasing the vehicle’s brakes.
  • Brake Force: This setting determines how much force is applied to the trailer’s brakes.

These settings can be adjusted to suit your needs. For example, if you are hauling a heavier trailer load, you may need to increase the brake gain. Alternatively, if you are hauling a light load, you may need to decrease the brake gain.

It is important to note that the factory controller must be properly calibrated before it can be used. This calibration process ensures that the trailer’s brakes will engage properly when applied to the vehicle’s brakes.
