Buyer’s Guide

What is a Trailer Brake Controller?

A trailer brake controller is a device that is mounted in a tow vehicle and applied to a trailer’s brakes to halt the trailer when needed. There are two types of brake controllers: proportional and time-delayed.

A proportional brake controller relies on an inertia-based sensor or so-called accelerometer. Once you start slowing down and hit the brakes, it stops the trailer’s brakes too. The advantages of proportional brake controllers are the ability to adjust braking power and simultaneous operation with a vehicle’s brakes.

A time-delayed brake controller requires the driver to set the brake power and the sync (how hard you are hitting the brakes). The brake power won’t reach the trailer’s brakes immediately after you applied the brakes. Normally, there is a delay between the moment you press on the brakes and the moment your trailer actually stops.

Time-delayed brake controllers are considerably cheaper in comparison with proportional ones, but they offer less efficiency and safety when towing a trailer.

How does a Trailer Brake Controller Work?

Basically, a brake controller helps the driver find out a vehicle’s speed and how much braking power is needed to bring a trailer to a halt. The built-in display monitors the connection and the voltage level. More advanced brake controllers have a self-diagnostic system that gives even more information about the trailer brakes. Based on that, the driver can estimate how fast the trailer is going and how hard they should hit the pedal.

Most states require having a trailer brake controller in a vehicle because the risk of collision is usually high when drivers try towing trailers without proper equipment. When choosing such a device, you should take into account the weight of your trailer. The heavier a trailer you drive, the more powerful a brake controller must be to handle towing safely.

How to Install Trailer Brake Controller?

Installing a trailer brake controller is easy even for green drivers. However, you should know the right place to mount it. The most advantageous arrangement is generally under a driver’s dashboard to keep the display in sight. However, not every trailer brake controller can be installed in any orientation. Proportional controllers are sensitive to driving and cannot be located upside down and must be placed only at specific angles.

If you know where to install the brake controller in your vehicle, you might be confused about numerous wires. This problem is typical for drivers who are only learning how to tow a trailer. Manufacturing companies typically care about their customers and try to provide users with the most detailed information on operation and maintenance. Your brake controller also has an instruction manual that you should read it attentively before getting down to set-up. Pay attention to the part which indicates where you should plug in each wire.

Follow the following steps to perform the installation successfully.

  1. First, you should check that the wires in the rear of your vehicle are connected.
  2. Mount the brake controller under the dashboard connecting each wire in the right place.
  3. Turn on the ignition and see to it that the display indicates the maximum gain. You can adjust it with the buttons if necessary.
  4. At last, you should mount a plug connector in the vehicle. Make sure it is solid and reliable.

How to Use Trailer Brake Controller?

After you’ve installed a brake controller successfully, you should set it up based on your trailer configuration. Whether you own the best electric trailer brake controller or a simple one, there are a number of easy steps to follow:

  1. Check the connection each time you are going to drive even when you are positive the brake controller is in good condition. Your vehicle with a trailer should be on a level surface with no other vehicles nearby.
  2. Now, you should calibrate the brake controller if it is not able to calibrate itself.
  3. If you own an intelligent brake controller, it allows choosing individual settings that help customize the device or adjust it to a vehicle. At this point, you should customize your brake controller if possible.
  4. After starting the ignition, the brake controller generates the maximum braking output. Here, you should tune it depending on your vehicle’s load size. In order to change it, you should hit and hold the brakes, then set the initial output.
  5. Now, you should drive a vehicle at a speed of about 25 mph to ensure the brake controller is tuned correctly. If you see the trailer cannot stop properly, enhanced the initial braking power.
  6. On the contrary, if your trailer stops moving too harshly, lessen the initial output level a bit more.
  7. Finally, most brake controllers have an ‘ON’ switch that lets the driver turn on the controller only when there is a need of it. This manual control is particularly useful when the road surface changes and you have to drive down a rough road. You should take a gravel road, for example, and test how you manage to stop your trailer in this case. Normally, the brake controller allows you to immediately adjust your brakes to a different type of terrain. This substantially reduces the risk of collision and damage caused by bad towing.
