Tips on Choosing an Electric Trailer Brake Controller

Though the choice of brake controllers is pretty large, all of them have a limited set of characteristics. These tools prove to be both simple and complicated simultaneously. The simplicity is in their easy mounting and application plus these units fulfill only one function. The complexity lies in automatic calculation and application of braking pressures plus in the fact that the appliance takes responsibility for secure hauling. Here are the key things, which you need to pay attention to while seeking for a brake controller.

  • Type. As we have already mentioned, there are 2 kinds of brake controllers: proportional and time-delayed. The selection of the most suitable one depends on your requirements and budget. So, it’s the first thing you need to consider before acquiring such an appliance.
  • Brake Boost. It concerns proportional controllers more. If the tool feels that the heavy braking is occurring (like an emergency stop), it will employ a boost to the braking power. Though it’s only 5-10%, some additional power can be a great assist if you need to stop a heavy trailer safely.
  • Number of Axles. The number of axles, which it’s necessary to manage, can be counted pretty simple: count the number of the wheels on the trailer and divide that number by two. The majority of controllers cope with 2-3 axles pretty well. The choice of those, which are able to handle 4 axles, is much smaller. So, if your trailer features additional wheels, opt for the devices able to control 4 axles.
  • Screen. Though there are many versions of this product without screens for sale, only one such item is in our list, the one by Reese. This controller has a very attractive price and can be bought for even less than $30. So, we couldn’t ignore it while creating the list. Basically, brake controllers with screens make the driver’s life a bit easier. They are easily regulated plus we can see all the diagnostics data directly on the screen.


The Reasons to Use a Brake Controller

  • Security. Hauling a trailer is rather a risky business and every driver should follow safety rules. To make your journey safe, it’s better to mount a brake controller. When you haul a trailer, the braking specifications of your automobile can be seriously affected. After brake force is applied, a brake controller provides extra power by making the trailer brakes function properly. As this device is able to influence the wheels of both automobile and trailer, fast and easy braking is guaranteed.
  • Care of Vehicle Brakes. If you don’t use a controller, all the stopping power lies on your automobile’s brakes. It’s very dangerous as the car’s brakes aren’t designed to cope with a heavy trailer and actually any trailer at all. Thus, your brake system is always in danger. The brake controller is able to spread the braking power around both automobile and trailer. In such a way, your automobile’s brake system will suffer less.


A Guide to the Brake Controller Installation

Before installing a brake controller, acquire a wiring harness, which will plug into your automobile. If you don’t own a hauling kit, you will need to do some work with wires, including wires splicing. It’s advisable to have a digital multimeter for that work, which will test the electrical wires.

The entire job can be divided into following steps:

  1. Check if the automobile is pre-wired. Look under the dashboard and move away some interior panels. Inspect if there is a wire with “Electric Brake Controller” name.
  2. Connect or splice wiring harness. If you have a pre-wired automobile, connect the plug to the harness. If you car isn’t pre-wired, splice into the wiring.
  3. Screw controller under dashboard. The majority of brake control units go with brackets and screws. Just connect the wiring from the automobile to the one of a controller. After that, place the wires into an accessible location, though it’s important that they won’t get in the way.
  4. Make adjustments. After the device is mounted, some settings regulations must be made. Adjust the controller, taking into account the trailer weight and driving conditions. For instance, a fifth wheel will demand some extra regulations.



If you care about the security of your journey, you surely must acquire a brake controller. By having such an appliance, you will not only save your trailer and automobile from damage, but will also guarantee more safety for other road users. Moreover, it’s your legal responsibility. Though laws may differ in various states, the safety on road always remains the primary goal.
