Best Trailer Brake Controller Buying Guide

Time-delayed vs Proportional controllers

Time-delayed controllers work in a quite simple manner. As it does not rely on any part to sense the braking, the installation process is easier than the process for a proportional controller. For a time-delayed brake controller, the braking power applied to the trailer is fixed so depending on the situation you may notice that the stopping process won’t go that smooth.

As for proportional controllers, the stopping process is way smoother as the braking power is applied at a rate to match the towing vehicle deceleration speed. But the installation process may be a bit tricky as it may require a certain installation angle.

However, some people tend to pick time-delayed controllers over proportional ones because the time-delayed ones are cheaper. If you are going to use the controller just a couple of times a year it would be better to consider time delayed ones not only because these controllers are budget-friendly but the installation and removal process is much easier. 

Choosing right

As you already know, you have to choose the product carefully as in the worst-case scenario, a wrong choice may cause harm. Looking for the right product is quite hard these days with that many types of controllers available on the market. However, I prepared for you the most important things you have to take into account before purchasing the trailer brake controller. 

Brake boost

Brake boost can be quite a helpful feature in unexpected situations. Emergency stops can be quite difficult while towing heavy trailers, but in these cases, the device will detect the heavy breaking and it will apply a boost (about 5 – 10 %) to the braking power making the trailer stop faster and in a safer manner. It is recommended to use brake controllers that provide brake boost while towing heavy trailers.

However, not all controllers provide this function, braking boost being more common on proportional controllers.

Number of axles needed to be controlled

Unfortunately, not all controllers are able to handle more than three axles. However, if your trailer has two or three axles you are lucky, you won’t need to spend your time finding a controller that can handle that number of axles (because all of them can). But if you are on the other side and your trailer has four axles you need to be careful when picking a controller, you should not try to use a controller with fewer axles control as it may be dangerous. 

Controller type

You can divide the controller types into two big categories, Proportional and Time-Delayed. It is wise to choose the type of the controller based on your trailer’s size and weight. Proportional controllers are more suitable for big-sized and heavy trailers (works on smaller trailers as well). Their superior system ensures a smooth and nice towing experience as the controller can detect deceleration and enables the brakes on trailer to match the car’s speed.

However, this type of controller is more expensive, and it has a difficult installation process. On the other side, time-delayed ones are cheaper, and their system is quite simple.

You set a percentage of braking power and that percentage is applied on the trailer when you are breaking. By using Time-Delayed controllers, stopping will be less nice and less smooth compared to stopping experienced with Proportional controllers. However, its installation is rather simple.

Consider a built-in screen

The screen won’t affect the breaking at all, but it can be quite useful because you can get live diagnostics. Controllers with built-in screens won’t be a challenge for non-tech persons as these are really easy to use.

Materials used

You should look for a controller that is made of durable materials as wear-off damages can’t be avoided, especially if you are going to use the controller on different tow trucks. It is preferred to look for controllers made of resistant materials such as corrosion-free metals and polymer plastics. 

Installation process

The controller should be relatively easy to install, especially if you are looking for a controller that will be used on different tow trucks. If you never installed a controller before, getting one with a more complex installation method will be quite a trouble for you and you may not even be able to install it or you can even break it.

However, if you are looking for a controller that won’t be used on multiple trucks, then you shouldn’t care that much about the installation process as you won’t need to move it from a truck to other that often. 


It is very important to choose carefully your brake controller as towing a trailer can be quite dangerous without proper equipment. The controller must be reliable as any malfunction can lead to unpleasant situations that can cause even harm. Also, the controller has to be suitable for your trailer, therefore choose one that can support the number of axles of your trailer (you can count the axles by counting the wheels on just one side of the trailer, the axle number will match that number).

Before starting on your trip, you should test if the controller is working properly on an empty road (if possible) and try to adjust it if you notice any strange comportment.
