In this article, we present to you the best electric trailer brake control systems for your vehicle and provide you with some extra information to help you understand these systems and decide on the best option for your needs.

On this article, we provide a lot of information related to trailer brake controllers. We suggest you read from the beginning to the end if you are new to trailer brake controllers but if you already have some knowledge, feel free to use the navigation menu below.

Benefits of Using a Trailer Brake Controller 

The main and possibly the only benefit of using a trailer brake controller is safety. Safely driving with a large object in tow is ultimately the reason for installing an electric brake controller. Apart from this benefit, the other benefits might come from specific makes and models that might suit you subjectively more.

Considerations When Buying Trailer Brake Controllers 

The first consideration is the size and weight of the trailer. The larger and heavier the trailer, the more control you will gain from using a proportional inertia sensing controller. Smaller trailers would benefit from a solid-state controller.

Mounting location is the next consideration, and the rule of thumb is that the controller must be within easy and full reach of the driver so the driver may initiate a brake without endangering the road.

The next consideration is the number of axles on your trailer. You will find that most controllers are limited to some axles, so make sure your model covers all axles on your trailer.

Check your trailer’s electric system, some come with a hydraulic over electronic component and this requires a special hydraulic over an electronic controller.

Power is a key consideration, you need to know if the system is a 12 or 24-volt user.

Frequency of usage should also be taken into consideration, where frequent towing would prefer an inertia sensing (proportional) unit, while an infrequent tow would prefer the solid-state (time delay) devices.

Types of Trailer Brake Controllers 

  • Time-Delayed Brake Controllers

Time-delayed brake controllers are solid-state models that are the most inexpensive devices in this category. This is the preferred controller for infrequent users and can be mounted at any angle. These models require you to set the power level, the onset delay and the length of braking to meet the load requirements. The difference between the car brake and trailer brake can cause jackknifing issues when driving erratically.

  • Inertia-Based Brake Controllers

These controllers adjust the braking power concerning the load/trailer based on a relational pendulum positioning. The pendulum movement increases relationally to abrupt braking, and the inertia based system increases the braking power to adjust for the pendulum movement. This method maintains a better balance between the trailer brake and the vehicle brake.

  • Proportional Controller

A proportional controller applies accelerometers to sense braking intensity. Based on the intensity, it delivers a proportional level of power to the trailer brakes. This method maintains an equal braking condition between the trailer and the towing vehicle. With this level of performance, you pay more and need to mount with accuracy.

  • Hydraulic-Over-Electronic Controller

The hydraulic-over-electronic controller is a more recent addition to this market, and it mixes an electronic response with a hydraulic transfer creating a more accurate and reliable response. While they are new, they are not necessarily the most expensive.

How to Install a Trailer Brake Controller? 

  • Step 1: Ensuring the Safety

Disconnect your vehicle battery negative cable. It’s always safer to work with no electrical current when installing electrical devices in your vehicle.

  • Step 2: Mounting Location

Determine where you need to mount the controller. Mounting is dependent on your vehicle type. In most large trucks and SUVs, you would place this to the side of the steering wheel, making the LED display easy to see. In some models, it might sit above the dash in full view. If you have any other devices attached to the dash, you should consider bunching this next to them.

  • Step 3: Mounting Fixing

Take your mounting hardware and mark the drill holes in the location you want to install your controller. When drilling, always be careful of under-dash wiring, so when drilling, it’s best to drill a marker only and not push all the way through. Then, using your screwdriver uses the locational hole as a guide point. Your screw will screw in easily since your dash is usually plastic.

  • Step 4: Installing the Controller

Fix the controller into the fixture and secure it using the bracket bolts. Make sure it’s secure and tight, but don’t overtighten.

  • Step 5: Plug and Play

Once your controller is secured in its bracket, take the wiring harness plug your brake controller into the wiring harness and the controller, creating a direct link between them.

Frequently Asked Questions

1. Do I need a Timed or Proportional Controller?

The proportional controller is far better than the timed brake controller. While the timed-brake controller does allow you to sync, it only ramps the brakes progressively. The proportional controller uses a sensor that detects the towing vehicle’s speed and braking and then mimics the status to the trailer brakes, essentially making the trailer part of the vehicle.

2. How Do I Mount and Install a Trailer Brake Controller?

As stated above, in brief; you first locate the mount, then connect it to the location surface. You then mount the controller into the bracket, and finally, you connect the controller to the wiring harness.

3. How can I Calibrate my Controller?

Proportional controllers are self-calibrate. Time-based controllers include an instruction manual that describes the calibration process. If you don’t have a manual, you can look it up online with the make and model of your controller.

4. How do I connect heavier trailers?

All towed trailers or caravans that weigh more than 2,000kg GTM must have built-in break-away systems and brakes fitted to every wheel. The break-away system must ensure that the trailer detaches from the towing vehicle automatically when the brakes are applied for over 15 minutes. Brake away systems are brake controller safety devices that are fitted to the trailer and contain their own power source.

5. How do Caravan Electric Brakes Work?

Most caravan brake hubs have brake shoes rather than disc brakes, and these are activated via magnetic control. The magnet is controlled by electricity and this is where the controlled comes into play. An electric controller is what activates the disk shoe magnet and applies the relevant pressure.

The main features of the electric brakes are the voltage range they can handle, and there are only two voltages to consider; 12 and 24. Never mix them up. The number of axles is just the number of points your controller can interface with, so don’t buy a controller that cannot handle the total number of axles in your caravan or trailer, and the more axles the thicker the wire you will need.

Electric-Hydraulic braking systems apply electricity and control to a hydraulic solenoid, it’s just another component that is used in recent developments and applies a more accurate control over the brakes than the standard magnetic ones.


If you have a trailer or caravan, or if you intend to buy one, you must buy an electric brake controller. This is a must if you want absolute safety in your ride. For small trailers or infrequent towing you might forgo adding this device, but if you are using a medium to a large trailer or any sized caravan, even when towing infrequently you must add a controller.
