What is the Best Trailer Brake Controller?

best trailer brake controller

Heavy trailer loads put additional stresses on your tow vehicles brakes. This added stress can, over time, lead to breakdown or failure. If you’re towing heavy or awkward loads, like an RV or tiny house, trailer brakes are highly recommended.

There is nothing more unnerving than trying to stop a heavy load while approaching a busy intersection full of traffic, and having your trailer pushing you forward from behind as your brakes struggle or fail to slow you down quickly enough. Trailer brakes help you avoid these stressful and extremely dangerous situations.

WE had our team test and review the best trailer brake controller models to keep you safe on the road. Here’s a quick look with our detailed reviews below.

Two Main Types of Brake Controllers

Trailer brake controllers come in different types. They differ in several aspects such as appearance and even in their functionality. All these types of trailer brake controllers can be classified into two broad categories i.e. Proportional and time delayed brake controllers.

Time-Delayed Brake Controllers

Time delay brake controllers allow the driver to select how much braking force they want on the trailer. That force is generally arrived at by estimating how much the tow load is, and then setting the controller to compensate via the “Sync” function.

Because the force applied will be a static (the same amount of force each time the brakes are used), it’s important to set a time-delayed brake controller carefully. If set too low the tow vehicle will still take the brunt of the braking load. If set too high you put a lot of stress on the trailer wheels.

Proportional Brake Controllers

Proportional brake controllers are linked in to the pressure applied to your brake pedal, and apply a relative force to the trailer brakes. If you step lightly on the brakes, you get a light braking response from the trailer. A heavy foot gets a heavy response. This controller essentially allows the trailer brakes to operate as dynamically as car or truck brakes. There is less guesswork, it’s easy to use, and is considered the safer of the two types.

The Different Between Proportional And Time-Delayed Trailer Brake Controllers

The time delayed brake controllers are normally more pocket-friendly compared to the proportional brake controllers.

The Time-delayed controllers usually work by sending the same braking power to the trailer brakes whereas proportional brake controllers vary the braking power based on how quickly the tow vehicle is stopping and this produces a smoother braking action.

Time delayed brake controllers cause more wear and tear on either the trailer or the towing vehicle’s brakes because one or the other will be doing the majority of the braking while Proportional controllers reduce wear and tear by spreading the braking power evenly.

Time-delayed brake controls are can be mounted in any position and at any angle whereas Proportional controllers should be mounted within a specified range to work efficiently.

With time, we really need a delayed brake controllers no calibration whereas some models of proportional brake controllers require calibration to work efficiently.

Always smaller and slimmer compared to proportional brake controls.

Time-delayed controllers are more suitable for casual use. Proportional controllers are best put to work when the trailer is towed on a regular basis because they work well in diverse towing conditions and produce less wear and tear on the braking systems of the tow vehicle and the trailer.

It’s quite safer with proportional brake controls than with time delayed brake controls. This is because Proportional brake controls have the ability to automatically supply up to full power if the tow vehicle makes an emergency stop.

Things To Consider When Selecting a Brake Controller

When selecting the best trailer brake controls, you should do it diligently because when you get it wrong a lot of damage can be done both to your finances and to your vehicle. There are several factors to consider when choosing the best brake controller for your travel trailer. Some of them include:

What you will be towing

When you are planning to tow fragile goods or heavy-duty loads, you should consider proportional brake controls. This is because whenever the trailers stop, the stops made are smooth hence little interference on the load and on your vehicle. It will take good care of emergency brakes.

When towing a relatively light trailer, you should consider using a time-based brake control. They are usually sufficient for this purpose. They are a bit cheaper and perform very well with lightweight loads.

How often you will be towing

If you will be towing frequently or commercially, it is recommended that you use proportional brake control. For occasional towing, we recommend you to choose the time-based trailer brake controller.


Specialized trailer brakes come with a mixture of electric and hydraulic. It’s advisable to have brake controls that provide this kind of capacity for it to work efficiently.


Voltage by far is the most important item. They usually exist in either 12V or 24V and must match the power source in the towing vehicle. The intended voltage for almost all controllers is 12-volt vehicles Unless mentioned as 24V.

Number of axles

The idea when created a trailer brake controllers is to match a specific number of axle assemblies on the towed trailer. All it takes is a measure of how much total power they can provide. If the controller shows it is ideal for 4 axles, it could be used on a single axle, tandem axle, or even triple axel trailers.

Display type

When it comes to the display type, LED is the perfect match for all brake controllers. It has a digital display and ensures power is delivered effectively

Proportional or non-proportional

Proportional brake controllers normally use different systems to sense when your trailer is dropping off and then utilize proportional power to the electric brakes.

Non-proportional brake controllers maybe time delay activated or even in a solid state. They normally apply a set amount of capacity to the trailer braking system at any given time.


Trailer brake controllers come in different brands and models with different prices. Proportional controllers are a bit more expensive than the time-delayed controllers. It’s always advisable to ensure that the features offered by each brand give you value for the money. Also, consider your preferences. You should not spend more than what you need. Go for quality, outstanding performance, distinctive and reliable features because cheap may be expensive in the long run.

Why Do You Need The Best Trailer Brake Controller?

Trailer brake controllers come in handy when handling the uncontrolled weight or even when moving downhill. Without them, the weight can push ahead posing a danger of damage and accidents. It is not only important to your truck but also other vehicles especially in the event that you can’t slow down or even stop in time.

An electric trailer brake control supplies electrical power from the towing car to the electric brake on a trailer. If your trailer possesses electrical brakes, you may need a real brake controller. Some of the other reasons why you need a trailer brake controller include:

  • To enhance safety Measures
  • Trailer brake controllers helps you control the vehicle easily

  • Trailer brake controllers have Automatic Leveling and they are easy to install.

From the purposes of trailer brake controllers listed above, one can see how important they are and why all trucks should have them.

How Do Trailer Brake Controllers Work?

When press the brake pedal on the trailer, the brake controller lets the trailer’s brake system detect how much braking power the trailer need to stop. It activates the magnet when the power comes from the brake controller. It gets attracted to the inside smooth part of the revolving brake hub. The rotating center then causes the magnet to revolve. When it turns, it causes both brake shoes to pass on and then apply the brakes.

When you install the trailer brake controller into your trailer, it controls the power that the magnet at the wheel will get.

The controllers normally include a direct connection to the battery for the actual power source. It has a link with the stop light, typically from the switch at the brake pedal. This helps the machine to determine what capacity to supply to the magnet.

How To Install Trailer Brake Controllers

Installation of trailer brake controllers should be done properly for them to function well. Trailer brakes operate in a similar manner as an emergency brake only that they are not cable operated instead they are made with a magnetic piston which pulls when energized, hence operating the brakes.

First when installing a trailer brake controller is to mount the brake controller in an area that easy to accessed. You can choose to place it under the dashboard and directly above your right leg; this keeps the brake controller in view, therefore, helping you to monitor any potential problem.

When you purchase a trailer brake controller, it comes with a user’s guide which contains instructions on how to install it. If you follow the instructions provided by the device’s manufacturer and you also know what you are doing, installing a brake controller will be a walk over. In case you are having a problem installing the controller brakes you should contact a professional to handle the installation for you.
