What is a Trailer Brake Controller?

Trailer brake controllers are compact electronic devices that allow you to set up and control how and when your trailer brakes from inside your tow vehicle.

Units are usually dash mounted and have various features to enable you to adjust your brake settings to suit your driving style and trailer’s size and weight.

Do I Need a Trailer Brake Controller?

Without a trailer brake controller, your electric trailer brakes simply will not work. Most states require a brake controller to be fitted when towing a trailer over 3,000 pounds or one that weighs over 40% of your tow vehicle.

Even if you have a lightweight RV travel trailer, installing a trailer brake controller will ensure that your journey is safer and give you greater control over your driving. Using a trailer brake controller will also help to give you greater peace of mind when heading off on vacation down unfamiliar roads and on major highways.

Buy from Amazon

The P3 Trailer Brake Controller by Tekonsha is our best overall choice, tried, tested, and approved of by RVers up and down the country. With its true proportional braking system, this unit provides trailer brake control for up to four braking axles with a choice of electric over hydraulic or electric trailer brake mode.

A red flashing alert is displayed in case of no trailer brakes and the boost feature allows you to set different levels of customized braking to suit your trailer, tow vehicle, and terrain. It also boasts two Plug-N-Play Ports.

With five storable settings for different driver or trailer braking preferences, the P3 is easy to set up, while the snap-in-mounting allows you to easily remove and store your unit outside of your vehicle when it won’t be in use. The only disadvantage with this excellent trailer brake controller is that instructions on where and how to best place it inside your vehicle could be improved.

All in all, if you are looking for a highly reliable, practical trailer brake controller that is technologically advanced, yet easy to use, and reasonably priced, the P3 is going to be the best overall trailer brake controller on the market for you.

Pros – Things we liked
Easy-to-read LCD

Best Connected Trailer Brake Controller

CURT 51180 Echo Mobile Electric Trailer Brake Controller

Buy from Amazon

The 51180 Echo Mobile Electric Trailer Brake Controller by towing specialists Curt allows you to control all of your trailer brake settings directly from your smartphone – ideal if you frequently change vehicles or just don’t want to have to install a unit inside of your tow truck.

No tools are required, thanks to this model’s plug-and-play installation. The triple axis, motion-sensing accelerometer connects to your smartphone via Bluetooth. In the unit’s app, you are able to create multiple driver and trailer profiles for exceptional ease of use. If for some reason Bluetooth becomes unavailable, your trailer brakes revert to using the most recently programmed setting so your brakes remain fully operational.

Electric over hydraulic brake compatible, this smart trailer brake controller can also be used with ABS and cruise control activated. Easy to use and transfer from one vehicle to another, the main flaw in this otherwise exceptional trailer brake controller is that the rubber strap connecting the accelerometer to your vehicle is not infallible and may result in your controller falling from your vehicle and your trailer braking system rendered inactive.

Zip ties and duct tape can help provide extra security, although for the price of the Echo Mobile, a more professional, permanent solution should be available.

Pros – Things we liked
Control all trailer brake settings from your smartphone
Store multiple user and trailer profiles
Triple-axis, motion-sensing accelerometer
ABS, cruise control, and electric over hydraulic compatible
No-tool plug-and-play installation
Cons – Things we didn’t like
Rubber strap for the accelerometer needs improving

If you usually haul the same trailer or ones with similar weights, save yourself some money on the more expensive versions and opt for our value choice – the 90160 Primus IQ by Tekonsha. The proportional trailer brake controller works with trailers with one to three axles and is completely self-leveling, unlike older versions.

Thanks to its new Boost feature, you have the option to increase your trailer’s braking when towing heavier RV trailers. When backing into tough spots, you can benefit from this unit working proportionally in reverse for complete security.

Complete with a Plug-N-Play port for two-plug adapters and a snap-in dash mourning clip for easy removal when not in use, this model gives you all the essential features you really need for safely towing your travel trailer at a much lower price than the competition.

The only slight drawback is that it can be a little tricky to finely tune the recessed adjustment wheel, however, this is not a major issue by any means. All in all, the Tekonsha is a great value for money choice.

Pros – Things we liked
Self-leveling proportional electric brake controller
Digital LED readout

Choose between the two modes to suit your vehicle and terrain for a safer drive towing your RV.

Thanks to its three-axis accelerometer, you are free to mount the main unit in any orientation with accurate brake level sensing. Unfortunately, there is no mounting hardware included with the V2, although you won’t have to spend a lot extra, it is an inconvenience having to go out and shop for appropriate screws.

The CURT 51110 Venturer trailer brake controller product picture

Buy from Amazon

The Venturer electric trailer brake controller is a basic unit that uses a time-delay braking system for safe stopping, increasing your trailer’s brake pressure as you depress your tow vehicle’s brake pedal. This makes it a good purchase for lightweight single or double axle camping trailers, although it has the capacity to support models with up to three axles.

Easy to use, the Venturer has a simple ramp-up LED brake monitoring system. Compatible with cruise control, anti-lock brakes, and low voltage systems, it’s suitable for use with just about any standard travel trailer.

The manual brake slider button allows you to adjust your braking intensity, with an adjustable power toggle and ramp time. However, the controls are very sensitive which can make for difficult fine-tuning and you may have to spend a considerable amount of time before you’re happy with the results.

Versatile, you can mount it in your ride at any angle and it comes complete with an adjustable mounting bracket. Purchase Curt’s quick-plug harness that matches your vehicle’s configuration for a quick and easy setup with no leveling required.

On the whole, a good basic time delay trailer brake controller that is well worth the money.

Pros – Things we liked
Self-leveling controller with LED indicator

The triple-axis motion-sensing accelerometer ensures highly responsive, yet smooth stops. Compatible with ABS, cruise control, and electric over hydraulic, this trailer brake controller boasts high compatibility and stylish good looks.

While you can get plug-and-play installation by investing in a Curt vehicle-specific harness, the tiny wire connections are very fragile, so make sure that you are armed with plenty of patience before you attempt to install. Full review.

Triple-axis, motion-sensing accelerometer
Easily accessible manual override

Buyer’s Guide to Buying the Best Trailer Brake Controller

To make sure that you choose the best trailer brake controller for your rig, check out our comprehensive buyer’s guide and find out just what you need to keep an eye out for.


Trailer brake controllers are generally fairly inexpensive. Low cost trailer brake controllers can be purchased for under $75 and are often time-delay models or basic proportional versions. Expect to spend between $100-$250 to pick up a premium model with extra features, such as a Boost mode and self-leveling main units.

Spending more generally equates to a better looking unit that is less obstructive on your dash. In terms of performance, there is not really that much difference between mid-range and high-priced models, however, you may find that more expensive versions are easier to adjust and provide enhanced usability.

Size and Weight of Your Towable

The larger and heavier your towable, the more reactive your trailer brake controller will need to be. For large trailers make sure that your brake controller has enough capacity to operate all of your trailer brakes simultaneously.

While small, lightweight trailers can get by with basic time-delay brake controllers, for large RV trailers, you’ll want a proportional trailer brake controller that is easy to adjust with a boost function for downhill sections and changes in the weather.

The Capability of Your Vehicle

It is important that your vehicle has sufficient capacity to tow your trailer, regardless of the installation of a trailer brake controller. Exceeding your vehicle’s maximum tow capacity is extremely dangerous, so make sure that you know your vehicle’s limits.

If your trailer weighs over 40% of your tow vehicle’s weight, you will definitely need to ensure that you have a brake controller fitted to prevent your trailer from swerving and extending your breaking time and distances, potentially causing a major accident.

Easy to Use

While most trailer brake controllers take a little while for you to perfect your setting and get used to the user interface it’s important that your trailer brake controller is easy to use. If you suddenly need to boost your braking power in an emergency situation, you’ll want to be able to do so at the touch of a button.

While some RVers find the traditional push-button models with a small LCD to be the easiest to use, others prefer connected versions they can adjust on their smartphone. It all comes down to your personal preferences and what you find to be the most useful.


As your trailer brake controller uses electricity from your tow vehicle to apply power to your trailer brakes, it is important that your unit’s voltage matches that of your vehicle, or else your brake controller may not work correctly. Most units are either 12V or 24V, with some models able to run on either voltage. Make sure you verify before purchasing.

Number of Axles

Your trailer brake controller will have a maximum number of brakes that it can simultaneously operate. This can be given as the individual number of brakes or, more commonly, the number of axles.

Most models have a capacity between one and three axles or one and four axles which equates to between two to six or two to eight brakes. It goes without saying that your controller should have sufficient capacity to operate all of your trailer’s brakes.


Most displays involve LEDs of some kind, either figures to display your braking power and error codes, or different colored LEDs to adjust intensity. Much like ease of use, it all depends on your personal preferences which type of display you go for.

A minimalist colored LED display suits some users, whereas other RVers prefer a more traditional display or no display at all and to use their connected smartphone to access all of their trailer braking information and settings.


Your trailer brake controller will allow you to adjust various settings including braking intensity. It may or may not have a boost feature to quickly override your settings for a more forceful brake. Other settings may include the following:

  • Braking type – proportional or user-controlled.
  • Electric or electric over hydraulic settings.
  • Adjustable ramp time.
  • Self-diagnostic settings.
  • Adjustable braking intensity.

Controller Size

Unless you are thinking of purchasing a connected trailer brake controller to use via your smartphone, you’ll need to consider what size controller you want to fit on your dashboard.

Basic, older units are more bulky and may require you to drill holes into your dashboard. Newer, slimline models often have a larger main unit that is installed out of sight with a small, integrated control knob that sits on your dashboard.

Smaller models give you more placement options, although some RVers prefer more traditional-sized models with a display and push buttons.

Electric and Hydraulic Braking

Check what type of braking system your trailer has before choosing your controller. The best trailer brake controllers are able to operate both electric braking systems and electric and hydraulic ones. You will be able to switch over from one type of braking to the other in your model’s settings.

Tire Safety

Make sure that you take time to experiment with your new trailer brake controller to find the optimum settings for your tow truck and RV trailer.

Test your brakes and set the maximum braking power, then try it out in a safe space. Then test out your sensitivity levels until you are happy with your trailer brake reaction to when you hit your tow vehicle’s brakes.

Taking the time to optimize your trailer controller setting will improve your trailer’s tire safety, for smooth stops rather than jerky, sudden movements that when applied repeatedly could damage your tires.

Different Types of Trailer Brake Controller

When choosing the best trailer brake controller for your RV you’ll have to decide whether you want a proportional controller or a time-delayed controller. Here’s what you need to know.

Proportional Controller

Proportional controllers are considered to be the best type of trailer brake controller as they provide smoother stops and more efficient braking. They do, however, cost more than time-delay models.

Proportional controllers use accelerometers to sense changes to your vehicle’s speed. When you hit your brakes, the controller applies a similar amount of power to your trailer’s brakes in proportion to your vehicle’s momentum.

For example, if you brake on an incline, your controller will apply less power to your trailer brakes as you’ll be going slower, than it would on a decline where you would be moving more quickly.

Time-Delayed Controller

Less precise and not as smooth as proportional controllers, time-delayed versions are more basic in their operation.

When you press on your tow truck brake pedal your controller immediately activates your trailer’s brakes applying an increasing amount of pressure. This amount can be adjusted in your controller’s settings to better suit your trailer and driving style.

If you are on a tight budget, you may want to get yourself one of Reece Towpower’s highly affordable Brake-Evn Trailer Brake Controllers. Thanks to its compact, unobtrusive design with LED diagnostics and push button controls for easy adjustments, the Brake-Evn with its proportional braking system makes an excellent buy.
