Change Settings with User-Friendly Controls

Tekonsha Braken-evn brake controller LED display and buttons

The controls on the BRAKE-EVN are elegantly simple and user-friendly. Use the clearly-marked push-buttons to change the level of gain or boost. Gain lets you set the maximum amount of power that will be applied to your trailer's brakes. Typically, the gain (also known as output) is only readjusted when you experience changing road conditions or if the weight of your trailer changes.


The Tekonsha BRAKE-EVN also features a large LED display that's easy to see so you can check on your current gain setting with a glance, as well as diagnostic information.


Power Boost for Heavy-Duty Towing

The boost setting controls the aggressiveness of your trailer's braking, meaning how quickly the brakes reach the maximum braking level. You can adjust this when you're towing heavy loads and you need more umph to bring your trailer to a stop. Your tow vehicle doesn't need that much power to brake in time, but your heavy trailer does.


Depending on the level of boost, your trailer brakes can start at either 13 percent or 25 percent of the set braking output. What this means is that, instead of starting at 0, the brakes will start at 25 percent and get to 100 percent sooner. This keeps the trailer from pushing your tow vehicle forward.


If your trailer weighs less than your tow vehicle, no boost is needed. But, if you want your trailer to lead the braking, you can select level B1.


Boost Levels:

Approximate Gross Trailer Weight Boost Level Increase in Initial Power Output
Less than tow vehicle GVW B1 13%
Equal to tow vehicle GVW B1 or B2 13% or 25%
Up to 25% more than tow vehicle GVW B2 or B3* 25%
Up to 40% more than tow vehicle GVW B3* 25%

*Both B2 and B3 offer a 25-percent boost in initial power. But the braking curve for B3 is more aggressive than that of B2. This means that, even though you will start out with the same intensity when using these boost levels, you will get an overall more aggressive braking experience with the higher level. So if you use B3, you will reach maximum braking sooner than if you use B2.


To adjust the boost, use the blue push-buttons on the top of the BRAKE-EVN.


Automatic Leveling and Simple Installation

The self-leveling feature of the BRAKE-EVN ensures that the brake controller continues to function even as you drive up steep hills or through the mountains. You can mount it at any vertical angle, and the controller will level itself automatically. But keep in mind that the BRAKE-EVN must be horizontally level and parallel with the direction of travel to work correctly.


The included wiring harness plugs into the BRAKE-EVN at one end and then into the factory port on your vehicle at the other. No need to cut and splice any wires!


Note: See etrailer.com's exclusive 7- and 4-way brake-control installation kit (ETBC7 - sold separately) if you don't already have a 7-way plug at the back of your vehicle.


Proportional Braking

What is proportional Braking

The Tekonsha BRAKE-EVN brake controller comes equipped with proportional braking to give you the best towing experience. Proportional braking means that your trailer brakes mimic your tow vehicle's brakes. If you slam on the brakes in your vehicle, your trailer brakes will activate with the same intensity; if you brake lightly, your trailer brakes lightly too. The trailer's braking is in proportion to your vehicle's braking. This saves wear and tear on the tires and the brakes on both your vehicle and trailer.


The BRAKE-EVN uses an internal inertia sensor to detect how your vehicle is braking so it can send the right amount of braking power to your trailer. It measures the inertia of your tow vehicle and activates the trailer's brakes to slow at the same rate. The result is uniform braking across your towing setup. No push-pull action - just smooth, proportional braking every time.

Video Transcript for Tekonsha BRAKE-EVN Trailer Brake Controller: The Breakdown

Hi, everybody. Andy here with etrailer.com. And today, we're gonna take a look at this Tekonsha BRAKE-EVN proportional, trailer brake controller for one to four axles. Now, this brake controller activates your trailer brakes in proportion to your vehicle's braking action. It automatically adjust your trailer's braking based on the deceleration of your tow vehicle. And it activates immediately.

There's no pausing like with time delayed brake controllers. This controller will work with trailers up to four axles or eight brake assemblies. And it is designed for use with electric brakes only. Now, it automatically levels. The internal sensor detects deceleration even if the controller is not mounted level.

And it can be mounted at angles between -20 degrees and 70 degrees in the vertical plane. The boost setting is going to let you adjust the aggressiveness with which the brakes are activated. You can get full power output faster by pressing the plus button, as you see right here, to increase that activation speed, or achieve smoother braking by pressing the minus button that you see there to supply power gradually. This also has a built-in slide bar manual override. Now, this features an easy to read LED display to keep you informed of your trailer's braking.

The display is gonna show the gain setting when the control is activated. And it can also be used to check for connectivity with your trailer to determine your boost setting and to troubleshoot. It is short circuit protected. And let me pull out my ruler here just to give you an idea of its size. The overall width, we are sitting right at 2 3/4 inches wide.

And then the overall length, it's probably better to measure this way. I'm trying to measure the longest points of this brake controller. We're sitting pretty close to 4 1/4 inches long. Try it up here a little bit. Yeah, about 4 1/4 inches long. And then the thickness or the height, however you'd like to describe it, we are sitting right at an inch thick or an inch tall. Now, this is gonna be a quick and easy installation. The mounting bracket, as you can see here, and the hardware to attach the bracket to your controller and the bracket to your vehicle, that is all included. A plug-in vehicle specific brake controller adapter, which is sold separately, can be used for certain applications to reduce installation time. It is important to note that if a custom brake control wiring adapter is not available for your vehicle, one of the following will be required. And I have that on your screen there for you. A 20 amp circuit breaker for two to four brake applications, or a 30 amp circuit breaker for two to four, I'm sorry, for six to eight brake applications. And you see those item numbers for those circuit breakers on your screen. Also, I would like to mention that if you are in need of a seven-way plug at the back of your vehicle, check out etrailer.com's exclusive seven and four-way brake control installation kit. The item number for that is on the screen as well. Now, this does have a limited lifetime warranty. And that's gonna conclude our look today. I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me..

I needed a new trailer brake controller for my f250. The original one i wanted was out of stock, and William at etrailer helped me find one based on what kind of towing i do. Ended up with the tekonsha brake evn. I cant believe how much difference it made! Easy install and easy to setup and adjust for different trailers. Highly recommend the tekonsha brake evn

Good design/size. Had to run the blue wire in an overlay to the rear 7 way harness as my vehicle did not have any factory provisions for a trailer brake signal wire.

  • Troubleshooting Trailer Brake Assemblies that Are New But Not Strong
    Since you mentioned that your brakes are brand new it's very likely you have a set of self-adjusting brake assemblies that just haven't adjusted fully to the point of activating strongly. This is a very common problem actually and has a very easy solution. What you'll want to do is find somewhere you can tow your trailer slowly like an empty parking lot and the manual override lever of the brake controller several times. Each time you apply the override the assemblies will tighten slightly...

    It is possible to weld on a brake flange such as Brake Mounting Flange for 1-3/4" Round Trailer Axles - 2K # 4-34 for 1-3/4" round axles, but it takes a qualified welder and even then it can be difficult to accomplish. A better solution is to upgrade your current axles with something like Timbren Axle-Less Trailer Suspension System - Spindle w/Brake Flange - Regular Tires - 2,200 lbs # ASR1THDS01, or if you need lift spindles you can go with Timbren Axle-Less Trailer Suspension System -...

  • Which is Actually Better? a Proportional or Time-Delayed Trailer Brake Controller
    Proportional brake controllers like the Prodigy P3 part # 90195 are by far the better choice over time delayed. Proportional controllers use internal sensors to determine how hard your trailer brakes should be applied based on how hard they sense you are applying the vehicles brakes. A time-delayed controller applies a set amount of braking force that ramps up over a set amount of time and then stays at that force till the brakes are released. If you think about how often you apply the...

  • Could Draw Tite Brake Controller Cause Vehicle Battery to Drain
    It really shouldn't be the controller under normal circumstances. The brake controllers like the Brake EVN # TK63VR go into a sleep mode after several minutes of inactivity which would prevent battery drain. Also the small LED light of the controller wouldn't be able to drain a battery in a matter of a couple days. If the controller is staying active that could be caused by shorts on the wiring of the controller to the vehicle or even a short or corrosion on the 7-way connector. You could...
