Proportional Braking

With a proportional brake controller, you can get heavy-duty emergency braking, general braking, or slow-to-an-idle braking for your trailer automatically. The intensity with which your trailer brakes are activated and the rate at which they are applied are dependent on the deceleration of your tow vehicle. This means that, unlike time-delay controllers - which send the same amount of preset power to your trailer brakes every time - proportional controllers are able to adapt to every braking situation differently.

So, if you slam on the brakes in your truck, your trailer brakes will activate with that same extreme intensity. And if you merely slow down as you approach a red light, your trailer will gradually brake in the same manner.

As long as the BRAKE-EVN is properly mounted according to the included instructions, the controller will automatically level, sense the tow vehicle's deceleration, and adjust the trailer's braking accordingly. The result is uniform braking across your towing setup. No push-pull action - just smooth, proportional braking every time.

Power Boost for Heavy-Duty Towing

The BRAKE-EVN offers a boost feature that gives you more initial braking power for times when you're towing heavy loads. You can switch boost levels so that the power output to your trailer brakes automatically starts out at either 14 percent or 28 percent of the predetermined power setting.

So, if you boost the initial power so that your trailer brakes activate with 25 percent of the overall intensity at the start, the brakes will reach maximum braking faster. This is particularly beneficial if you are towing a heavy load because the intensity required to stop that load may be far greater than that needed to halt your vehicle. Therefore, sending out more initial power to the trailer brakes - and causing them to reach maximum braking faster - allows you to better control the trailer so that it doesn't push your tow vehicle before coming to a complete stop.

If your trailer weighs less than your tow vehicle, no boost is needed. But if you wish to set the boost so that your trailer leads the braking of your towing setup, you can select level B1. The following table gives an indication of when you might use the different boost levels and the power increases that they offer.

Approximate Gross Trailer WeightBoost LevelIncrease in Initial Power Output
Less than tow vehicle GVWB114%
Equal to tow vehicle GVWB1 or B214% or 28%
Up to 25% more than tow vehicle GVWB1, B2, or B3* 28%
Up to 40% more than tow vehicle GVWB2 or B3* 28%

* 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.

Safety Features

The BRAKE-EVN offers advanced safety features to prevent damage to various components of your towing setup. Integrated reverse battery protection shields the brake controller and your trailer's breakaway system from shorts.

If ever there is a time that you need to brake your trailer separately from your tow vehicle - when traveling down a steep incline, for example - the manual override lever is easily accessible. Pushing this lever engages the brakes on your trailer with full power.

LED Display

The BRAKE-EVN has a digital LED display to keep you informed of your trailer's braking. The display shows the gain setting when the control is activated. It can also be used to check for connectivity with your trailer, to determine your boost setting, and to troubleshoot.

Automatic Leveling and Simple Installation

Because this controller operates with an internal inertia sensor, it must be mounted between -20 degrees and 70 degrees in the vertical plane. The BRAKE-EVN must be mounted on a level horizontal (side-to-side) plane and must be lined up with the direction of travel for the internal sensor to function properly.

The automatic 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. Mount the controller at a vertical angle that is between 0 degrees (level) and 70 degrees, and the controller with level itself automatically.

Installation of the BRAKE-EVN requires that you either purchase a custom wiring adapter designed to plug into the controller or that you hardwire the controller directly into your vehicle. To hardwire the controller, you must remove the plug at the end of the integrated wiring harness.

Installation Accessories

For easier installation, a vehicle-specific wiring adapter (sold separately) is available for most newer trucks and SUVs. One end of the custom adapter plugs into your vehicle, and the other end plugs into the controller - no hardwiring required.

For even easier installation, a vehicle-specific wiring adapter (sold separately) is available for most newer trucks and SUVs. One end of the custom adapter plugs into your vehicle, and the other end plugs into the controller - no hardwiring required.

Note: If a custom brake-control wiring adapter is not available for your vehicle, one of the following will be required:

20-Amp circuit breaker (9506P - sold separately) for 2- to 4-brake applications

30-Amp circuit breaker (38630 - sold separately) for 6- to 8-brake applications

  • Troubleshooting Draw Tite Brake Controller that Shows 9 Volts Regardless of Override Lever
    Your brake controller is definitely shot at this point based on what you listed so it would be the correct time to replace it with something like the # TK63VR which is very reliable and great performing. Since you put 12 volts on the brake output circuit and the brakes aren't activating I'd suspect you have a short on the circuit somewhere. Did the connection spark at all when you made it? I would also recommend just checking over all of the wiring and seeing if you can find any cuts or...

  • Troubleshooting Brake Controller that Locks Brakes Up When Brakes are Touched
    Most likely the stop/turn circuit of your trailer wiring is shorting out to the brake output circuit which is causing the problem you are describing of the brakes wanting to lock up as soon as the pedal is pressed. You can test this pretty easily by putting on a blinker and if the brakes pulse with either side that would confirm it and it would be a matter of finding the exposed wire between the two circuits and insulating them better. If not then yes it would be time for a new brake controller...

  • Troubleshooting E.R. Code of Draw Tite Activator Brake Controller
    The ER code you are seeing on your Draw Tite Activator brake controller means it has an internal problem that can't be serviced and would need to be replaced. You might get lucky and be able to unplug it and plug it back in but most likely it would need to be replaced if that does not fix it. The Brake EVN # TK63VR is a great replacement for this as it will plug right in, is a significant upgrade since it has an inertia sensor to apply brakes smoothly, and is very reliable.

  • Does Draw Tite Activator and Brake EVN Use Same Brake Controller Harness
    The Brake EVN # TK63VR does use exact same harness as the Draw Tite Activator you have now so it would be a really simple plug and play install. The Brake EVN would plug right into the same connector as your Activator.

  • Troubleshooting Draw Tite Activator II Brake Controller that Stopped Working
    It's possible your Draw Tite Activator does need to be replaced but there's a couple easy things you can try. Try cleaning all of the pins of your 7-way as sometimes it's just some corrosion or dirt that causes this issue. You can also try unplugging and plugging in the controller to reset it. If it still doesn't work it would be time to replace it and the Brake EVN # TK63VR would be a really solid option.

  • Brake Controller Recommendation for 2012 Ford F-150 with 7-Way
    To install a brake controller in your 2012 Ford F-150 with the factory 7-way all you need is a brake controller like our Brake EVN # TK63VR and an install harness part # 22292 and you'd be set. The harness plugs into the back of the controller and in a port under your dash and you'd be set. The reason I recommend the Brake EVN is because it's a proportional brake controller which senses how hard you apply the vehicle brakes and applies the trailer brakes with a similar intensity and because...

  • Troubleshooting Draw Tite Activator IV Brake Controller that Only Shows Dot When Brakes are Replaced
    The single red dot on your Draw Tite Activator IV # 5504 normally is seen when you press the brake pedal and a trailer is not connected. When a trailer is connected it normally would start showing the output voltage of the controller. So for some reason your controller is not able to sense a connection to your trailer. What I would first try is cleaning the pins of the trailer connectors as most likely a bit of corrosion is preventing the connection from being made. Try that and also...

  • Trailer Brakes Only Working With Manual Override on 2011 GMC Sierra
    If your trailer brakes are only working when you apply the manual override the issue is commonly the red wire - the stop light switch. Make sure it is connected to the circuit that that only sees voltage when the brakes are applied. The issue with not displaying numbers does make me think that the brake controller may have hit the fritz and need to be replaced though, and this would be true if the numbers never display, even when using the manual override. For your 2011 GMC Sierra a great...
