Nearly finished with my gooseneck 18,000 GVWR trailer. All my etrailer parts arrived promptly and are of excellent quality.

So far, so good! This is one of those must have devices that we all hope we never have to use. The package arrived in a timely manner and today I will be installing it on my well used trailer.

The product is what I need for my mullins style trailer. Hopefully it never comes loose from my car. Thank you

last year we drove from maryland to louisville in our 1931 A towing our mullins style trailer. as we got to louisville a car pulled out directly in front of us. i hit the brakes , locked the brakes on the trailer and kinda aimed the car toward the 3rd lane. people in the 3rd lane gave me room and we avoided a bad situation. great product

Excellent delivery time and communication. The break away kit was as described. The installation instructions were a little confusing but I eventually figured it out. Works great. Also got LED clearance lights and I was impressed as to how much brighter they were than the regular lights with a bulb.

Ask the Experts about this Tekonsha Trailer Breakaway Kit

  • Trailer Break Away Kit Installation
    The Brake Controller itself is connected to the battery in the tow vehicle. The breakaway system battery is good for a month or two of inactivity before needing charging. The Break Away kit you looked at, the Tekonsha part # 2028 includes a charger that will keep the battery maintained during towing. The charger is supplied power by the 12-volt power circuit from the 7-way trailer connector. I will provide instructions that include a wiring diagram. You can see the instructions by...

  • Pulling Breakaway Switch Pin Causes Battery Box to Burn and Melt and Running Lights Stay On
    If things start to melt when you pull the breakaway pin from the switch then that indicates a bad short that we have to track down. It also sounds like somehow the trailer running light circuit is being tied into the brake and breakaway system wiring which it should not be; or that there was additional damage in the trailer side connector causing a short between the running light circuit and another circuit. A breakaway system has to be wired up a certain way. I have included a diagram...

  • Troubleshooting Trailer Brakes Damaged From Breakaway Pin Being Pulled and Sparks from Battery
    I'm really sorry to hear about the mishaps on your brand new trailer! When reading through your descriptions the first thing that comes to my mind is the possibility that there's an exposed wire somewhere along the trailer that's making contact with the frame. This is essentially powering the frame so that when you attach the ground cable it's creating those sparks (which is not normal). If this isn't the exact cause of everything, there's at least something going on with the factory...

  • Why Would Trailer Interior Lights Not Work with Breakaway System Installed
    Sounds like you have the 12 volt power circuit of your trailer either running to only your breakaway battery or only the trailer lights. Most likely the issue is the connection that you are making from the battery to the 12 volt system. Make sure that the connection is solid and allows both circuits to be active.

  • Compatibility of Breakaway Kit 2028 With Electric Over Hydraulic Disc Brake Actuator
    The Tekonsha Shur-Set III Trailer Breakaway Kit with Built-In Battery Charger # 2028 will absolutely work with two Dexter 12k Axles with electric over hydraulic disc brakes. The EOH brake actuator is the key to the braking, so the 12V battery will send that signal to the EOH and give the proper pressure to your disc brake calipers. This battery is rated for 5 hours. I've attached an article to assist as well as a schematic of the wiring to assist.

  • Troubleshooting a Trailer Breakaway Kit that Drains the Battery When White is Connected
    The white wire is the ground wire of the breakaway kits like part # 2028 that you referenced. When it is connected it is completing the circuit for the battery to the trailer wiring. The problem you are having would indicate that there is a circuit on your trailer wiring's 12 volt circuit that is drawing amperage from the battery. This shouldn't be happening unless your battery is run straight to the breakaway battery and not through the charger. I would recommend you check the wiring...

  • Do Trailer Breakaway Kits Use Separate Batteries
    The breakaway batteries on campers are dedicated batteries separate from any other trailer batteries like what comes with the Tekonsha kit part # 2028. For more info on breakaway kits check out the FAQ article I attached on them.

  • Why Can't Trailer Breakaway Kit Use Main Trailer Battery
    You'll want to use a breakaway battery kit. Reason being the smaller battery of the breakaway kits like the # 2028 are small enough that they can be kept at a full charge from the trailer wiring 12 volt power circuit and nothing else will be drawing off of it. Since the other battery of your trailer would be too large to be kept charged and will have other accessories draining it occasionally it just wouldn't be a good idea.

  • Right Brake Light Does Not Work After Breakaway Switch Installation
    That is odd that your right rear brake light does not work if they spliced the break away switch battery into your running light circuit. The brake lights and running lights typically run on two different circuits so it should not have been affected. I would recommend checking each of the connection points for possible cuts or frays to other wires nearby. It is possible that they may have accidentally cut or damaged a brake light wire creating a short that would cause your brake light to...

  • Recommended Breakaway Kit for Trailer with Eight Electric Brakes
    Since you have eight electric brakes, I recommend a heavier-duty breakaway kit that is compatible with quad-axles. You will need one with enough amperage to be able to apply the trailer brakes on full for at least 15 minutes A great option is the Tekonsha Shur-Set III Trailer Breakaway Kit with Built-In Battery Charger # 2028. This one is top-loading, but you can get the side-loading version # 20005 if you want. This is compatible with trailers that have 1-4 axles. I attached a review...

  • Comparing Tekonsha Trailer Breakaway Systems
    Tekonsha breakaway kit # 50-85-313 is an all-in-one type of set up in which the charger is integrated into the lid of the battery box. Kits # 2028 and # 20020 both have a separate external charger that is, to put it bluntly, better than the one integrated into the lid of the other kit. They are all good options though and I am certain you would be happy with any of the 3. I have included links to videos for all 3 kits for you.

  • Trailer Breakaway System Recommendation for a Tri-Axle Trailer
    If all 3 of the trailer axles have brakes you will need one with enough amperage to be able to apply the trailer brakes on full for at least 15 minutes. The Tekonsha system, # 50-85-313 will work with 1 to 3 axles. I have included a link to a video review for you. Another option is # 2028. I have also included a link to an FAQ article on installing a breakaway kit.

    We have everything that you will need to add electric brakes to your trailer that has a 3,500 lbs axle. It doesn't come in a complete kit but I will list the parts that you will need. A Brake Mounting Flange # 4-35 will need to be welded onto the spindle so that the brake assembly can be installed on the axle. The next step would be to install the brake assemblies.

  • Do Tekonsha Breakaway Kit with Charger, # 20020 and # 2028 Come with the Same Charger
    Both the Tekonsha Breakaway Kit with Charger, # 20020, and the Tekonsha Breakaway Kit with Charger, Clamp On, # 2028, come with the same charger. The only difference is how each system mounts to the trailer. Break away batteries require a special charger because they are smaller than a regular 12 volt battery. Trying to charge it just through the 12 volt circuit from a trailer connector can overcharge the battery. The charger prevents that from happening after the battery has been charged...

  • How to Add Electric Drum Brakes to a Top Hat Econo Angle Utility Trailer
    In order to install electric drum brakes on your Top Hat Econo Angle Utility Trailer you will need braking assemblies, hub/drums, a breakaway kit, and trailer wiring. For the braking assemblies, I recommend using the Dexter Nev-R-Adjust Electric Trailer Brake Kit part # 23-468-469 because they are self-adjusting which means you don't need to make continual adjustments for even pad wear. For the hubs/drums, I recommend using the Dexter Trailer Hub and Drum Assembly part # 84546UC3 because...

  • How Many Axles for use with Dexter Trailer Breakaway Kit?
    The Dexter Trailer Breakaway Kit # 34-285 is going to work on single or tandem axle trailers only. If you're looking for a breakaway kit that allows for triple or quad axles I recommend the Tekonsha Shur-Set III # 2028 ,which works for anywhere from 1-4 axles. It is a top loading system for easy access the 5 amp-hour battery from above and comes with a built in battery charger. The battery box is also equipped with the ability to add a padlock similar to # ML4140LH for extra security.
