  • Makes sure your trailer safely stops if it separates from your vehicle
    • When the pin gets pulled from the switch, a signal is shot back to your trailer brakes to activate
  • Battery charger ensures the system's battery is always charged
    • Prevents overcharging to prolong battery life
  • Mounts to your trailer jack post with included U-bolts
    • Can also be mounted to your trailer frame with self-tapping screws (sold separately)
  • Protects battery from rain and debris with durable, plastic case
    • Lid can be secured with padlock (sold separately) to deter battery theft

Note: A breakaway system is required by law in most states for trailers that are equipped with electric brakes and have a GTW of at least 3,000 lbs.


Quick Tips:

  • When you store your trailer, be sure to keep the pin plugged into the breakaway switch. If the pin's removed for an extended period of time, dirt and moisture can get into the switch and cause corrosion that could keep it from activating when you need it.
  • A breakaway system needs to be able to apply the trailer brakes fully for at least 15 minutes. In general, the heavier your trailer, the higher amperage battery you'll need for the breakaway.

The products were acceptable quality and the customer service was UNEQUALED, EXEMPLARY, GREAT, etc.

The trailer overhaul job went well and we hauled a capacity load almost 1500 miles in some difficult road conditions, stopping only for fuel and to sleep.

We'll use your products again.



by:

I have not installed this yet but have looked over everything I received with this kit. I couldn't be happier with the it. There are only a few pieces needed that aren't included and they are choice of electrical connectors and a seat tapping screw to attach the switch itself. Everything else is in the box. The instructions are clear and easy to understand. I will be attaching this to the trailer Jack on a 1962 Airstream Ambassador.



by:

I ordered electric brakes and breakaway kit I place my order on Wednesday afternoon and could have taken advantage of free shipping but to the option for 2 day delivery.because we are at the very end of reconditioning our flatbed trailer and I want it out of the shop the parts ordered arrived the next day matched up perfectly and the trailer is out of my shop and the next project is in. I buy all my trailer replacement parts at etrailer due to their prompt and courteous service



by:

Ordered this on Tuesday - arrived on Thursday... awesome delivery time!

Bought this to put on my 1996 Coleman/Fleetwood Shenandoah popup camper since for some reason ours didn't come with a breakaway kit. Wanted to mount the battery and charger box on the tongue of the trailer, but the supplied U-bolts that came with the kit will NOT go all the way around the rectangular frame rails of the trailer tongue. Ended up going to the local big-box hardware store and buying some threaded rod and made my own mounting brackets. Instructions included are very easy to follow. Only thing I saw that was missing in the kit that you'll need for installation was a package of tap-splice connectors for connecting the breakaway switch and the battery and charger to the existing trailer wiring.



by:

Order was complete and delivered in a timely manner. Only problem (minor) was the 7way pigtail was not wired to color code. Had to use test light to get 3 of the wires in correct location. Could be a problem if someone wasn't comfortable with ringing out wires.



by:

Great products with fast free shipping (large enough order. I just installed the tow package on my suburban and it was easy when following the videos. It was nice to have everything already gathered and ready to go. Not having to go but ring terminals, wires, zip ties, screws and testers made a daunting project simple.



by:

Easy enough to install. Put it on a home built trailer. Can't say that I've had to use it but it seems to be built well enough. I did check it after install and it applied the brakes but I was in the drive way and not going down the highway at 50+ MPH. And hope I don't ever have to use it in those circumstances.



by:

Top shelf products, excellent selection, awesome prices. Converting a tandem trailer to electric brakes, these guys had it all from bolt on coupler to the new drums! Love these guys!



by:

Outgoing, helpful, easy to talk to. Very quick to help and solved problem. Made process extremely easy. Thank you so much, very happy and satisfied customer. Second time around shopping at etrailer . Definitely will come back for future orders ! Thanks again Juanita for everything!



by:

Great pricing and i appreciate that it's made in U.S.A. One of the brake adjustment tension cables arrived detached from its swedge end.I just re-crimped the end and all went together smoothly. I will definitely will use E-Trailer again.



by:

Great service and delivered 3 days early!
Have
ordered parts from etrailer several times and ALWAYS had good results
The parts I ordered this time was cheaper than ANY other web site and fast delivery
I live in rural Montana so can't get some parts local
I recommend etrailer every time



by:

A few minor adjustments but it is on now! Abigger clamp for my trailer would have been better, but replaced it with another one that I purchased.



by:

The products I purchased were as stated with no problems or missing parts. The delivery was expedited at no additional cost which allowed me to complete my trailer ahead of schedule. The staff were helpful and displayed an interest is assuring that my order was taken care of personally. Well done!



by:

Rebuilding a utility trailer, this break-away box will fit perfectly for the installation.



by:

Everything arrived within 3 shipping days, installation simple and clean. Even though it was by email, customer service interaction was extremely impressive, everything from order receipt acknoledgement through confirmation of delivery.



by:

etrailer did it again this company is great. great products at a good price.they make ordering and shipping easy. the instructional videos are a big help.

  • Recommended Wiring, Junction Box, And Breakaway Kit For 18-Ft Tandem Flat Bed Trailer
    To re-wire your 18-ft trailer you will need a few things. I recommend installing a junction box like part # PK52248. You can run your trailer connector like part # H20044 to the junction box and use the terminals in the box to run the wiring to the trailer. For 7-way jacketed wire I recommend part # DW04914-1. This is sold by the foot. The junction box will also make it easier to install and use a breakaway kit like part # HM20001. This kit includes a charger and a weather-resistant...

  • 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.

  • Can Trailer Brakes Lock Up if a Breakaway System has a Dead Battery
    No, if the breakaway battery on the trailer is dead and the pin is pulled out of the switch then no power would be sent to the trailer brakes and they would not lock up. If they do lock up then the brakes must be getting power from another source or the battery isn't dead. I recommend checking the wiring for shorts and corrosion and fix any pinched or damaged wires as needed. If you suspect the breakaway system is bad I recommend replacing it. One of the most popular systems we carry is...

  • Difference Between Hopkins Breakaway Battery Kits HM20001 and 20099
    The big difference between the Hopkins Engager breakaway kits is that the # HM20001 does not have a charge status display on the lid like the part # 20099 does. The # 20099 allows you to press a button and know what the charge of the battery is like.

  • Does Bright Way Trailer Breakaway Kit Come With Mounting Hardware
    The Bright Way Trailer Breakaway Kit with Switch, 12V, 5-Amp-Hour Battery, and Charger # 3802339 does not come with mounting hardware; you would need to supply your own self-tapping screws from a local hardware store. If you were looking for a breakaway kit that did come with mounting hardware, I recommend the Hopkins Trailer Breakaway Kit with Built-In Battery Charger - Side Load # HM20001. This comes with self-tapping screws as well as U-bolts so you could mount it to your jack post...

  • Breakaway Kit for Use With Electric Brakes
    For a breakaway kit with the use of Dexter 10" x 2-1/4" electric brakes such as # 23-26-27 (manual adjusting) or # 23-468-469 (self-adjusting) I recommend the Hopkins Trailer Breakaway Kit # HM20001. The reason I like this breakaway kit is because it has a built-in battery charger for convenience and because it is simple to mount the battery box, which you can do with either self-tapping screws or U-bolts, both of which come with the kit. I have added links to video installs of both...

  • Can Breakaway Pin be Pulled to Help Prevent Trailer From Being Stolen
    At first glance that is a great idea but if you want to keep a trailer from being stolen your best defense is installing a lock or multiple locks so that potential thieves see that your rig is more challenging than the next. You mentioned Blue Ox but the only thing they have with a breakaway kit is the Patriot # BLU37TR which installs in a towed vehicle that can be locked so I believe you are referring to a kit like the Hopkins # HM20001 which installs on a trailer. Either way, the stored...

  • What is Difference Between Breakaway Kit for Trailer that's Rated for Tandem Axles and Quad Axles
    The difference between a trailer breakaway system that can work on a trailer with up to 2 axles and one that can handle up to 4 axles is the battery the kit has and the amount of amp hours it can provide since the more brake assemblies there are the more amps it takes to activate them all. The part # 3802311 is a 10 amp hour setup that could work on 4 axles whereas the kit you referenced # HM20001 has a battery with only a 5 amp hour rating and that's why it's rated for use with tandem...

  • How Much Force does it Take to Pull the Pin on a Break-Away Kit Switch
    It is a simple switch, so brand compatibility should be a non-issue. When the pin is pulled, two pins are allowed to contact and complete the circuit to engage the brakes. Any switch should work fine. I pulled the Hopkins Switch, part # HM20010, to test it out. It does take a good tug to pull it out and close the switch. You should not need to use two hands, but it should not easily slide out. You do not want the pin coming out when you hit a hard bump. I would not repeatedly pull the...

Seven inch brake assemblies like # 23-48 that you selected work with the Trailer Hub & Drum Assembly, item # 8-257-5UC3, which will fit in wheels starting at 10 inches in diameter.

  • Can Trailer Be Towed if Battery in Breakaway Kit is Dead
    Your trailer's brakes will not lock up from the battery in a breakaway kit, like the Hopkins Brake Master # HM20001 being dead. If the breakaway battery is dead there won't be any power supplied from the system and it wouldn't have any impact on your brakes. Your breakaway battery should be tested before towing. If it's dead then it will not be able to do it's job of engaging your trailer's brakes in the event your trailer is separated from your tow vehicle.

  • Will a Breakaway Kit Damage the Brake Controller if Tested with the Trailer Connected
    I would disconnect the connector before testing so that you do not back feed power to the Prodigy controller. This is the best way to ensure there is no damage to the controller and to be sure the breakaway system is functioning properly. The breakaway is designed to work when the trailer has detached from the vehicle so the electrical connection would be severed. Most Brake controllers are protected from back feed so if you did test the breakaway with the trailer connected you should...

  • Does Trailer Breakaway Battery have to be Charged for Truck to Sense Trailer Connection
    The breakaway system battery is not related to whether or not your truck will sense a trailer connection. It actually will look for the slight amperage draw that brake magnets create to determine this. While I strongly recommend waiting to have your breakaway battery fully charged before towing your vehicle will see a connection whether it is or not.

  • Theft Prevention Recommendations for a 5th Wheel Trailer
    You could remove your breakaway switch pin while your trailer is in storage, however, a determined thief will get what they want in the end. If he went through the trouble to break in and attempt steal your trailer, it would not be a problem for him to simply cut the wires from the breakaway switch. Cutting the wires from the breakaway switch would be fast and easy. Another factor to consider is that the battery will only last for a short time and it will drain completely. Leaving the...

  • Troubleshooting 7-Way Replacing 6-Way Install Where Brake Output Stopped Working
    The is most likely related to the fact that there are two ways a 6-way will typically get wired and the only difference is that the 12 volt accessory circuit and the brake output circuit are switched. I attached a picture that shows a diagram for a 6-way for you to check out. Most likely something got mixed up when making the conversion due to the difference there so you'd need to check the wiring.

  • How To Move A Trailer With A Dead Breakaway Battery
    On most breakaway kits such as the Hopkins Brake Master part # HM20001, you will not need to cut or splice any of the wires to move the trailer with a dead battery. If your power supply is not active, then the only effect is that the breakaway system will not send power to your trailer's brakes in a breakaway situation thus allowing for free movement of the trailer. Even if the battery is dead, the brake controller will still allow you to activate your trailer's brakes To prevent further...

You can use a circuit tester like part # 3808 and test the wiring on the trailer to make sure you have all of the functions as the diagrams in the help article show. Typically, a 6-way connector has all of the functions of a 7-way but with no back-up light wire. For a 4-way to 6-way connector for your 1998 Toyota...

    You will want to use a standard 12 volt deep cycle trailer battery to operate the interior light. You will NOT want to use a trailer breakaway battery. The breakaway battery is not designed to power other trailer accessories or lighting, it is just designed to operate the breakaway system. The DOT regulations state that a trailer breakaway system needs a dedicated battery.

  • Can 12V Feed from Vehicle 7-Way Overcharge Trailer Battery
    You don't need to install any other parts in line with your 12V trailer battery line. Because the current being sent through the 7 pin power wire is so low, it acts more like a trickle charge to simply keep your battery topped off. It is not powerful enough to actually provide a full charge to your trailer battery, so it couldn't overcharge it even during a long trip. The Breakaway Kit Battery Charger # 20011 is used to prevent overcharging the smaller battery in a breakaway kit, like...

    You should not have any issues using the Hopkins Trailer Breakaway Kit with Built-In Battery Charger # HM20001 on your trailer hooked up to your 2019 Ford F-150. The built-in charger automatically refuels the battery when connected to the tow vehicle. Although we do not have any information or reports on an F-150 sensor for breakaway batteries, the draw from the charger would likely trigger the same on your vehicle.
