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.

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.

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:

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:

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:

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:

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:

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:

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:

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:

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

See what our Experts say about this Hopkins Trailer Breakaway Kit

  • Do I Need to Replace the Brakes On a Trailer After Driving with the Breakaway Pin Pulled
    In order to see what damage was done while driving with the breakaway pin pulled, you will need to remove the hub/drum and inspect the shoe lining as well as any other mechanical components. If you indeed drove a few miles with the pin pulled then most likely you will need to replace the braking assemblies because of the pad wear. For this, the Electric Trailer Brake Kit part # AKEBRK-35-SA for 3,500 lb axles or the Electric Trailer Brake Kit part # AKEBRK-7-SA for 5,200 - 7,000 lb axles...

  • 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...

  • 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...

  • Converting From Surge to Electric Brakes on a Boat Trailer with 5,200 Lb Axle
    It sounds like you are trying to replace the surge brakes you have on your trailer now with a set of electric brakes. If that is the case then you will not have any issues with submerging the electric braking assemblies in water. The majority of newer boat trailers even come with electric braking assemblies from the factory. However, you will need to unplug the trailer connector before launching the boat. There won't be any issues with your factory trailer brake controller in regards to...

  • 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.

  • Switching From Surge to Electric Brakes on 1996 U-Haul Trailer
    Assuming you're right about the current drum size you will need 10" brake assemblies, not 12". You can use the Electric Trailer Brake Kit # AKEBRK-35-SA. These fit a 4-bolt brake flange pattern and are typically found on 3,500 lb axles. I recommend verifying this with what you have to be sure. You will also need to add the # H20046 for wiring and the # HM20001 for a breakaway. You can lock out your surge coupler to avoid replacing it. If you don't have a 7-way on your 2000 Chevy Express...

  • Parts Needed To Add Electric Brakes On Motorcycle Trailer
    When adding brakes to a trailer the first thing you will need is a brake mounting flange on the axle. If you do not have a brake flange I recommend part # 4-35. This should be welded in place by a professional welder because it needs to be square and concentric. The brakes I recommend for you are part # AKEBRK-35L-SA. These are self-adjusting 10 x 2-1/4 inch brakes and will work with 13, 14, and 15 inch diameter wheels. This is the brake for the left hand(driver side). For a brake that...

  • Should the Cable on Hopkins Break-Away Kit # HM20001 Engage Trailer Brakes If Safety Chains Break
    The breakaway cable on the Hopkins Break-Away Kit, part # HM20001, should engage the trailer brakes if the trailer becomes disconnected from the tow vehicle and the safety chains fail. So you will want the breakaway kit to be the last line of defense against a runaway trailer. As far as length of the breakaway cable, that will be determined by where the breakaway kit will be installed on the trailer. I am including a link to a FAQ page on breakaway kit installation and a link to a video...

  • Trailer Brake Magnets not Not Working on Snowmobile Trailer Towed by a Chevy 2500 HD Silverado
    I think you are going in the right direction. I would start with the ground connections since that is the easiest fix for this type of situation. If the grounds are not making good connections, you are going to have issues. Applying power directly from a 12 volt battery is very different than applying power from a brake controller mounted on the truck and going through two trailer connectors. Make sure the brake magnet wires are attached to a clean, rust and corrosion free part of the trailer...

  • Parts Needed To Convert From Hydraulic to Electric Brakes on a Boat Trailer
    I recommend switching from hydraulic brakes to electric brakes as this will be far more cost effective and easier to install than an electric over hydraulic setup. In order to covert all you will need is a new set of electric braking assemblies, a 7-way trailer wiring harness, and a breakaway system. The electric braking assemblies will need to be choose accordingly based on your brake flange, axle capacity, and hub dimensions. The axle capacity is usually the easiest to find and will...

  • 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.

  • 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...

  • 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.

  • Parts Needed To Convert From Surge Brakes To Electric Brakes on 2003 Centurion Boat Trailer
    The # HBA-10 can withstand the elements but it is not designed to be submerged. Something like rain is fine but if you submerge it on your boat trailer you risk damaging the actuator. If you want to switch to electric brakes you will need need to start with hub and drum assemblies (if you don't already have them) and electric brake assemblies. The hub/drum and the brake assemblies will depend on your axle. For example, if you have a 3,500 lb axle you can use the # AKHD-545-35-G-K or #...

  • Can a Breakaway System and Brake Controller be Installed at Same Time on 2002 Dodge Grand Caravan
    You can have both a brake controller and a breakaway system since they serve 2 different functions. A brake controller, which may be required by law in your area (check local and state laws) will apply the trailer brakes when you apply the tow vehicle brakes. A breakaway system only applies the brakes should the trailer become uncoupled from the tow vehicle. In many states a breakaway system is also required by law. The breakaway system needs to be able to apply the trailer brakes on full...

  • What is the Function for the 3 Wires Coming out of the Charger
    The 3 wire component is the charger and receives 12V power from the vehicle connector and charges the breakaway battery. Now the blue wire coming off the charger will go out to the breakaway switch. I included a video on a similar charger # 20011 for you to look at. It will have the same functions as your charger.

  • 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...

  • 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...

  • How to Reset the Hopkins Trailer Break-Away Kit with Charger # HM20001
    You are correct. The system does not have to be reset electrically to allow for normal trailer operation. Instead, like you said, the pin, or what separates the contacts, needs to be put back into place. What happens is, if the trailer detaches from the tow vehicle, the mechanism separating the pins is pulled out. This allows the contacts to touch which in turn engages the break away system to stop the trailer.

  • 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...

  • Parts Needed To Convert Hydraulic Brakes To Electric Over Hydraulic Brakes Towed By 2019 Ram 3500
    Dan, it is possible to convert your trailer's hydraulic disc brakes to electric over hydraulic brakes easily. The conversion requires an electric over hydraulic actuator, break away kit and a brake controller. An electric over hydraulic system gives you the stopping power of hydraulic with the quick response time of electric brakes. Since you already have the hydraulic braking assemblies replacing the brakes is not needed. For an electric over hydraulic actuator I recommend HydraStar Electric...

  • 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.
