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:

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:

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:

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 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

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

  • Recommended Break-Away Kit for the Roadmaster 2000-1 Tow Dolly
    The Roadmaster Tow Dolly # RM-2050-1 does not come equipped with a breakaway system but you can certainly add one. I recommend the Hopkins # HM20001, because of how easily it installs. I have linked an installation video of the Hopkins Break-Away being installed on a trailer for your convenience.

  • 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.

  • 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...

  • How to Add Electric Drum Brakes to a 2017 Covered Wagon 6x12 Single Axle Enclosed Trailer
    I would love to help you add electric drum brakes to your 2017 Covered Wagon 6x12 Single Axle Enclosed Trailer. In order to make sure you get the correct parts, I would need to know the serial number on your axle. In order to obtain this you would need to crawl underneath and look for a white tag on the center of the axle and locate usually a "SN #". Once you can provide this to me I would then be able to verify all the parts you need. I also recommend taking a look at the help article...

  • Can the Trailer Breakaway Battery be Used to Power a 12 Volt Interior Light
    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. To keep the trailer battery charged you will need to run a 10 gauge power wire like the, part # 10-1-1, from the 12...

  • 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...

  • 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...

  • Troubleshooting Trailer Brakes That Stop Working When It Rains
    I'll start this off by saying that I don't think the issue has anything to do with the breakaway switch or junction box, It sounds to me like the rain is causing a short on your wiring and this is what is causing your brakes to go out; since you just had new leaf springs put on the 5th wheel trailer it's possible that something was damaged during the repair process. I would first examine the ground wire connection on your trailer-just because that's an extremely common cause of shorts...

  • 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...

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.

  • Troubleshooting Lighting on Snowmobile Trailer that Doesn't Work
    You have the issue isolated to being on the trailer somewhere. What you will need to do is first check that the trailer connector is clean and free of any corrosion as that's the easiest thing to check. Next you will want to check the conditions of the ground wire from that connector to the frame of the trailer. Since all of the lights aren't working it makes me think the main ground that feeds all the lights isn't sufficient. Aside from that it could be a wiring issue to the assemblies...

  • 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.

  • 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...

  • 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...

  • 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...

  • Parts Needed to Add Electric Drum Brakes to Trailers with 2,000 lb Axles with 5 on 4-1/2 Wheels
    To add electric drum brakes to your trailers the first thing you will need are brake mounting flanges. There are different ones for different diameter axles. Given the lower capacity of the trailers I am guessing the diameter of the axles is 1-3/4 inches at most. That is the smallest brake flange there is, # 4-34, for 2K axles. Anything smaller or that isn't common will require a flange to be fabricated. A note on welding them on: generally it takes a special jig and someone with experience...

    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...

    The Roadmaster Tow Dolly part # RM-2050-1 would be a great dolly to use to tow your 2018 Toyota RAV4. Your wheel size would not be an issue either. This comes with wheel nets that will fit well and brakes so you'd be set. The Roadmaster Tow Dolly # RM-2050-1 does not come equipped with a breakaway system but you can certainly add one. I recommend the Hopkins # HM20001, because of how easily it installs. They aren't a requirement but it would be a great idea.

    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.
