A year later still working as should would highly recommend


Parts arrived two days early, were packaged very nicely and as ordered.


High quality, perfect fit, easy installation, I highly recommend these.


This is a Dexter OEM brake assembly, so it was manufactured per Dexter spec's and quality control.


Great service. When your salesforce KNOWS product and application both sides WIN.


I removed and reconditioned the axles on my snowmobile trailer. Salt corrosion damaged the brake assemblies. The replacements assemblies from bolted right on and made short work of the brake repair.

Jeff K.


Still working just fine.


We bought bearings,seals,brakes and brake drums for our horse trailer as we travel around with are furry pet.We give a A+ for quality,service and price .will use trailer for all are future needs. Thank you

Jim M.


Just great.We bought wheel bearings,Brake shoes and drum.I just repacked the wheel bearings and everything looks new.Your great company and a good price 2 thumbs up and 2 happy horses.


Fast, Friendly, Knowledgeable service.


I bought a new car trailer with brakes on only 1 axle. etrailer had the exact same brakes for me to put on the second axle. These drum brakes were really easy to install, wire and adjust / re-adjust. I'd really recommend brakes on both axles if like me you're towing close to 7000lb. I've made a couple emergency stops around town, and didn't have the feeling i was being pushed by the trailer at all.
I'd also really recommend getting a high tech brake controller if you're buying one. I had a cheap one that really sucked, i had to constantly readjust brake power every time my speed varied (to stop being pushed by the trailer at speed or jerking to a stop at low speed). Annoying and dangerous IMO.


Used these electric brake assemblies to replace the hydraulic units which became useless due to the master cylinder in the coupler becoming rusted and frozen up. Everything about the units was top notch and they bolted directly in place of the hydraulic backing plates. Shipping was fast with detailed follow up provided by Etrailer (probably the best of any internet company I've dealt with.)

Packaging was more than enough with more packing material and staples than was really required. ( 15 staples in the box ends alone where 5 would have been more than enough) Unfortunately, the assemblies were "nested" back to front into one another which caused the brake shoe of one unit to cut off the wire leads of the other. "Back to back" or "front to front" would have solved this issue which has happened to other customers. Additionally, the one plate had dust plugs for the brake adjuster provided while the other one had none. Both of these problems were minor but kept the experience from being totally outstanding.


I ordered a complete brake kit for my 6x10 wells cargo trailer (backing plates wiring, hub assemblies, junction box). The items were not packed well and the brake wire got shredded by the hub assemblies during shipping. A quick call to eTrailer and a replacement cable was sent out right away - great customer service! Installation of this kit was a breeze thanks to the instructional videos available on the eTrailer website. All the items are of excellent quality and everything fit together perfectly. One small wish would be to include the lock washers and nuts (4 per side) that are required to mount the backing plate instead of having to order it a la carte.


Came as described, packaged i a “ bulletproof” package & parts went on without a hassle. Delivery was quick. Only company to trust in trailer maintenence



Perfectly functioning, dead reliable product


I completely rebuilt my trailer. The brake assemblies ordered were easy to install. It was much easier than trying to rebuild my existing brakes. The instructional videos from made the installation of the breakaway kit a breeze. Shipping was upgraded for free and received my order very quickly. It was a pleasure doing business with


Added brakes to my 6X10 Wells Cargo enclosed trailer. They are working great. Easy install. As always, new trailer brakes take some time to wear in before you get full "lock - up" level braking. I'd buy these again. As always, great order and order fulfillment experience with etrailer.


A year ago I ordered 4 trailer brake assembly sets, brake drums and bearings. They arrived quickly and in good condition. Everything fit well and I had no problems when I towed my trailer across the country. I would definitely buy from Etrailer again.


Still got to put them on, but they look good, I forgot to order the brake controller so I missed out on the free shipping,.
Can you make a recommendation for a controller, I have a 2004 Chevy Sub 1500. Nothing fancy

One of my favorite controllers is the Prodigy P2, part 90885. It has all the important features for a proportional controller, without extra bells and whistles that may be nice but not necessary. A relative new-comer to us, that has been received well so far is the Redarc Tow-Pro Elite Brake Controller -, part # RED44FR-3015-S. It gives you a knob to install in your vehicles panel which takes up far less room then the brake controllers of the past.


10" Electric Trailer Brake Assembly - 23-27 is quick and easy to install. saves hours of frustration trying to assemble brake lining and springs. I recommend to buy the brake drum that goes with the brake assembly also. No power tools needed for this job. View the provided on line instruction and viewing the video was very helpful installing this product. Thank ETrailer


About a year ago I replaced all my existing breaks on my camper with these. Swapping them out was painless (first time doing so.) After getting the adjustment correct on the brakes and the brake controller they’ve worked great! We have a lot of hills where we live and camp almost every weekend May-October and have had no issues. I will double check in the spring but as of when we parked for the winter there was no need for adjustment yet, plenty of pad left for another season or two!


OEM Made in USA and Dexter original. Exact fit. This is the best way to service brake systems especially on tandem axle applications. Great price, great service. Best with new nuts and lock washers and new Dexter drums and did I mention made in USA.


I am refurbishing a vintage trailer and the previous owner had disconnected the brakes, not sure why. To be safe I decided to go brand new. These brake assemblies arrived in the factory package in good condition. They were easy to install and are working fine. As always the folks at are great to work with and always check up to insure that all is well and address any concerns. Thanks


Product was as advertised. Form, fit and function were excellant. Assembly was a breeze, especially with the non-polarity of the wires. Just bolt them on, plug them in, adjust them, and go. Recommend buyers also purchase the 4 nuts that hold each backing plate onto the trailer's mounting flange. They do not come with the assemblies, and 7/16 x 20 (fine thread) nuts are getting difficult to come by. I went to my local Lowes to purchase 16 nuts and lock washers for the 4 assemblies I purchased.. They only had 17 nuts in the entire store.


Fit just like described.


Purchase from etrailer was simple and easy. The product was shipped quickly and the package arrived in fine shape. One of the brake assemblies must have been bumped around pretty good as the adjuster and spring were laying on the packing. A couple of minutes to reassemble the parts and all was good. The product fit as advertised with no problems. Adjustment was simple (follow youtube videos if you've never done this type of work before) and I'm only waiting for a test run in daylight.

As for what I liked about the product, they're made in USA and appear to be of superior quality over the OEM Chinese products they replaced. I try to purchase USA-made products when possible and etrailer made the choice simple by listing where this item was manufactured. I also like how etrailer followed up with emails offering help if needed. While I didn't need help, it was a nice touch and I will purchase from etrailer in the future.


Haven't been able to try them out yet, but they installed pretty easily, even for having never dealt with trailer brakes before. The only complaints I have are that the hardware and adjuster hole plugs were not included. Seriously, can't we add a buck on the price and throw them in?


Purchased the entire brake and hub assemblies for about the same price as a brake job at the trailer shop. Shipped quickly...etrailer even upgraded my shipping at N/C.

The brake assembly and hubs were simple to install. The brake controller took less than a minute to install.

Good prices, great service. Would definitely do business with etrailer again.

  • Troubleshooting Weak Trailer Brakes After Converting from Hydraulic to Electric Drum Brakes
    There are several possible reasons why you have weak trailer brakes. Make sure the trailer is disconnected before testing the brakes. First, I recommend changing where the ground is located to a place closer to the brake assemblies. Make sure it is grounded to a clean and corrosion free location. Next, visually inspect the brakes for any grease or oil on the magnets and brake linings. Since the assemblies are new, it is unlikely that the magnets are bad or the drums have accrued grooves....

  • Proper Adjustment of 10 Inch Electric Brakes On Trailer
    To adjust your brakes, you will want use a brake adjustment tool and turn the adjustment gear which is accessible through the back of the brake assembly. You will want to tighten the gear so that you cannot turn the wheel, then you will want to back the gear off 10 clicks. This will be the proper adjustment for the brakes and will need to be repeated on each brake assembly of the trailer (see video link). Another adjustment you will want to make is with your brake controller. If your brake...

  • Selecting Trailer Wheels, Tires and Brakes for Off-Road Teardrop Trailer
    Vehicle wheels can have different offset than trailer wheels. Offset is any difference between a wheel's center line and the mounting surface. Positive offset moves the tire closer to the trailer frame and negative offset moves it away. This is why only special trailer wheels are recommended for use on a trailer. Similarly, only special trailer (ST) tires are recommended for use on trailers; passenger vehicle tires should not be used on a trailer, or vice versa. I linked for you our main...

  • Trailer Brakes Not Performing Well After Installing New Brake Assemblies and Drums
    The fact that a trailer brake won't lock doesn't necessarily indicate a problem. For best braking, you do not want the brakes to lock up. A skidding tire doesn't provide optimal braking. However, if you can get things adjusted so that the brakes apply to a degree just short of lock up, you'll have the most effective braking possible. Since you have new hubs and brake assemblies, you shouldn't need to sand anything. Since the magnets are getting 12 volts, the most likely cause of what...

  • Do Electric Trailer Brakes Work in Reverse
    Electric trailer brakes will work slightly in reverse but due to how the mechanism works they don't grab as hard in that direction. That's just the nature of the design. Sounds like yours are set up properly though. Good news is that you won't be travelling that quickly in reverse so the need for powerful trailer brakes in that direction isn't nearly as important as forward.

  • Are Electric Brake Assemblies Compatible with Boat Trailers?
    Yes. Electric brake assemblies like the Dexter 10 inch # 23-27 you referenced can be added to a boat trailer that will be submerged. Some boat trailer manufacturers are even getting on board with the electric brake idea due to cost and function. You will want to note the trailer connector does need to be disconnected before your trailer wheels hit water as electricity and water do not interact well. This will protect your vehicle and trailer from electrical surge issues. Then you simply...

  • Trailer Brake Controller Either Locks Up Trailer Brakes or Doesnt Brake Enough
    It is possible that the brake controller is mounted outside of the range specified in its manual and that could cause some unwanted behavior. If it is a time delay controller then you may need to adjust both the gain (power output) and the sync (how long it takes to ramp up to the preset gain level). You can also check to make sure both the trailer side and vehicle side connectors are clean and free of corrosion both on the pins as well as inside where the wires attach. I have included...

  • Why are Electric Brakes Getting Hot on 98 Coleman Camper After Installation of New Brake Assemblies
    It sounds to me as if there is one of three problems going on. The most likely problem is that the brake assembly on the right side is not properly adjusted. There is an access hole in the backing plate to insert a brake adjusting tool through and turn the adjuster in or out to properly adjust the trailer brakes. We have a video on trailer brake installation and at 4 minutes 40 seconds trailer brake adjustment is shown. Tighten up the brakes inside the drum until it stops turning. Then...

  • Can Trailer Brakes be Added Torsion Axle
    Hey John, it is definitely possible to add brakes to a trailer with torsion axles but it comes down to whether or not the spindles of the trailer axles have brake mounting flanges currently as the biggest hurdle. They can be added but it's a little more involved. Next you'd need to know the axle capacity and the wheel bolt pattern and from there you'd have all info needed to add brakes. If you check out the help article I attached you can see a guide that will walk you through the entire...

  • Brakes on 2011 Komfort Resort Tandem Axle Trailer Not Engaging Properly
    I would begin by inspecting the magnets on the trailer brakes. If the magnets have windings or wear marks, the magnets are bad and will need to be replaced. You would need to match up your brake assembly size for the correct replacement magnet. The next thing you will want to check is the wiring to the brake assembly and the magnets. Make sure that the brake assembly has a good connection and that there are no cut or frayed wires. You will want to make sure the magnets are connected to...

  • Can 10 x 2-1/4 Inch Electric Trailer Brakes be Used in Place of 10 x 1-1/2 Inch Brakes
    You will need to measure the width of the inside of the drum where the pad makes contact with the drum to determine if you can go to the wider 10 x 2-1/4 inch assemblies. If you cannot then you would also need to change out the hub and drum. To do that I would need to know the inner and outer bearing numbers stamped into the metal of the bearings. If the hub is wide enough then you can use the 10 x 2-1/4 inch assemblies # 23-27 for the right side and # 23-26 for the left. It is also...

  • What Would Cause Trailer Brakes To Be Jerky On a 2011 Keystone Outback 295RE?
    It sounds like the issue may be with your brakes on your 2011 Keystone Outback 295-RE. With the brakes jerking it is most likely an issue with a drum or multiple drums being out of round. This can sometimes be caused by the brakes overheating. You can have your brakes inspected at a trailer service shop where them may be able to also turn the drums to get them back to within spec. Otherwise you will most likely need to replace your brakes. If you can provide me with the axle information...

  • Troubleshooting a Dragging Electric Brake on a Trailer
    It sounds like there is an electrical short on your trailer wiring that is activating your left rear brake assembly and that is why the brake continues to drag and get hot. Since you have swapped the brake assembly out and still had the problem you know the problem is not in the assembly but somewhere else on the trailer wiring. I would start at the wiring near the brake assembly and check for corrosion and loose or exposed wires and fix as necessary. You will want to trace this back up...

A lot of times trailer brakes ground to the frame. I would just run all of the grounds back to the main ground harness of the trailer to see if that fixes the problem. The other problem is that it could be that your brake magnets are...

    Yes, electric brake assemblies will work in reverse. The brake controller in your tow vehicle would still activate in reverse as long as the brakes are applied. The actuating arm of the Dexter assemblies part # 23-27 will apply the brakes when pushed in either direction. That means that in forward or reverse the assemblies will still apply trailer brakes.
