Good solid brake shoes, fit on perfectly, in fact the first problem free repair job I have tackled in months. The camper is as unusual as the photo is of Alabama weather.

I have only put about 3,000 miles on it since then, if it brakes before I but 25,000 miles on it I would be unhappy with it. For this, a year is simply not enough
James - 10/11/2021


Perfect replacement if you are experiencing fatigue failures on your brake hardware. Easy installation. 7000 miles since installing and no issues.


The brake assemblies were in relatively good condition when received except for the actuator wires into the backer plate. The insulation on these were damaged presumably by a tool when inserted the associated strain relief. I repaired this with some RTV. Also, this was my first e-brake job and I was not impressed with Dexter customer support - non-existent.


Excellent service, fast shipping, good prices and quality products (Dexter).
Really happy with etrailer.


E-trailer is a great company to deal with. The electric brake assemblies were exactly the same are the original which insured installation was smooth and easy. Support after the sale is unsurpassed. They follow-up after the sale with instructional video clips to insure there are no "hiccups". After installation of the new brakes, I road tested and calibrated the controller (a device that I previously purchased from E-trailer). E-trailer was referred to me by a friend. I will definitely use them again and will not hesitate to refer them to others. Lastly the assemblies are American made and the shipping was free, could not improve on service, product or value. Thanks


Ordered the parts by phone. Melissa was highly knowledgeable and extremely professional. Would recommend eTrailer to anyone that needs trailer parts or trailer hitches.


Great selection of parts, fair prices and fast shipping. Would definitely recommend to everyone.


Etrailer is a great company to deal with. Great helpful videos. Parts ship fast and free. These brake assemblies are fast and easy to install


Complete and easy to install


The construction of the brake assembly makes it simple to install. Also the product info video describes the specifications.


Excellent fit and finish, as usual from Dexter. Installed on a Lippert 3500# axle with no problems.


very happy with service and product


brakes worked fine last summer, complete assemblies were a better deal than just replacing the shoes. my son in law and myself just combined an order this weekend (save shipping cost) on trailer tow mirrors from etrailer for our vehicles.

just came back from OBX 1400 miles-trailer brakes worked perfect.
glenn b - 04/17/2017


great prices & service


Good quality product, zero issues after one year. Works as intended.


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.

Still working just fine.
Jeff K - 12/22/2017


It is always a pleasure ordering from etrailer. Never have any problems with my orders. They have quality products, and tons of information and videos "by people who know what they are talking about" on their website. Great company to do business with.


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.


I installed these brakes as part of an upgrade and rebuild of a 20 year old trailer and so far they are working great!


Having some mechanical skills, replacing my trailer brakes was an easy job. I also did the wheel bearings and races, which was a new job for me, without any complications. The eTrailer parts, tools and videos made this job go smoothly. Buying the brake assemblies on the backing plate is the way to keep the job easily manageable.


First off, Etrailer is awesome. I ordered two pairs of loaded plates and hubs on Sunday night and they were on my door step by Wednesday!..
Three issues with the plates.
1. On one plate, the two wires from the magnet were about cut in two on the back side of the plate right as they come out of the plastic retainer. Must be getting pinched somehow in shipping.
2. Both left plates had lubriplate grease where the brake pads rub the backing plate and at all pivot points. Neither of the right side ones did, requiring disassembly of the new plates to grease the spots that should have been. (Somebody had a bad day on the assembly line!).
3. Product information led me to believe that new backing plate nuts would be included. They were not, but new lug nuts were included with the wheel bearing kits.

Only thing that I would suggest to Etrailer would be to carry replacement lock tabs for the bearings. Other than that, a couple of hours and brand new brakes & hubs all around. They are working great!
Thanks Etrailer for the great products, prices & shipping!



I bought these to add brakes to my utility trailer. erailer customer service was excellent.
They were able to price match a competitors price and the shipping was fast.
The brakes fit well and the install was easy.
Why only 4 stars then? Its a small thing but the brakes came with 4 nuts for the install but did not included the required lock washers. No problem I thought, so off to the local box store to get 7/16 washers. This proved futile, and It took me quite a while to finely locate the correct washers.


The parts I ordered were perfect fit and easy to install They made my trailer safe and functional again


Great service and fast shipping. The installation is not technically complex but takes some effort and time, especially on an old trailer. The installation videos provided by etrailer were very helpful. Don't forget the BP10-220 Adjuster Plugs and W80630 Brake Adjustment Spoon. You can find the nuts, washers, and waterproof electrical butt connectors at your local hardware store if needed. Also make sure you have what you need to regrease the bearings as you do the install.


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.

  • Which Left Hand Brake Replaces A 10 Inch 3,500 Pound Dexter Brake Assembly?
    If you only need a left hand brake, we definitely have what you need. The Dexter Electric Trailer Brake Assembly # 23-26 will be just the left side (driver side) brake that will come with the # 23-26-27 Dexter 10 inch 3,500 pound brake kit. This will also include the mounting hardware so no other parts will be needed.

  • How to Pick Out Brake Assemblies for Terry Resort Fleetwood 5th Wheel Trailer
    Picking out brake assemblies for trailer axles is actually pretty easy but I am not able to determine the info I need from your trailer info since it's not something manufacturers keep records of. You do need to order a total quantity of 4 assemblies since To pick out the correct brake assemblies for your trailer you need to know a few things. You will want to measure the inner diameter of your hub/drums and the depth of the drums to determine what brake assembly dimensions you need....

  • Do Hubs Go In Front or Behind Axle Tube When Installing Torsion Axle?
    It sounds like you're trying to mount a torsion axle, so you'll want to mount the hub center behind the axle tube in order to correctly orient the axle. Your spindles won't be exactly 90 degrees from the hub face since the axles will flex a bit in the middle; once the axle is placed on the trailer, the weight of the trailer and load will correct this and allow your tires to run flat on the ground without worrying about abnormal wear.

    In order to pick out the correct hub assembly for a trailer you are going to need know a few key pieces of information. The first thing you will need to know is the bolt pattern of your hubs. This is so you get a hub that is compatible with your wheels. Next thing you will need to know is what spindle you have on your trailer. In order to do that you can either get the inner and outer bearing numbers from a hub or use a dial or digital caliper to get exact measurements of the spindle....

  • Should Grease Seal be Flush with Hub
    It sounds like you are referring to the grease seal for your new hubs. When installing a seal at the back of a hub the outer part of the seal should be flush with the hub. I have also attached a short video demonstration that you might find helpful. Then when adjusting the new brake assemblies like the Dexter # 23-26 that you referenced, you will only want a slight but constant drag of the shoes on the drum when the wheel is turned after being properly adjusted. I have again attached a...

  • Do Trailer Hubs and Drums and Brake Assemblies have a Left and Right
    Usually hub and drum assemblies themselves don't have a right and a left; they can be used on either side. If your neighbor has hubs that indicate that one is a left and the other is the right then they should be installed in that orientation for the best performance. Brake assemblies do have a left and right though. If you were to switch sides with brake assemblies the braking would not be as strong but depending on the weight of the trailer you may not notice much of a difference. Regardless...

  • How Do Dexter Trailer Brake Drums Compare to Other Brands
    I wasn't able to find anything in regards to a brand of trailer brake assemblies by the name of Shoals but Dexter on the other hand is basically the industry leader in terms of trailer brakes/hubs etc. so if you are considering the Dexter brand you'll be very happy with them. I attached a link to a page that has all of the Dexter hub/drums we offer as well. If you can get back to me with the axle capacity you have and your bolt pattern I can get you the correct replacement you'd need.

  • Trouble Shooting Trailer Brakes that are Locking Up
    I would start by adjusting the brakes. Even brand new self-adjust brakes need to be adjusted. I would think on a brand new trailer this would already be done but you never know. Take a look at the video I attached and skip ahead to around the 4:30 minute mark to see the brakes being adjusted. You also may just need to turn down the gain on your electric brake controller.

  • Using Trailer Brake Assembly on Opposite Side of Trailer
    The brake assemblies are specific to the correct side of the trailer, a right hand brake assembly could not be used on the left side of the trailer. The assembly should be mounted so the magnet is at the bottom and the larger of the two brake pads is pointing to the rear of the trailer. I've heard of folks mounting the assembly upside down on the opposite side of the trailer, but the brake assembly will never work correctly if installed that way.

  • Troubleshooting Trailer Brakes that Lock Up After Brakes are Applied for 10 Seconds
    When I first read your question I immediately thought that your brake controller must be setup wrong and that setting it up properly would fix your problem. It sounds like you have the gain set to high and the ramp up speed set too low on a time-delayed controller. What you will need to do is find a flat parking lot while connected to your trailer and travel about 25 miles per hour and then fully apply the manual override of your brake controller, if the brakes lock up lower the gain setting...

  • Trailer Brakes Will Not Lock Up Even with Full Battery Power
    You may need to adjust the trailer brakes. Trailer brakes will need an initial adjustment so they are set properly. You need to be able to hear a slight but constant drag of the pads on the drum when the wheel is turned. I have linked a video to the right that should help. Go to about the 4 minute mark to see our installer adjusting the brakes.

  • Troubleshooting Brake Actuating Arm Breaking on a Trailer Brake Assembly
    First thing I would do is pull off the hub and inspect the inside surface where the brake magnet rides. If it isn't completely smooth it could be grabbing the magnet and breaking it. Most likely you would have needed to replace the hub after the first time the magnet broke. Are you sure you are using the correct orientated assembly? Brake assemblies are sold in right hand and left hand versions. The actuating arm of the assembly should be pointing towards the front of the trailer. In...

  • Troubleshooting Trailer Brakes that Surge at Slow Speeds with a Tekonsha Brake Controller

I would verify that you have it set up properly and that the controller is leveled properly and pointing the right direction. The Tekonsha controllers all have different level ranges that they can function on, but basically you want to make sure the controller is totally parallel with the direction of travel, is level from side to side and as close to level from front...

  • Incorrectly Installed Brake Assemblies on Dual Axle Camper

Is it possible that the axle was removed at one time and reinstalled incorrectly? If you look at the photo I provided, you can see how the components of the brake assembly should be situated. The magnet should be at the bottom of the assembly, and the actuating arm for the brake shoes should be at the front (closest to front of trailer) of the brake...

    First, disconnect the trailer from the truck. Then get a separate 12 volt battery and apply power directly to the brake output wire on the trailer side. The brakes should lock up. If they do not then at least we know the issue is on the trailer. If the brakes are properly adjusted (there should be a slight but constant drag of the pad on the drum when the wheel turns) then check the inside of the hub and the brake pads for any grease that may have somehow gotten in the drum or pads.

    If one of your tandem-axle trailer's four electric brake assemblies is dragging, but the three other brakes are functioning properly, you can check the malfunctioning unit for proper adjustment if it is an adjustable type. If it is not an adjustable brake assembly you can still inspect it to ensure there is no obvious physical damage to any of the mechanical components (pads, linkages, springs or magnet) that could be causing it to drag. You can also use a multimeter to test it for proper...

  • Testing Brake Magnets to Determine if They Need to be Replaced
    It sounds like your magnets are in need of being replaced. Since the normal spec for 10 and 12 inch brake magnets is 3.2-4.0 Max amps at 12-13 volts and 7 inch magnets is 3.0-3.2 max amps at 12-13 volts and yours is coming in much lower than that it would indicate that the leads are bad and the magnets should be replaced.

  • Troubleshooting Weak Trailer Brakes that are Adjusted Properly with New Assemblies
    It sounds to me like one of two problems. The first would be that your ground is indeed not strong enough to allow enough amperage to be applied to the trailer brake magnets. In this case I would make sure that the ground wire attached to the trailer at the trailer tongue is secured to a suitable clean surface. It could be that the main ground wire of your trailer is no longer making solid contact from corrosion or it has come loose in some way. Check out the help article I attached. I...
