Very nice product but installation instructions could have been more complete

by: Mike 02/19/2025

Needed all 4 brakes for my 30 foot Airstream.
One arrived looking still new, but with minor scratches on the inside face of the brake and the lube worn off compared to the others. The plastic clip that holds the brake wire on the back was also broken off.
It could have happened in shipping, as that one box was a bit beat up, and the 5 fasteners that hold it to the frame were in a bag, but floating freely in the box.
etrailer offered to replace the whole brake assembly, which I appreciated, but did not feel necessary.
They sent the replacement clip and it snapped in as expected adn all is good.
I will buy again when time to replace!

I'm glad we could help turn this experience around for you Mike, and we appreciate the opportunity to make this right for you! I'd loved to see a photo of your Airstream if you'd like to share one!

by: Ken 06/12/2026

I was hoping 10 years of technology would improve with the new back plate and shoe assembly, but it’s identical. Mostly, manual adjustment can’t be done with automotive brake tools as the two holes for adjusting do not line with the star adjuster.(misses it by 1/2 inch). The instructions don’t say to adjust manually after new install, but it’s the way I do it, otherwise it takes forever to auto adjust. Ken.

by: Gene 07/12/2015

Replaced old non-self-adjusting trailer brake assemblies with new self-adjusting ones. See photos of old & new. TIP: Temporarily tape new wires out of the way to avoid pinching them between the axle flange and backing plate when mounting the new brake assemblies (ask me how I know).

Brakes are still working great

by: J.D. 02/10/2017 One Year Later

These went on very easy, and worked great right out of the box. It was nice to have them all match. I spliced them in a couple days before going on a 1,000+ mile vacation to Arizona. They've worked flawlessly (I check them to make sure they aren't hung up). This was just one headache eliminated for the trip by just getting new brakes instead of messing around with junky old ones. We've had the toyhauler out on several other trips also. I will purchase again if I need any for another trailer.

The brakes have been working great. After the initial installment and adjustment, I havent had to do any additional work to any of them. They are performing great, really better than I expected. I always test them with my brake controller when I first get back on the road and they have always worked. I have recd a few of my friends to buy any parts they need from your website as it was easy and had lots of options trailer stores around here are pretty limited.

by: Ray Airstream 08/28/2019 One Year Later

Excellent Service. Quick shipping. Correct brake assemblies.

My brake sets did not have the plastic adjusting plugs included. I had to purchase them separately at nearly $1 each. It appears they are now included.

Would I order from etrailer again. You bet your aluminum trailer, I will!

I bought these brakes to replace the hydraulic brakes on my newly purchased (at DOD auction) M1102 trailer. The OEM eq was almost new (2010 model) but I wanted to remove the hydraulic surge brakes for electric. They are a perfect fit and easy to install. Would have been nice to have the dust covers for the back of the housing.

Exact Fit. We travel extensively in our Airstream. We purchased these as spares and they stay in our tow vehicle. We always inspect all of the rotating assemblies but stuff happens. We have heard of too many stories of breakdowns where people get stranded for days/weeks waiting for parts. Hopefully it doesn't happen to us, but we would be back on the road in a couple of hours.

I ordered a new electric brake assembly #23-458 and 12" drum kit #K08-201-98 for a 5200lb Dexter E-Z lube axle. All parts arrived on time and were correct. Ordering through Etrailer was fairly easy once I learned to navigate their site because there are a few variations to the parts I specifically needed for my axle. It helps if you have part numbers for your axle to compare with the ones on their site. I would liked to have had a place to enter my axle type, number, etc. and just have all the parts available for it displayed. Or perhaps an online chat page with a sales rep would be great too. All and all, I highly recommend and will definitely use Etrailer in the future.

Update: After a year and over 3500mi, my brakes appear to be working properly. With that said, I haven’t pulled my drums off for a thorough inspection. But so far so good.

Item: 23-458: This item Is a replacement for my 5th wheel camper. Do to the fact while traveling the brake did not release and failed on interstate I-40 late in the evening.The heat caused all the parts on the spindle to fail. The cost of replacing brakes, drum, bearing, seals, grease, plus service cost is Very Expensive after hours. Having these items on hand can save a lot of time and money.
Etrailer parts are top quality and best online price.

after one year - these products are working as they should, no need to adjust the brakes. Easy to install and worth the price.

by: Gerald J. 01/01/2014

These are well built, easy to install brake assemblies. I had to adjust them after installation as they would not self adjust as the video states. They will be great if they do auto adjust as they wear. Price was great and they arrived in three days after my order. I will buy all my trailer parts from etrailer in the future.

by: Frog Racing 07/04/2014

Perfect replacement for my 24ft Hallmark trailer. Very easy to install, just bolt on and connect the wires. With the automatic adjustment there is nothing else to do! I recommend putting some extra anti-seize to be on the safe side (I had similar brakes seize up after a big winter in the North East). Also you will need 2 plugs per assembly to cover the adjustment holes (the brakes don't come with any plug and have 2 holes!)

Hi.. thanks for the follow up.. Great products and service. Will always use you guys for my trailer supplies.

by: Stan 07/17/2016 One Year Later

I bought a trailer that had been home-fabricated using the axles from an old horse trailer. The axles had the remnants of electric trailer brakes, but the guts were missing. I was preparing to move from Pennsylvania to Montana, and intended to tow the trailer with a boat and some loose ends, and I wanted to have the security of brakes. Although I had never attempted to do an installation of this type, there were some helpful youtube videos to guide me. The installation went well, albeit slowly, mostly due to my inexperience, and the brakes proved to work well. The drive west was smooth, and the trailer has proved to be very useful out here. As far as I can tell, everything continues to work perfectly.

What Is The Difference Between the 6K and 7K Dexter Axle Electric Brake Assemblies
You are correct, the difference between the Electric Brake Assembly for 6K Axles, part # 23-458 / 23-459 and the Electric Brake Assembly for 7K axles, part # 23-180 / # 23-181, is that the 7K brake assembly has a stronger magnet, and also has a different compound on the brake shoes than the 6K electric brake assemblies for more stopping power. Both the 6k and 7K brake assemblies, fit the same axle. Yes, the 7K backing plates on part # 23-180 / 23-181, will fit on 6K pound axles.

When Do Brakes Need to be Added to Both Axles of Tandem Axle Trailer
There really isn't a particular maximum trailer weight that is used to determine when brakes need to be added to both axles of a tandem axle setup. While I do still recommend checking your local laws, I am also not aware of any general laws that indicate when brakes need to be put on all axles of a multi axle trailer (only laws that state when a trailer needs to be equipped with them). With all of this in mind, we always recommend adding brakes to both axles of a tandem axle trailer....

Do Nev-R-Adjust Brakes and Self-Adjusting Brakes Work the Same Way
Nev-R-Adjust is Dexter's specific trade name for self-adjusting brakes like # 23-458 and # AKEBRK-7L-SA. Self-adjust and Nev-R-Adjust are the same type of brakes. After their initial adjustment both will automatically maintain correct braking pressure. With self-adjusting brakes, the brake shoes are always properly aligned, so there's no need to manually adjust the brakes after the initial adjustment. As a result, you get optimum performance without having to take the time to continually...

Troubleshooting Weak Brakes on 2008 Everest After Having Bearings Repacked
Either they somehow got grease on your brakes and they aren't working because of that or the brakes are way out of adjustment. Are the brakes manual adjust or self -adjust? If they are self adjust they should start working again after a several brake applications while moving. If they are manual adjust you'd want to click the star wheel of the assemblies until you feel a light drag as you turn the wheel by hand.

Initial Adjustment Of Nev-R-Adjust Electric Brakes
When you install Nev-R-Adjust drum brakes like Dexter part # 23-458 and part # 23-459 the initial setup will be different. The Nev-R-Adjust has a small lever that prevents the brake star wheel from backing off as you do when you adjust standard brakes. With the Nev-R-Adjust brakes, you simply turn the wheel backwards after everything is installed, until you get a slight drag. If you continue turning the wheel it would keep adjusting the brakes until it locks the wheel. You would then...

Switching My Car Trailer From Hydraulic Drum To Electric Drum Brakes
Hey Mike, thanks for reaching out. I do agree that electric drum brakes do offer more control over your braking than hydraulic drum brakes. Electric brakes allow you to fine-tune your braking strength using the gain setting on your brake controller. The electric brake controller also gives you a manual override feature, so, much more control over your braking. If you are looking for a really good brake controller, I recommend the Tekonsha P3 # 90195 just since it is so dependable and easy...

Does it Matter Which Trailer Brake Assembly is Right and Which is Left
The braking performance will not be very good if you install brake assemblies on the wrong side of the trailer. The left side assembly is the driver's side (if the trailer were a car) and the right side is the passenger's side. The actuating arm that is attached to the brake magnet should be pointing towards the front of the trailer like in the picture I have included.

Dexter Brake Assembly Recommendations to Replace Part Number 023-357-00
The Dexter part number 023-357-00 is a 12x2 electric brake assembly. The correct RH assembly to use to replace what you have would be the part # 23-459 and for the LH assembly you would want the part # 23-458 if you have 6K axles. If you have 7k axles you would want part # 23-464 for the LH side and part # 23-465 for the RH side.

Should 7k Trailer Brake Assemblies be Used on a 6k Trailer Axle
Dimensionally they'll fit and they will operate but you don't actually get a stronger braking action. Instead the brakes will be harder to setup and get the correct amount of braking action. The heavier duty assemblies have a magnet that's more sensitive which helps with heavier weights but when used on a lighter trailer they become harder to setup and not anymore powerful. Best option is go to with 6k brake assemblies like the part # 23-459 for the right hand side and part # 23-458 for...

Trailer Brake Magnets Not Making Full Contact with Inside of Brake Drum
The brakes should still work fairly well. The magnets, when energized, cling to the armature surface of the drum and the rotations of the drum pull the magnet which then pushes out the shoes to make contact with the drum. If the brakes seem weak then you could adjust them out to be a little more aggressive to compensate for the little bit of the magnet not making contact with the drum. And if that still is not enough then you would need to replace the drums.

Replacement Bearings, Hubs, and Brakes For Dexter Axle On 2019 Jayco Eagle 25.5REOK 5TH Wheel Camper
Your Dexter axle needs the Bearing Kit # BK3-300 to fit the Hub # K08-201-98 that came on your axles. We do have the Dexter Nev-R-Adjust Electric Trailer Brake Kit # 23-458-459 if you are needing to replace the assemblies. They are also available separately Right # 23-459 and Left # 23-458 or as just the Right Shoes # K71-676 and Left Shoes # K71-675.

Replacement Hub and Bearing Kit for a 2016 Airstream International Trailer with a Dexter #11 Axle
From what I could find out, the Dexter axle you have on your Airstream uses an inner bearing # 25580 and an outer bearing # LM67048. With that being said, the hub you will need is the Dexter # 8-201-5UC3-EZ. This will include the bearings, seal, EZ-Lube grease cap, and lug nuts. For the left brake, you will need the Dexter Nev-R-Adjust Electric Trailer Brake # 23-458. This has a 5 bolt brake flange pattern and is for the left side of the axle.

Correct Replacement Brakes for a Dexter 23-459-01 and 23-458-01
I did some research and it looks like the only difference between your 023-459-01 kit and the Dexter Nev-R-Adjust Electric Trailer Brake Assembly # 23-459 is that your kit came with 33" leads and the other kits # 23-459 & # 23-458 do not. So, with that said, these'll work just fine to replace your original brakes.
