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.

Received the brakes within 4 days.. Finally got around to installing them on my 5th wheel. Nothing to it..perfect fit. Will order again from etrailer!!

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



by:

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!)



by:

they look to be in order everything is here but do to weather I can't install them just yet so i'll have to get back to you



by:

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.

Best brakes ever owned, they operate better than the orig. brakes and seem to stay adjusted very well. I never have to adjust and easy to install.



by:

changed out both sides with new; bearings, seals, outside dust caps, and adjusting electric brakes: 1. parts were as described and fit, 2. easy to install new ones, and 3.they have been working fine without any problem. Great videos.

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



by:

Everything good with product. Shipping USPS sucks , stick with ups, Rachel was awesome.



by:

The electric trailer brakes arrive within three days of ordering. The parts were a perfect fit. Etrailer' support is second to none! Helpful videos and live support available. The four trailer brakes were $100.00 less expensive than the nearest competitor and free shipping too!

happy with the product fit great

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.
Thanks

Great availability and really fast shipping. Bolted right on!

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.



by:

Best thing about this brake kit is it's made in the USA. No hassle ordering and quick delivery. Did the front axle this month, doing rear axle next month.



by:

quick shipping, easy to install. very p leased!



by:

Perfect fit. Easy installation



by:

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.



by:

Excellent experience. Delivered on tim e!



by:

E-Trailer had exactly what I needed and it shipped the same day.



by:

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.



by:

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!



by:

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:

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:

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:

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.

Very nice product but installation instructions could have been more complete

  • Replacement Brakes and Nev-R-Lube Bearing for a 6K Dexter Axle

  • 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. Either way though I'd recommend speaking with the shop you had work on the...

  • 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.

  • 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...

    Hi Robert! Single assemblies can be somewhat difficult to find on our website, but I have Dexter and etrailer options listed below.

  • 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...

  • Which is Best Brand of Trailer Brake Assemblies
    Dexter brand trailer axle components are considered by most people to be the highest quality around. Whenever possible I recommend them over the other brands.

It won't require finding new connection points for your springs, building outer wells, or adding different springs. So consider this Plan B.

  • 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...

    We have the correct fit for your Dexter electric brake assemblies k23-466-00 and K23-467-00 (Canadian) replacements meeting US standards. You will use the Dexter Nev-R-Adjust Electric Trailer Brake Kit - 12" - Left and Right Hand Assemblies - 6K # 23-458-459 to buy a set or you can purchase them individually using # 23-458 for the left and # 23-459 for the right side.

  • 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. I recommend the Seal Puller # PTW1219 and Install Set # PTW83020 to make changing the bearings and races easier.

Both of these brakes have a 6,000-pound capacity and will have enough weight capacity for your 5200 pound axles.

    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.

  • Will Water Damage Magnets if Electric Brakes are Installed on Boat Trailer
    Electric brakes, like the Dexter Nev-R-Adjust Electric Trailer Brake Assembly # 23-458 that you referenced, are actually becoming more and more common on boat trailers. They used to not be so common because water and electricity don't play nice together, but if you unplug the trailer before backing it into the water you will be just fine. Any trailer components that are submerged under water will wear quicker than parts that are not, but if you make sure to hose down your boat trailer...
