Exact replacement for the airstream 12x 2 brake assembly. Service and delivery were excellent.


Fit perfectly and easy to install


Did a remove and replace. Original Dexter Brake assemblies had curved wear and missing the brake adjusting plugs, getting dust and no doubt water in them from the Airstream plant in Jackson Center, OH. All EIGHT of eight wheels had them missing.

That was my Problem. Now the Cure:

etrailer had two Brake Assembly kits at my door three days after ordering. I installed them today and they work and had supplied five fresh locking bolts and the two plastic brake adjusting plugs.

I am one happy Airstream trailer camper. First time doing brakes on a trailer and it was much easier doing the complete assembly. Will break them in as suggested in their installation instructions.

I recommended on the that Airstream owners follow for information. One member already said he ordered parts, as he did not know how to find what he needed.

Excellent service ordering from my computer. Notice of parts being shipped was emailed to me. Parts were dropped off at my doorstop. If the carton had some glazed doughnuts included... it would have been 5% better.

George J.... you did me right as a first time customer.


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!)


Fast delivery, product fit perfectly and was just as discribed. Purchased 6 never adjust Assy's for 6000 lb axles. Much easier than replacing part by part.

Still working great with no issues


New brake assemblies were easier to install than just shoes and price was not much more than shoes. Excellent quality. Work better than originals.


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.


This part was an exact fit replacement. It has worked perfectly


I purchased the 12" auto adjust brake set for my trailer. They arrived in a timely manner and installation was VERY easy. 5 bolts and 2 wire connections and one unit done.

They worked as they should from the first use. I only took it around the block to make sure they worked as they should and they worked just fine.

If you need to replace your brakes I would look at these as they make it A LOT easier than just replacing the shoes although a bit more expensive, but then again everything on the backing plate is new and won't need to be replaced for a long time down the road.

Mike M.


I am real happy with them! I have an older double axel 29ft toy hauler thatonly 2 of the 4 brakes were working. So after installing the new brakesneedless to say it stops like it should!Im very happy with them and glad that they worked like they were supposedto!If I need parts again I check your site to see if you have it and go fromthere.Thanks again!


Quick shipment, super easy to install. Remove 5 bolts, cut the wires and the old one comes off. Tighten 5 bolts, reconnect the wires and put the drum back on.



Brakes are still working great, no issues!! Don’t forget to re-torque the wheels after a few hundred miles.


I ordered a Dexter Nev-R-Adjust electric brake assembly. Easy purchase. Great shipping. Super simple part to in install. If I need trailer parts again, I'll definitely return for more this great service and excellent parts.


This was a replacement for a Dexter brake that was on a 4 year old Airstream that had less than 9000 miles on it and proved to be defective. Dexter wouldn’t honor the 5-year warranty since I was the original owner. Service from etrailer was great but I wouldn’t select another Dexter product if there were other options.


I bought these for my 30' fifth wheel trailer. The product arrived quickly from Appears to be well made with quality components made in the USA. I have only completed one side so, I can not write about performance however, from my initial impression these will work fine.

Great J.


Its been a year since the install and I am happy to say all is well. One thing to note about these brakes is you must adjust them initially!. It will take a very long time to adjust them if you dont do the initial adjustment. The paint has not chipped nor do I see any signs of rust.


Wanted to wait until after our most recent trip with our trailer before giving you the one year follow-up. Just pulled the trailer almost 1000 miles in the Rocky Mountains. The Nev-R-Adjust brakes & drums worked great and I felt very confident in their performance. I really appreciate not having to crawl under the trailer to adjust the brakes. All are good products and I would recommend them to all.


We put these never adjust brakes on after we removed the manual adjust brakes from our Cargo Trailer converted to a RV. We then installed the never adjust electric brakes and broke them in according to the instructions. We then started and completed a 19,400 mile trip from Florida to California then to Washington then to the UP of Michigan then to the Adirondack Mountains of NY and then back to Florida. We never had a problem with the brakes. We visited 17 National Parks, 7 state parks and numerous national forests. Great trip with no problems.


Great product great price


Outstanding customer service and very fast shipping.


The conversion from Hydraulic to electric brakes was TOO easy. Totally completed 4 wheel overhaul (bearing kit BK3-110) and brake conversion (including wiring) in just over 3 hours. On the road and working AWESOME. Only item that threw me (not a big deal) the cotter pin in BK3-110 was too small for the spindle and nut. Had some the right size in the shop so no worries.


These Dexter fit the Lippert axles perfectly. I HAVE NOT road tested them yet, but wanted to leave a review regardless mainly because etrailer asked me to. These brakes are a good value, really, but they are packaged poorly in a large box with only some brown paper. They are pretty heavy and that means lots of banging going on in delivery. One of the pads had a chip missing and 2 were unassembled--cable and star wheel dislodged. I contacted etrailer and they sent me 2 new ones and emailed me a return label. All said, it was an inconvenience, but the price can't be beat. Again, performance has yet to be determined, but I'm obviously all in as they are mounted.


When I was looking for brake pads for our fifth wheel these came up as a very pleasant surprise. I had never seen these full brake assemblies before.

I had not done mechanical work for a good many years and these were perfect. All you have to do is undo five nuts, exchange old assembly for new and replace the nuts. You also have to splice the two wires for the electric brakes and you should be sure to use a heat shrink sleeve to keep the connection from corroding. BTW, you don't have to worry about polarity with the wires.

In short it takes longer to dismount the tire and hub than it does to change these out. Great.

Regrettably, I forgot to take pics but these make for a very clean job.


I purchased 4 of the 12" Nev-R-Adjust brake assemblies for my Cardinal becuse I have been having some squeaky and binding brake issues with the old ones. I was surprised at how quickly I received them. They are easy to install; just undo the old wiring, remove the five bolts holding the backing plate brake assembly and put the new ones on. These are a bit more expensive than replacing just the shoes but ALOT easier and more dependable. Unfortunately I have not had a chance to test drive the rig to see if this corrected the problem.
But take note that the two little rubber covers on the backing plate by the star wheel are not included. These must be ordered seperately.


So far so good. Instulation was easy and straight forward. Haven't had a chance to try them yet.


Bought a used skid steer trailer that needed all new bearings and electric brakes. It was easy to find the correct bearing kit on etrailer and installation videos on the site made it a breeze for a DIY'er.


Great item ready to go. Easy install


Easy change over. Just bolted them on and hooked up the wires adjusted,and was good to go. Thanks Hank

Henry W.


I have had no issues with the brakes after the change over to the self adjusting units.

  • Why a Bigger Trailer Magnet for Electric Brakes is not Always Needed
    Your best option for a brake assembly is the one that matches the capacity of your trailer. Yes, the 7k Dexter brake assembly # 23-181 is going to have a more powerful brake magnet than 6k assembly like the Brake Assembly part # 23-459, but having a more powerful magnet can make it more difficult for your trailer to stop smoothly as the bigger magnet will want to grab harder than the smaller one. If I were you I would just stick with the same rating brake assembly as what your trailer...

  • How to Determine Which Replacement Electric Brake Assemblies are Needed
    If you're looking to replace an existing brake assembly like part # 23-459, you'd measure the interior diameter and depth of your brake drum. For instance, the # 8-201-9UC3-EZ drum you referred to has an inside diameter of 12 inches and a depth of 2 inches. This means you'd need a 12x2 brake assembly. If you have a 6K axle, the # 23-458 (left side) and # 23-459 (right side) would work great. These are Nev-R-Adjust assemblies that won't need adjusting after the initial adjustment at installation.

  • 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.

  • Replacement 10 Inch Brake Assemblies for Kaufman Car Hauler
    For the cost of replacement shoes and the hassle of finding the right ones and installing them it is best to just replace the entire assembly. Your brake assembly size of 10 inch by 2-1/2 inch is most likely the size 10 x 2-1/4 inch as that is the closest size that is actually very popular. This size is very commonly associated with 3,500 lb axles. Which would most likely mean you have a triple axle trailer. For a set of self-adjusting brake assemblies you would need the part # AKEBRK-35R-SA...

  • Initial Set-Up for 12" Nev-R-Adjust Electric Brake Assemblies # 23-458 and # 23-459
    I want to start by thanking you again for your purchase. We truly appreciate your business. When it comes to the 12" Nev-R-Adjust Electric Brake Assemblies, # 23-458 and # 23-459, the mounting bolts, nuts, washers, and adjuster plugs are sold separately. For adjuster plugs you will need part # BP10-220. As for replacing the adjuster wheel with one from your older assemblies, it most likely will not work. Last but not least, the performance of the brake assemblies. Poor performance is...

  • Recommended Replacement Electric Trailer Brakes for Jamco 4 Horse Trailer
    To select replacement electric brake assemblies for your Jamco horse trailer you'll need to confirm a few details about your trailer set-up. First you need to confirm the axles' capacity to ensure your new brakes will have the required stopping power. Axles in Jamco horse trailers can be rated from 3500- to 8000-lbs. There should be a sticker on the axles that indicates the capacity. You also need to match up the size of the brakes, both their diameter and width, and confirm the mounting...

  • Do Self-Adjusting Trailer Brakes Require Reversing the Trailer for Adjustment
    Self-adjusting trailer brakes like the Axle Technology # AKEBRK-7L-SA and # AKEBRK-7R-SA do require an initial manual adjustment as you noted but after that they will automatically maintain the correct pad pressure with normal driving. The auto-adjust works whether you are driving in a forward direction or in a reverse direction. The automatic mechanism uses a fine-toothed gear that can make precise adjustments and saves you the hassle of re-adjustment after initial break-in.

  • Bolt Torque Specification for Mounting a 12 Inch Brake Assembly
    According to Dexter Axle, the attachment bolts for a 12 x 2 brake assembly should be torqued to 25-50 foot/lbs. If you don't have a torque wrench handy, if you tighten the bolts until the lock washers flatten out, you'll be pretty darn close to that range.

  • 12 by 2 inch Brake Assembly Recommendation for a Dexter 5,200 lb Axle
    For your 5,200 lb Lippert axles I would recommend the Dexter brake assembly part # 23-459 for the right hand side of your trailer and part # 23-458 for the left hand side. Both these assemblies are 12 by 2 inch assemblies designed to fit the 5 bolt mounting flange you have on your axles.

    I walked out to the warehouse to look at the Electric Brake Assembly for 6K Axles, part # 23-459. The brake assembly does not include the backing plate bolts. I would recommend installing new bolts and nuts for easier installation and safety. For mounting bolt, you would need Brake Mounting Bolt, part # 7-5, which is sold as a quantity of 1.

  • 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.

  • Brake Assemblies for 7,000 lb Axle
    In order to get the right brakes what matters is the weight rating of your axle and the size of your drum. Wheel size does not really matter so long as the brake fits inside your drum. For example, the Electric Trailer Brake Kit # AKEBRK-7-SA are rated for 7,000 lb axles and are 12" diameter x 2" wide, and fit that size drum; it is also important that you have a 5-bolt brake mounting flange so you can mount these brakes. If that is your drum size and you have that mounting flange bolt...

    Nev-R-Adjust drum brakes like Dexter # 23-458 and # 23-459 will self-adjust but initially you will need to make a manual adjustment using the star wheel and a brake adjustment tool # W80630. The initial tension setting you do manually should result in friction on the wheel you can hear and feel as you rotate the tire. After the initial adjustment you wont need to do any more adjustments because as you back up the trailer this will apply tension on the cable. In turn that cable will activate...

  • Timbren Axle Less Setup, Hub/Drums and Brake Assemblies Recommend for 10k Trailer with Tandem Axles
    You can run Timbren axle kits in tandem for a tandem axle trailer. For the Timbren setup you would want 2 sets of the part # ASR5200S01. For hub drums you would want the part # 8-201-5UC3-EZ which will fit the spindles and will give you a 6 on 5-1/2 inch wheel bolt pattern. For brake assemblies you would want the # 23-459 for the right hand side and part # 23-458 for the left hand side.

    I went ahead and confirmed with Airstream that you your specific model of Bambi could have a 3500 pound axle or a higher capacity which is where some of the confusion may arise. Since you already have the Dexter Nev-R-Adjust Electric Trailer Brake Assembly - 12" # 23-459 installed, this tells me that you have the higher capacity axles and not the 3500 pound axles. 3500-pound brakes are 10-inches in diameter while the higher capacity brakes are 12 inches in diameter (which you need).

  • How to Determine the Capacity of 2 Inch Square Axle
    Square axles can be tough to determine capacity since the same spindle can typically fit a range of axle capacities. With this being said the absolute best way to determine the capacity of your axle is to locate a plate/sticker on the axle itself or on the trailer. If this is not available we can take a few steps to try and narrow it down for you. 1) A 2 inch square axle using a 5 on 3-7/8 inch brake mounting flange is typical of 5,200, 6,000, and 7,000 lb axles.
