OEM Dexter parts well worth the cost. Brakes are very important in the scenarios I use my trailer. You definitely feel 6 brand new brake setups behind you! etrailer kept me well informed through the process on order status. Shipping was quick. Will be shipping etrailer for any of my trailer stuff going forward.


etrailer always the best service with quality products. Brake assembly is excellent quality.


My 40' 5th wheel came with Dexter axles & manual adjust brakes. They were a constant pain to get adjusted evenly and so they didn't overheat. These self-adjusting brakes are an easy upgrade. No more uneven brakes, even when applied hard. If I get another trailer with manual adjust brakes I will upgrade to these first thing. The best upgrade I've done on my 5th wheel in the past 5 years.


Quinn did sn excellent job on my order We compared pricing and informed me as to del8very times, I received email updates and was informed as to when to expect delivery. Oustanding and professional customer service, Highly recommend etrailer your trailer needs.


Exact replacement and the installation was easy. You will need to do a few stops from about 40 mph using the trailer brakes for the new brakes to adjust.


Amazing place to order from. Order came a day earlier than scheduled.


My issue “IS NOT” with etrailer, whom I cant say enough good things about! Always great customer service and fast shipping, etc.

My issue is with Dexter. My brake assemblies arrived with damaged wires due to the way they were packaged. The boxes were not torn up so UPS wasn’t hard on them in shipping, its the simple fact the wires are on the bottom with the weight and pressure from the brake assemblies laying on them. More care needs to be taken by Dexter to protect the wires in packaging for storage/shipping to the consumer. The wires are a critical component for electric brakes to function.

You can’t just stop in the middle when you have everything torn apart and send them back, so I rectified the problem as best I could with some marine heat shrink, but I should not have to be fixing anything on brand new parts!


Great product ordered another one!


Love the dexter brakes, however their packaging is inadequate. Out of the 4 brake assemblies I bought 2 of them were partially disassembled.

Oh no! Customer Service will be in touch to assist you.


Everything was there when we got the order. Everything is as advertised. Very satisfied



I have pulled my 5th wheel trailer at least 4000 miles since the brake rebuild. Everything has only improved. Brake pads seated in and the brakes work great. Having all new parts does give me a feeling of confidence in the Colorado Mounatins.


Troy, the service rep that I dealt with on my most recent order from, did a fantastic job helping me identify the exact parts I needed to replace the wheel bearings and brake assemblies on my 40 foot Big Horn 5th Wheel. I believe the prices were very reasonable and the service was faster than I expected. Thanks Troy, and I'll definitely recommend as a super place to get your trailer repair parts and accessories.

All the products are working well!


Definitely could have been packaged so the brake assemblies were not contacting each other during shipment. They were not damaged, but some packing material between the assemblies is preferred. These are direct replacements/upgrades for my 2013 Fuzion 2 axle 5th Wheel 12x2 electric brakes. Dexter makes quality products and these are of their usual top quality! Highly recommend these as a replacement/upgrade because stopping is a wonderful thing!

Russell K.


Still operational, no problems.


I ordered a set of brake assemblies for a dual axle 14K # trailer on Thursday with expected delivery on late Monday or Tuesday & they were delivered 2 pm Saturday. I was amazed at the prompt service with parts well packed in 2 boxes. Now-a-days when money is tight we order online & take a chance on anything to save a dollar....the biggest surprise....Made in USA...Thank you so much for supporting American Industry.... 2nd time ordering from etrailer & same great service.

Don B.


Product working great


Faster delivery than originally scheduled. Good product. Installed easily.



After a year and several thousand miles of towing we have had no further brake issues after installing this. Very happy! Great product!


I bought replacements for all four wheels, even though only one of the originals was broken. I have only replaced the one that was broken, holding the others in reserve.

That said, I am very happy with the one I installed. As with any items I have purchased from, I am happy with the quality of the products, the speed with which those products arrive, the cost of the products, and the convenience of purchasing from them.

I will continue to purchase from this company and tell my friends of their products.

Thank you.


Robert E.


works as it is supposed to work. No issues.


I ordered these as replacement brakes for our 42' (21,000 lb) camper. I AM SO HAPPY! My braking capabilities have improved over the standard non-adjusting model by 100%. They have performed great. I actually can stop for yellow lights.

Jim I.


Products are still preforming as expected


Easy to install.


One of the assemblies failed with less than 1000 miles.


Shipment was on time. Quality of product was excellent will recommend your company to anyone thank you for helping us get the right parts


These are the OEM Dexter brakes the only one anybody should use, excellent product. Greg S. Was very spot on for my order processing. My order came fast as can be thanks to Greg and all the back support team involved. Thank you

Jayant P.


Not good , they all got contaminated with grease what a mess.

Etrailer Expert

Heather A.


It sounds like you may have a broken grease seal. It looks like you may have a 7,000 lb Dexter axle. You will need to measure the part of the spindle where the grease seal rides. If it measures 2.125" you will need part # BK3-210. If it measures 2.25" you will need part # BK3-200.


Great job was delivered a day early 687 miles away nice job


I must tell you, my fellow etrailer shoppers and handi-man repair individuals that approx. 1 yr. ago I purchased 4- Dexter Nev-R-Adjust Electric Trailer Brake replacement assembies for my Big Horn 36ft. 5th wheel from etrailer and had the pleasure to be connected to customer service Rep. Phyllis L.. Phyllis went out of her way to make sure that I would receive the correct parts needed to get me on my way to our snowbird location 2200 miles away from home! The Dexter trailer brake assemblies were very easy to install and the initial adjustment was simple. 5000 miles later they are working very well.
Thanks etrailer , Phyllis L.


Seems good. Right fit, did what it's supposed to. Haven't driven down the road yet.


Easy to install and have used on several trips since then. I would buy this product from etrailer again without hesitation!


Excellent customer service and the brake units work great!

Jerry R.


I traded last summer for a new one but the brakes worked just fine.

  • Info Needed to Find Self Adjusting Trailer Brakes
    The Dexter Nev-r-Adjust assembly part # 23-464 is a self-adjusting 12 inch by 2 inch assembly for a 7,000 lb axle that has a matching right side of # 23-465. If your trailer has a different size/capacity need let me know what that info is and I will set you up with the parts you are in need of. I attached an install video for the assemblies mentioned as well.

  • What is the Purpose of the Plastic Piece the Wires Go Through on an Electric Brake Assembly
    That appears to be a plug that the wires go through when passing from the inside of the assembly to the outside. It is present so that the wires do not get cut on the metal.

  • Spindle, Brake Assembly and Hub/Drum Recommendations for a 5 on 5 and 8 on 6-1/2 Bolt Pattern
    You will need to use two different spindles/hubs/brake assemblies for each set of wheels. Which would make sense since you plan on swapping to a different axle. Spindles aren't something that are easy to swap in and out so your best option would be two have two totally different axles. For the 5 on 5 setup you would want the spindle part # TRU74FR. For a hub and drum part # 84556UC3, and brake assemblies # 23-27 for right side and # 23-26 for left side. For the 8 on 6-1/2 setup you would...

  • Electric Trailer Brake Assembly Recommendation for 6K or 7K Axles with 8 Lug Bolt Pattern
    The Dexter 6K and 7K axles are very similar to each other, so it can be difficult to determine their capacity just by looks. Dexter axles typically have a specs plate near the center of the axle, but there is a chance that it could have come off. The next place I would look for an indication of the axle capacity is the identification plate on the tongue of the trailer. There should be a plate that lists the Gross Vehicle Weight Rating (GVWR) and Gross Axle Weight Rating (GAWR). That should...

  • Can 7,000 lb Dexter Nev-R-Adjust Trailer Brakes be Used on 6,000 lb Axle
    Yes, so long as your 6,000 lb Dexter axle has a 5-bolt brake mounting flange (which it should), then you can use the Dexter Nev-R-Adjust Electric Trailer Brake Assembly - 12" - Right Hand - 7,000 lbs # 23-465. If you also need the left hand side the correct part number is the Dexter Nev-R-Adjust Electric Trailer Brake Assembly - 12" - Left Hand - 7,000 lbs # 23-464.

    The difference between Dexter Nev-R-Adjust Electric Trailer Brake Assembly - Right Hand # 23-465 with Left Hand # 23-464 and the Dexter Electric Trailer Brake Kit - Left and Right Hand Assemblies # 23-180-181 is that the former is self-adjusting while the latter is manually adjusting and will require Brake Adjustment Spoon for Drum Brakes # W80630.

  • How Do Dexter Nev-R-Adjust Electric Drum Trailer Brake Assemblies Work
    Besides the initial adjustment, which is not required but still recommended, you will not need to adjust the Nev-R-Adjust Electric Brake Assembly, # 23-464, unless you wanted to. According to Dexter, during travel, the brakes will automatically rotate an adjuster assembly to close the gap caused by lining wear. The brakes will remain in the optimum braking adjustment for safer braking. The Nev-R-Adjust Electric Brake Assembly for the right hand side is # 23-465.

  • Troubleshooting Dexter Nev-R-Adjust Brakes That Have Not Adjusted Properly After 300 Miles of Travel
    While Dexter Nev-R-Adjust brakes like the Dexter Nev-R-Adjust Electric Trailer Brake Assembly # 23-464 and # 23-465 can be manually adjusted, it is highly recommended that you do not manually adjust them. They were not designed to be adjusted that way and can be easily over adjusted and difficult to correct if over adjusted. Since you have said that you have already driven the trailer over 300 miles and they are still not adjusted properly, you likely have something else wrong. I would...

  • Recommended Axle and Suspension Upgrade for Converting Pop-Up Camper to Stand-Up Tear Camper
    In order to put a heavier suspension on your trailer you will need an axle, leaf springs, hangers, spring seats (if you need to move them), suspension bolts, U-bolts/U-bolt plates, and shackle straps (if you want a double-eye leaf spring). You will need to start with the axle, which will require the hub face to hub face dimensions of your current axle. While the spring seat to spring seat measurement can be helpful, it is possible to remove the spring seats and weld on new ones if necessary....

  • Replacement Grease Seal and Bearing Kit For a 2020 Grand Design Solitude 375RES With 7,000LB Axles
    Your Dexter axle on your 2020 Grand Design Solitude does use the Grease Seal # GS-2250DL. This seal is also found in our Bearing Kit # BK3-200 which I do recommend keeping on hand incase you have an issue while on the road. The kit contains the Seal # GS-2250DL, Inner Bearing # 25580, Inner Race # 25520, Outer Bearing # 14125A, and Outer Race # 14276.

  • Parts Needed to Swap to Self Adjusting Electric Trailer Brakes
    I may have a solution for yo, but there's not a way to add the parts to make your brake assemblies self adjusting, like the Dexter Nev R Adjust brakes # 23-464-465. However, when it's time to change the brakes out completely you can use the etrailer Self Adjusting Brakes # AKEBRK-7-SA and put the days of brake adjustments behind you. These will function the same as the Dexter Nev R Adjust brakes, they're just a bit more economically priced. You'll also need some brake mounting hardware,...

Based on the dimensions you listed you have a number 42 spindle so for a hub/drum to fit that you'd want the part # 8-201-9UC3-EZ and then for self adjusting brake assemblies you'd want the part # 23-465 for the right hand side or part # 23-464 for the left hand side.

This assembly is for the right hand side and if you need the left hand side you can use part # 23-464 or part # 23-464-465 for both right and left hand side.

  • Is it Okay to Use Nev-R-Adjust Brakes with Nev-R-Lube Hubs
    As long as the brake assemblies you are replacing are 12x2, you can certainly use the Nev-R-Adjust brake assemblies. The brake assembly and the bearing system you are using would be unrelated, so there is no reason why you could not use the Nev-R-Adjust assembly. There is also no reason why you could not upgrade to the 7000 lb capacity assembly like the # 23-464 and # 23-465. The brake shoes will be better and the magnet will be a bit stronger.

  • Will the Dexter 12 Inch Nev-R-Adjust Brake Assembly # 23-464 Fit on a 2007 Newmar Cypress 5th Wheel
    I spoke with the parts department at Newmar and he told me they only use Dexter brake assemblies on their trailers, so the Dexter 12 Inch Nev-R-Adjust Electric Brake Assemblies, # 23-464 (left) and # 23-465 (right), should work with your 7,000 lbs axles on your 2007 Newmar Cypress 35KSRL fifth wheel trailer. To confirm that they will work, you can compare the mounting bolt pattern of these brakes to the bolt pattern of your brake mounting flange or to your current brake assemblies.

  • Does the Dexter Nev-R-Adjust Trailer Brake Kit Come As a Pair
    Not a dumb question at all! Brake assemblies like the Dexter Nev-R-Adjust Electric Trailer Brake Kit - 12" - Left and Right Hand Assemblies - 7K # 23-464-465 are either sold in matching pairs or as single brake assemblies for either the left or right side of the trailer # 23-464 (left) or # 23-465 (right). This particular kit is sold as a pair, so if you have tandem axles on your 2014 Grand Design Solitude 305re you'll want to order 2 of these brake kits. Additionally, these brake kits...

  • Nev-R-Adjust Electric Drum Trailer Brakes for a Trailer with 7K Dexter Axles
    Most 7K axles are going to use 12 inch by 2 inch brakes. To determine if these are the right size you can measure the internal diameter of the drum and the width where the pads would make contact with the drum. I am confident that it will turn out to be 12 x 2 inches. For Dexter Nev-R-Adjust electric trailer brakes for 7K axles use # 23-465 for the right hand side and # 23-464 for the left hand side. These brake assemblies mount on a 5-bolt mounting flange. Even though these are Nev-R-Adjust...

  • Are Replacement Shoes/Linings and Magents Available for Dexter 12x2 Inch Nev-R-Adjust Trailer Brakes
    Yes, the brake shoes and magnets are available as replacement parts for 12 inch Nev-R-Adjust brake assembly # 23-464. Some brake assemblies have expensive replacement parts and on those it makes more sense to replace the whole assembly. For replacement shoes, left hand side use # K71-675 and for the right use # K71-676. The magnet is # BP01-225. The cost of a magnet and shoe/lining for one brake assembly costs more than the whole assembly. Going to disc brakes is a great idea. Not only...

  • Difference Between the Two Types of 12x2 7000 lb. Brake Assemblies
    The difference between the two brake assemblies comes down to one being self adjusting and one that is manually adjusted. I recommend the self adjusting because you will never have to crawl under the trailer to adjust the brakes. This can be a headache and we tend to not do it as often as we should which leads to poor performing brakes. With the self adjusting it automatically tightens as the shoes wear down keeping your trailer's braking performance optimized and working as safely as...

    For a hub/drum that does fit the Timbren Axle Less System part # ASR35HDS02 the part # 8-201-9UC3-EZ is the recommended hub. The hub/drum you mentioned will not fit on this spindle. The only hubs that will fit the # ASR35HDS02 have 6 and 8 lug configurations. For brake assemblies then you'd want the part # 23-465 for the right hand side or part # 23-464 for the left hand side.

We do offer replacement bearings, bearing kits and brake components as well. Complete bearing kits for 7K axles can be seen on the link provided.
