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!


Again etrailer is my go to online trailer parts supply store. I fix a lot of trailers and etrailer always has what I need at competitive prices.


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


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


Great service-Received order a day before original delivery date which was fast anyways!


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.


This product came fully assembled and fit my trailer perfectly.
Very satisfied with this product. The only thing better than this product is the customer service I received from Amy.

Absolutely perfect. Completely satisfied
Bill - 03/27/2022


I put these brakes on my 14000 lb.trailer on year ago and have no problems.Very good product.


OEM replacement, worked great.


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

Not good , they all got contaminated with grease what a mess.
JAYANT P - 10/20/2021


It works great, I replaced the manual brake adjuster with this automatic brake adjuster. My brakes are always adjusted, one less thing I have to do.


Easy to install, works great!


Awesome customer service,quick shipping, and my sales associate William B was great.


Worked with Paula-What a nice,kind & very helpful person was She! Paula got the order right and explained what to expect-Thanks Paula Will be asking for your kind help next go/around. Michael


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!
Charlie P - 12/27/2017


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!

Still operational, no problems.
Russell K - 11/16/2016


Very friendly professional staff to deal with!


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.


works as it is supposed to work. No issues.
ROBERT E - 08/28/2020


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.

Products are still preforming as expected
Jim I - 09/10/2018


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.

Product working great
Don B - 07/18/2016


One of the assemblies failed with less than 1000 miles.


Awesome service and support.


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


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


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.

  • 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.

  • How to Determine the Right Replacement Grease Seal for a Trailer
    The seal needed is going to depend on the inner and outer bearing numbers stamped into the sides of the bearings. Or if you know the part number of the hub I could look it up to determine the correct seal. The grease seal though is meant to hold the grease in the hub and not let it leak out the back of the hub. If the drum is filling with grease then it is leaking out somewhere else. You will need to make sure that the correct bearings and races are being used. There are some measurements...

  • Can Electric Trailer Brakes for 7,000 Pound Axles be Used on a 4,500 Pound Trailer
    You might be able to use 7K brakes on your trailer provided that the drums used are large enough and that the mounting pattern for the brake assemblies matches the pattern on the brake mounting flanges on the axles. Brakes for 7K axles are going to be 12x2 inches and have a 5-bolt mounting pattern. You will likely find though that the brakes will be overly aggressive on lighter trailers. It is recommended to use brakes that are of the appropriate capacity for your trailer's gross trailer...

  • Installation of Electric Trailer Brake Assemblies and Importance of Orientation
    The braking will not work as well because the primary brake shoe will not be in the correct location and you may also experience premature brake shoe wear because gravity will pull on the magnet lever slightly activating the brakes while driving. The assemblies are labeled for the correct side to avoid that issue. For instance the Dexter Nev-R-Adjust Electric Trailer Brake Assembly - 12" - Left Hand - 7,000 lbs # 23-464 should be installed on the driver's side. I've attached a video...

  • Replacement Trailer Brake Assemblies for Dexter 7k Automatic Adjusting Assemblies
    The brake assemblies you have are Dexter 12 inch assemblies with a 7k capacity. That means the current part numbers you would want are # 23-464 for the left hand side and part # 23-465 for the right hand side. The part # 23-464-465 that you referenced actually is both of these assemblies kitted together.

  • 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.

  • 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...

  • How to Determine the Right Replacement Brakes for a 2005 Keystone Challenger 5th Wheel Trailer
    Dexter Nev-R-Adjust electric brake assembly # 23-464 for the left side and # 23-465 for the right side are designed for 7,000 pound trailer axles. These are 12 x 2 inch brakes. If you have 7,000 pound axles then you can measure the inside of the brake drum. If the inside diameter is 12 inches and the inside width is 2 inches then they will fit.

  • Will Hydraulic Brake Hubs Work With Electric Brakes
    My contact at Dexter said that the hubs will be the same for hydraulic and electric brakes on their 7,000 pound axle. For electric brakes for your 7,000 pound axles, I recommend the 12 Inch Dexter Nev-R-Adjust Electric Brake Assembly # 23-465 for the right hand side and # 23-464 for the left hand side. These brake assemblies do not require any manual adjustments to be made, they automatically adjust to deliver optimum performance. I have attached an installation video of these brakes for you.

  • Recommended Brake Assemblies for 7,000 Pound Trailer Axle, 2009 Heartland Bighorn 3370RL
    It is best to confirm the axle capacity before purchasing brake assemblies. There should be a sticker or label on the axles with information such as their capacity. If you do find that your axles are 7,000 pound axles, I recommend using the Dexter 12 Inch Nev-R-Adjust Electric Brake Assembly, left hand side # 23-464 and right hand side # 23-465. These brake assemblies automatically adjust to provide optimum performance and braking power. In addition to eliminating the need for brake adjustments,...

  • Recommendation for Replacing Electric Brakes on a 7k Dexter Axle with Brakes Mounted Upside Down
    The brake assemblies like the 12 inch Nev-R-Adjust Electric Brake Assembly, item # 23-464 and # 23-465, that you ordered, are designed to be installed with the brake magnet below the axle, not above. We cannot recommend installing the Nev-R-Adjust assemblies upside down. I would check the axle. If it is a straight axle with no arch in it, then the axle has been installed upside down. If it is an arched axle with the bend oriented upwards, then the mounting flange has been welded on upside...

  • 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.

  • Dexter 7,000 lb Rated Brake Assembly Recommendation for Trailer
    Dexter would be the final authority on the capacities of their axles. For 7k rated Dexter brake assemblies you would want the part # 23-465 for the right hand side and part # 23-464 for the left hand side. What you described is not uncommon for Dexter axles. There are other instances where the difference between the capacities of two axle setups is either the assemblies or the hubs they put on them.

    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...
