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.

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



by:

Replacement for 6000 lbs. original equipment brakes. Hoping for more stopping power as I usually tow near the limit of the trailer.
Installation was easy and straight-forward.
First impression is not much different but of course new brakes need to be burnished. The effectiveness is sure to increase. Overall happy :)



by:

Bought these Dexter because I wanted to replace unknown manufacturer of OEM brakes on newer fifth wheel. This product is "Made in USA" and quality is very good. My only complaint is that the rims of all four backing plates had severe scratches in the black paint and I repainted them before installation to reduce rusting. They got some rough handling somewhere. The shipping package was not damaged and each plate was wrapped in brown paper.



by:

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



by:

One of the assemblies failed with less than 1000 miles.

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

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.

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

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.


by:

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 etrailer.com, 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.

Packing was awesome, the last time I ordered brake assemblies from etrailer the packing was horrible. Brake pads had chunks missing from smashing into each other.



by:

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.

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



by:

Only three of the four parts arrived yesterday and I had planned on completing the work when the order arrived so the trailer was ready for this weekend's barrel race. I called and waited on line to find out that the last part will come a day later, Hopefully the drum comes in time to complete the work. Our UPS deliveries usually comes later in the day unfortunately.



by:

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!

Troy, the service rep that I dealt with on my most recent order from etrailer.com, 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 etrailer.com as a super place to get your trailer repair parts and accessories.

Completely Happy with the order, if there is anything that could improve i would have to say it could be better packaged. Otherwise no coplaints

They only shipped half of the order what the fuc. Is wrong with the people who are in charge



by:

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.



by:

Great product and etrailer has the BEST customer service! Thanks etrailer!



by:

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.



by:

I found what I was looking for and it was in stock. Simple purchasing and fast shipping. The break assembly is very simple to replace with this plug and play brake assembly.



by:

Quality OEM product, very easy install and Noah at etrailer was exceptional in guiding me to the correct brake assembly then processing the order which I received the very next day!

  • Trailer Hub & Spindle For 7,000 lb Axle With 12 Inch Electric Brakes
    First, thanks for all that detailed information, it was very helpful. And we can get you parts for your trailer, though the issue is that there isn't an available hub for your spindle due to what you mentioned - the uncommon 501349 bearing, which is for older agricultural spindles. There also isn't a 7,000 lb-rated hub with a 6 on 5-1/2" bolt pattern to go with your 7k-rated Dexter Nev-R-Adjust Electric Trailer Brake Assembly # 23-464 and # 23-465. So what that means is you'll have to...

    Hey Adam, thanks for the information! To replace your 12" x 2" Dexter 023-357-00 electric brake assembly you'll need the following parts: For a 6,000 lbs Axle Right Hand - Dexter Nev-R-Adjust Electric Trailer Brake Assembly item # 23-459 Left Hand - Dexter Nev-R-Adjust Electric Trailer Brake Assembly item # 23-458 For a 7,000 lbs Axle Right Hand - Dexter Nev-R-Adjust Electric Trailer Brake Assembly item # 23-465 Left Hand - Dexter Nev-R-Adjust Electric Trailer Brake Assembly item...

  • What Hub/Drums Are Recommended for Timbren 3,500 lb Axle Less System
    The Timbren 3.5k Axle Less System part # ASR35HDS02 that you referenced does require higher capacity hubs than what you currently have. For a hub/drum that is the same as your current hubs you would want the part # 8-201-9UC3-EZ. This hub comes with the correct fitting bearings for the Timbren axle spindle. For brake assemblies you would then want the part # 23-465 for the right hand side and part # 23-464 for the left hand side.

  • Replacement Brakes for Dexter 7k Axle
    Hey James! Thank you for providing that information. The correct left hand brake assembly is the Dexter Nev-R-Adjust Electric Trailer Brake Assembly - 12" - Left Hand - 7,000 lbs # 23-464. However, we do recommend replacing them in pairs for equal wear between the brakes. If you decide to replace both you need the # 23-464-465. What kind of trailer do you have?

  • Are 12"x2" Left Hand Brake Assemblies Available?
    Hi Robert! Single assemblies can be somewhat difficult to find on our website, but I have Dexter and etrailer options listed below. All are 12" x 2" left side electric brake assemblies, but the first set are manual adjusting and the second set are self adjusting. You didn't mention which style you were looking for, so I figured I would include both.

I gave my contact at Dexter Axle the serial number off of your tag and he said that the replacement brakes for your #12 torsion axle include part # 23-180 for the left hand side and part # 23-181 for the right hand side. If you would like to upgrade to the Nev-R-Adjust brake assemblies then you would need part # 23-464 for the left hand and part # 23-465 for the right hand. The advantage to the Nev-R-Adjust assemblies is that you don't have to manually adjust...

For a replacement bearing/race/seal kit, you'd use part # BK3-200, which includes the 14125A outer bearing, the 25580 inner bearing, the 10-36 grease seal and a replacement cotter pin.

  • Will Dexter Brake Assemblies Fit on a Lippert Axle
    You will have no problem using a Dexter brake assembly on a Lippert 7K axle. We have installed several Dexter brake assemblies on Lippert axles at our shop. Lippert and Dexter use the same standard mounting pattern and brake sizes. If you want standard brake assemblies, you could go with the Right Hand brake # 23-181 and the Left Hand brake # 23-180. I recommend stepping up to the Dexter Nev-R-Adjust brakes, # 23-465 and # 23-464. The cost difference is very minimal compared to the standard...

  • 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.

  • Can Manual Adjusting Brakes Be Swapped out for Self-Adjusting Brakes
    Yes, the self-adjusting version of the Dexter Electric Trailer Brake Assembly part # 23-181 is the Dexter Nev-R-Adjust Electric Trailer Brake Assembly part # 23-465. 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. The Dexter Nev-R-Adjust Electric Trailer Brake Kit has self-adjusting brakes meaning you do not have to turn the adjuster screw for even brake pad wear after the initial...

  • 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 Self Adjusting Brakes for B12E-01 Axletek-12-GG Electric Brake Assembly
    You can use the # AKEBRK-7-SA to replace your existing Axletek brakes and they'll work well for you. This is a self adjusting set of brakes and will fit on your existing hubs; you'll also need brake mounting hardware, which is available with part # BRKH12S. If you wanted to go with the Dexter Nev-R-Adjust brakes, those are available with parts # 23-465 (RH) and # 23-464 (LH). I've linked a short review video of these brakes for you to have a look at.

  • Should Brake Shoes Be Replaced If They Have Been Exposed To Grease
    Believe me I know how much of a pain a blown seal can be. Cleaning the shoes can be very tricky, and in some cases it can be impossible to get the shoes completely clean. We do recommend at the very least replacing the shoes, or just replacing the whole brake assembly. What you have there are the Dexter Dexter Nev-R-Adjust 12" Brake Assemblies. The part number in your picture indicates it is a left hand assembly # 23-464. We do offer replacement brake shoes for these in part # K71-675....

  • 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.

  • 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...

  • 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.

    I can help you try and figure out why your Dexter Nev-R-Adjust Electric Trailer Brake Assembly like parts # 23-465 and # 23-464 are locking up and there are a multitude of reasons. When this happens it is often an electrical issue or the brake magnets so check out your 7-way to ensure there is no corrosion which will be white or green which may be hampering the functionality of your brakes; if so, clean as necessary and that may resolve the issue. Next, you need to use Digital Multimeter...
