These things are major time-savers! Bolt the whole assembly on, wire it up, and go! Can't beat the price either - would cost quite a bit more buying the parts individually. Made a huge difference in stopping power on my 18' Dively car hauler, 9990 GVWR. The brakes were 6 years old at the time, and had tens of thousands of miles on them - abusive miles too, with shoes seizing and dragging, electrical failures causing some to work 3x as hard as others, stop and go MA traffic, etc.

While I was at it, I also grabbed 30' of Deka jacketed 2-wire 10 gauge brake wiring, and redid the whole system from the plug back. I also removed the drums, had them turned at a local garage, and installed brand new bearings, races, & seals. The improvement in stopping power was nothing short of amazing.

I went from having my Tekonsha P3 on boost level 3 at 11 volts +, trailer UNLOADED, to running boost level 1 at 6 volts with 4,000 lbs. on the 2k lb. trailer! BIG difference in stopping power!


The products were excellent however, I ordered 2 each of #23-180 and 2 each #23-181. I received 3each #23-181 and 1ea #23-180. etrailer is sending me the correct one but it will take about a week to get in stock, then shipping time to me. I have already paid the service person for a service call of $xxx for the repairs, now I have to pay him another $xxx to come back when the correct one is received. I don’t understand how this could have happened except for someone not paying attention when getting my shipment ready. Needless to say I am very unhappy I have to pay the service person for two service calls due to someone not paying attention when getting the order ready for shipment.


Worked perfectly. Made several trips with my 42ft 5th wheel and brake assembly held up.


Product as advertised but I paid for 3 day shipping but it took four days, not a big deal ordinarily but we were on a dead line and as a result it could not be installed prior to our camping trip. I will now have to make another service appointment, wait for it and then pay for additional labor since the shop was doing he wheel bearings and would install it at no extra charge.


Great customer service and fast shipping


Haven’t installed it yet but have every reason to believe it will be fine. Everything we’ve ever ordered from etrailer has been a perfect fit for our camper. Will continue using etrailer


Exactly as described and high quality made in US. Buy USA made only!


Ordered a right hand brake assembly and received a left. Called for a replacement and a new one was shipped but it puts everything behind schedule.


Very disappointed in the time it took to get this product shipped from your location


Works as it should.


The product was shipped promptly. The product was described accurately and fits perfectly. I've been very pleased with the products and services I have received from thank you very much.


The brake assembly was exactly what I ordered. Direct bolt on and cheaper then buying the parts individually. etrailer did a fine job in packaging the product for shipping.


Very fast shipping, brake assembly as described and with a very good price compared to others. Will keep etrailer in mind for future purchases. Thanks, etrailer. Ron M.


Extremely fast shipping
Excellent p


Bought brake replacement kit for 20 ft gooseneck trailer, exact fit


Parts were as described and fitment was perfect. The guys and gals at etrailer have what you need and know there parts!


Excellent quality, part of a package that was delivered a few days after ordering


High quality Dexter parts at great prices. Along with fast shipping, what's not to like about buying from etrailer!


Products were fine and fit. It took a little longer then I was told to get the parts, the only problem was the shipping when the box came it was in bad shape and looked like it had been rolled of the truck.


The assemblies were perfect, fast ground shipping, put them on the day they arrived- no issues.. Oh yeah wire them before you put the drum on- much easier


Exactly as expected, plus great customer service correcting my order after I accidentally completed my online order of four right hand instead of two right and two left. Fast shipping, A+ experience.


The brakes have been on the horse trailer for a year now. They work great.


Parts were delivered on time and were exactly as expected. Everything fit and functions as desired. This was my third experience with e trailer, and customer service was once again second to none.


This is a good product and easy to install. Delivery was really good it got here a day early. I'm satisfied


fair price, good service, will buy from e trailer again, thanks job done

  • How To Determine Left and Right Side Of Trailer When Adding Braking Assemblies
    When determining the right and left side when adding brakes it is determined if you are standing behind the trailer looking towards the tow vehicle. The left side is the drivers side and the right side is the passengers side.

  • Bolt Hole Spacing on a 5 Bolt Flange and Pilot Hole Size on Dexter Electric Trailer Brake
    On a standard 5 bolt electric brake like the Dexter Electric Trailer Brake Assembly - 12" - Right Hand - 7,000 lbs item # 23-181, The bolt holes measure 3-7/8 inches from one corner to its diagonal counterpart. From hole to hole across the bottom is 3 inches and between the others is about 2-1/8 inches. The center hole of the brake assembly measures 3-3/16 inches across. I have attached a diagram of a standard 5 bolt brake mounting flange to give you a drawing of the dimensions you're...

  • Could Dexter Brake Assembly Fit Behind Warner Hub/Drum
    You'll need to check the bolt pattern of the brake assembly mounting flange that you have on your trailer currently to see if the # 23-181 would fit. The bottom two holes will need to be 3 inches apart and the other holes would need to be 2-1/8 inches apart like what you see in the picture I attached.

  • Are Dexter Electric Brakes Made in USA
    Yes they are! The Dexter Electric Trailer Brake Assembly # 23-180 (Left Hand) and # 23-181 (Right Hand) are made in the USA; the accompanying photo is from one of these assemblies with the "Made in U.S.A." sticker on it. These electric brake assemblies are 12" diameter x 2" wide, fit 7,000 lb axles and have a 5-bolt mounting flange pattern. I have added links to video reviews of both brake assemblies as well as a link to an install of 12 inch electric trailer brakes for you to take a look at.

  • How to Pick Out Replacement Brake Assemblies for a Travel Trailer
    The best way to pick out replacement brake assemblies is to go with ones rated for the weight of your trailer, has the correct mounting flange bolt pattern, and will fit the hubs that you currently have. If your axles are rated for 7k, have a 5 bolt mounting flange, and have hubs that are 12 inch by 2 inch the part # 23-180 and # 23-181 would be the correct brake assemblies. I attached a help article for you to check out as well.

  • Replacement Brake Assembly Recommendations When Shoes and Magnets Need Replacing
    By the time you replace the shoes and magnets of a brake assembly you are better off just replacing the entire assemblies since you will end up spending the same amount of money and would be getting all new assemblies that won't require disassembly and reassembly. You would want the # 23-181 and # 23-180.

  • Can I Replace my Manual Brake Assembly with the Dexter Nev-R-Adjust Brake Assembly
    You will be able to use the Dexter Nev-R-Adjust Electric Assembly for 6,000 lbs. Axles # 23-459 for your trailer even though your axle is rated for 5,200 lbs. However, you are limited by the 5,200 lbs. capacity of your axles and cannot load 6,000 lbs. in your trailer because you installed this brake assembly. I do not recommend installing brake assemblies with two different ratings on your vehicle. While your trailer brakes will work, the Dexter manual adjust assembly # 23-181 rated for...

  • 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...

  • Which Replacement Braking Assemblies For Axle Using 12 x 2 AL-KO Brakes
    Based on the information you provided your trailer uses 12" x 2" AL-KO Braking Assemblies which are unique in the fact that they use a different bolt pattern than the typical 12" x 2" brake. For replacements you will need the 12" x 2" Electric Brake Assembly Left Side # 23-180 and Right Side # 23-181. i included videos for each of the products mentioned for you to take a look at.

  • Can 7k 12 x 2 Nev-R-Adjust Trailer Brakes be Used in Place of 6k 12 x 2 Inch Trailer Brakes
    We do have some 12 x 2 inch Nev-R-Adjust electric trailer brakes for 7k axles. Left hand side is # 23-464, right hand side # 23-465. Current pricing is listed on the product pages for these brakes. If your brake mounting flanges have the 5-bolt pattern then you can use the 7k brakes and they will fit the same drums as the 12 x 2 inch brakes for 6k axles. Even Nev-R-Adjust brakes have to be adjusted when first installed but after that they will adjust themselves. Otherwise you would have...

  • Replacement Electric Trailer Brakes for Dexter 7,000 Pound Trailer Axle
    For trailer brake assembly # 23-428 to fit the drum will need to have an inner diameter of 12-1/4 inches and a width where the pads touch of 2-1/2 inches. I have included a picture showing these locations in a drum. This brake also mounts on a 4 bolt brake mounting flange. The 12-1/4 by 2-1/2 is not a common size though. The most common size brakes for a Dexter 7,000 pound axle is going to be 12 x 2 inch that mounts on a 5 bolt flange such as # 23-180 and # 23-181.

  • 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...

  • Replacement Hold Down Springs and Pins for Electric Trailer Brakes
    It sounds like you are talking about the parts that hold the brake shoes down. These parts include hold down springs that have little caps on them through which the hold down pins are inserted. We have kit # AKBRKR-SHD which will work with AxleTek, Dexter, Lippert (LCI), IAC, and AL-KO 10 or 12 inch brakes with shoed widths of 2 inches or 2-1/4 inches. If you have different size brakes or you are talking about different parts let me know.

  • One Trailer Tire is Bald After a Short Period
    There could be a couple of reasons for this. 1. The brake assembly in that position could be adjusted too tightly causing it to drag going down the road you can use the Brake Adjustment Spoon for Drum Brakes part # W80630 to loosen it up and test it again. 2. Your brake controller could be on too high of a setting for the trailer. Sometimes if we forget to turn it down when the trailer is unloaded it will cause the tires to lock up. If that position is a little tighter in adjustment...

If your Dexter axle is rated for 6,000 lbs you would use the 6,000 lb set and if your Dexter axle is rated for 7,000 lb you would use the 7,000 lb set.

  • Replacement Brakes Needed for a #12 Dexter Torsion Axle
    Thank you for the picture! 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.

  • Which Brake Assemblies fit a 5-Bolt Brake Assembly Backing Plate on a 6K Axle
    I called my contact at Dexter and spoke with him at length about this. Mobile home axles are traditionally weld-on brake assembles that cannot be replaced. If they are actually bolt-on both the 6K and 7K weight capacities will work. Part # 23-105 and part # 23-106 are left and right side 6K capacity brake assemblies. Part # 23-180 and part # 23-181 are left and right side 7K capacity brake assemblies. They have the same mounting pattern and size. The 5-bolt brake assembly pattern is a...

  • What is the Difference Between the 7K and 6K Electric Brake Assemblies from Dexter Axle
    There are two differences between the 6K and 7K brake assemblies. For the 7K, they use a semi-metallic compound on the brake shoes instead of the composite compound, and the magnets are stronger. This gives the brake assemblies more stopping power. They fit the same axles and spindle mounts, the only difference is how much weight the assemblies can safely stop. Choose the brake assemblies that have the weight requirement you need. 6K Left: 23-105 6K Right: 23-106 7K Left: 23-180 7K...

  • 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.

    Whether you have the 7K Dexter brake assemblies like part # 23-181 or like the Nev-R-Adjust # 23-465, you may simply need to adjust the brakes. Even if your brake controller is set to the highest setting, if your brakes are not adjusted properly then they will not perform correctly.

The correct replacement is # 23-26-27 which includes both the right and left side assemblies, all mounting hardware as well as the adjuster plugs. If you prefer to not have to manually adjust the brakes every so often, I recommend upgrading to the Nev-R-Adjust version of the same brakes which is part # 23-468-469.
