I am a big believer is sticking with original equipment parts when possible. Locally here in Canada the parts thatbI purchased frome etrailer were much more expensive. It took much longer than expected for the parts to arrive, but the quality, fit and finish was excellent. Following the burnishing in procedure the brakes functioned excellent. My trailer is a 7 Ton dump trailer with an empty weight of around 5000lbs. My gain was set @ 2 empty with excellent results is slowing the truck and trailer. I haven't pulled a full load yet, but I expect to have full confidence in the brakes ability stop the trailer safety in annorderly manner.


Received my order.....2 Dexter electric brake sets. Evidently the 2 boxes, left and right, did not fit in the shipping box. So they took one out of the box, slid it beside the boxed set, no plastic bag, padding, etc. Then they left the hardware kit out of the side they nuts, plugs, etc.....! Called Customer Service, they said they would put something together and send it to me. Haven't received a shipping notification as of yet. Good luck on my part! Will not order from etrailer again!

I would be frustrated as well! I am sending this to our customer service team to make sure they update you on that shipment. Thanks for letting us know.

Great fit, work as they should. Be sure to break in per Mfr. It really seats brake pads and allows breaks to function as they should on trailer. Much easier to replace backing plate with pads, etc. couple electrical connections and back in business.


I'm very unhappy My brake parts i ordered on October 6th was supposed to be here on October 12th and when I ordered them said they were in stock and after they took my money they sent email around 12th saying out of stock and you will not receive them till 20th to 24th and there answer was we will give you some cheap one's and we were leaving on vacation on 16th so drove all way to Orlando and back with no brakes on 20k camper and round trip was 1200 miles am so upset and could have ordered them from Amazon and had them in 4 days. Sales person was very sweet and I know it wasn't her fault.. I will never do business with them again.. Also ask them what they could do to make it better their answer was we'll give you your money back after i waited on them . By then it was too late...


Thank you ETrailer, parts all installed today on My Grand Design Reflection Fifth Wheel, the whole buying process was great and a Paul helped me get the parts I needed on the phone. I would highly recommend this company for trailer parts,, Great people, Thanks Again look forward to future purchases; John Donovan


These guys were great. We are from Ontario Canada and had some issues on our way to Florida. Great customer services. Some of our parts got shipped to the wrong location, but worked hard to figure out what went wrong and got our parts to us in time for us to return home. I would highly recommend e trailer for all your trailer needs.


Product exactly what I needed! Online catalog easy to navigate. Product shipped and received quickly. Will use every time for our toyhauler!


They where great on helping me get the correct information so I could get the right parts...will differently use them for all my trailers..


Perfect fit and excellent quality. That is why I use etrailer.


Great service, quick and parts in stock. A lot of our customers are rodeo cowboy/cowgirls and they need to be back on the road in a hurry. Waiting 2 weeks for parts don't work. Thanks eTrailer fo what you do~


No visible phone number. On the web sight
No place to leave a note or ask questions when ordering
I need to reuse the old bearings and seals for my time frame
Other wise they showed up on the delivery day and the assembly seamed complete
Hope things are good

Sorry about the trouble. Our customer service number is 800-298-1624. Here is where you can ask a question about the product:
-- Etrailer Expert Sierra K - 09/24/2021


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.


Installed on my new to me weekend warrior. Worked great! Thank you!!!


One assembly was missing the adjuster and two look like they have already been installed. Other than that they are exactly what I wanted.


Order was shipped with items missing. This caused us to have ro cancel our trip due to not being able to get the repairs done in time.

I am sorry to hear that. I will make sure to send your information to our customer service team to make sure you are squared away and not having to cancel any more trips.

Perfect fit, quick processing and delivery from etrailer. I've shopped here before and I'll continue to shop here in the future.

Fast service and exact parts!


Very knowledgeable and helpful fellows. Got just what I ordered and needed. Correct parts the first time. Great!

Excellent service. Excellent delivery timeline. Expert assistance. Everything was exactly what I needed and furthermore I can now adequately stop my trailer and mitigate running over the stray- animals that run out in front of me (<-- thats a joke!). I would highly recommend etrailer for all of your camper needs!


Easy installation and great customer se rvice


Great product good price fast delivery

Took like forever to get my order but thats what we get for relying on China for everything... etrailer did what they could to keep me informed....

  • How Many Brake Assemblies are in the Dexter Electric Trailer Brake Kit 23-180-181
    The Dexter Electric Trailer Brake Kit # 23-180-181 comes with a left hand and a right hand assembly. If you are needing 4 assemblies you will need to purchase 2 sets of this kit. You can check out the assemblies in the review video I linked for you.

  • Thickness of Brake Pads for 12" Dexter Electric Brake Kit and What is Minimum Safe Thickness
    The brake pads on the 12" Dexter Electric Drum Brake Kit # 23-180-181 are 3/16" thick. Dexter Axle recommends replacing them once they get down to 1/16" thick.

  • Troubleshooting Dexter 6,000 lb Axle Electric Drum Brake Adjustment
    What you describe for your brakes after adjustment is not normal. You should have a slight drag on your brakes when spinning the hubs by hand when they are adjusted properly. There shouldn't be any difference when rotated in the opposite direction, so having brakes engage makes me think there is a spring issue or a shoe alignment issue. There should not be any locking so that is a sure sign of an issue. If you put the assembly on the wrong side, that would give you stronger braking...

  • How To Determine Replacement Electric Trailer Brakes For Trailer
    I would be happy to recommend the correct replacement electric trailer brakes for you, but the 3175030707 did not cross reference to any brake assemblies. To determine the correct brake assemblies I would need to know the weight rating of your axle which can be found on the axle tag on the axle tube, and the diameter and width of your current assemblies as shown in the included picture. For example the Dexter Electric Trailer Brake Kit - 12" - Left and Right Hand Assemblies - 7,000 lbs...

  • How Long to Do Install of New Trailer Left and Right Brake Assemblies
    I'd set aside about two hours or so to do a brake assembly install like with the Dexter Trailer Brake Kit part # 23-180-181 if it's your first time doing so. It's not a hard process but if you wanted to take your time with it I am sure two hours or so would be adequate.

  • Will Dexter 7k Trailer Brake Assemblies Fit 5,200 lb Trailer Axles
    The 7k Dexter brake assembly set part # 23-180-181 will fit on your 5,200 lb axles and will have a bigger magnet. The problem you may find is that the bigger magnet might make it harder to get the brakes dialed in perfectly as they might come on too strong or too weak.

  • At What Interval Should Electric Trailer Brake Assemblies Be Replaced
    There's really no set hard and fast rule on the interval of time at which trailer brake assemblies should be replaced, but once the friction material on the brake pads gets down to about 1/16 of an inch or the magnet gets grooved or worn to the point where the copper wire inside of it is visible, that's the point where you'll want to replace them. If the face of the magnet has grooves worn in it, take a good look at the armature surface of the brake drum where the magnets ride against....

  • What Replacement Brakes do I Need for My Dexter 7k Axles?
    It sounds like you are looking for 2 sets of left/right side brakes for your 7k trailer. If that is the case, we unfortuantely do not carry the 23-181-00 because these are an older brake model that was discontinued from Dexter. However, the new models fit as well. Those are 2 sets of the # 23-180-181. These are direct replacements of your current brakes.

  • Help! Trailer Brakes Are Only Hooked Up On One Side of Axle
    Yes, you should be concerned about your trailer brakes being connected on just one side, but before you reach out to a dealership let's double check first. Electric brakes, like the Dexter Axle # 23-180-181, use magnets so when the brakes are activated there is a slight "hum" noise. Sometimes wiring is ran along the axle from one side to the other so you may only see the brake circuit going down one side of your trailer but all of the brakes are still connected to the circuit. If you have...

  • How To Determine The Correct Replacement Electric Drum Brake Assemblies For Your Trailer
    To find the correct replacement electric drum brakes for your 2007 Weekend Warrior LE3105 you'll need to know the axle capacity. To find yours you'll just need to look on the axles for the axle tag, which will tell you the capacity. Given that you have triple axles you most likely have 5,000 to 7,000lb axles, but you'll definitely want to check before purchasing anything. For example, if you had 7k axles then you could use the Dexter Electric Trailer Brake Kit # 23-180-181, which will...

  • 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...

  • No Trailer Brakes on 2018 Voltage Toy Hauler After New Brake Install
    I really suggest you just take the trailer back to the dealer and have them fix the issue because the second you try to fix their mistake, the warranty for the work they performed goes out the window. That said, if the brakes are humming then that means you are getting power. If the brakes are getting power but not engaging then the most common cause of this after a fresh install is that they have not yet been adjusted. There is a star wheel on the back for adjusting the tension on the...

  • Replacement Brake Assembly For 5,200LB Al-KO Axle
    Yes, the Dexter Electric Trailer Brake Kit # 23-180-181 will fit the 5,200lb AL-KO axles. I recommend the Dexter Nev-R-Adjust Electric Trailer Brake Kit # 23-458-459. This will allow the brakes to self adjust meaning less hassle for you adjusting brakes.

  • What Is The Difference Between Dexter Electric Brakes 23-180-181 and 23-105-106?
    The difference between the Dexter Electric Trailer Brake Kit - 12" - Left and Right Hand Assemblies - 7,000 lbs # 23-180-181 and the # 23-105-106 you mentioned are the strength of the brake magnets. The # 23-180-181 was designed for 7000lb axles where the # 23-105-106 was designed for 6000lb axles so it has slightly weaker brake magnets. They are both 12" x 2" brakes so they are interchangeable, but you will want to match them to the weight rating of your axle to make sure you get adequate...

  • How to Choose the Correct Electric Brakes for 20 Foot Flat Bed Trailer
    In order to find the correct electric brakes for your trailer you are going to need to know the axle capacity. You should be able to find this on your axle tag. Once you have this information you will be able to choose the correct brake assemblies for your trailer. For example, if you have tandem 3,500 lb axles then you could use the Dexter Nev-R-Adjust Electric Trailer Brake Kit - 10" - Left and Right Hand Assemblies - 3.5K # 23-468-469. These are self-adjusting brakes that fit a 10...

  • Can 7K 12 Inch Electric Brakes be Used for 8K Trailer Axles
    The Dexter Electric Trailer Brake Kit # 23-180-181 will work for your 8K axles if indeed your current brakes are electric, have a 12" diameter, and measure 2" wide. Standard 8K brakes like part # 23-402-403 though are hydraulic, have a 12-1/4" diameter, and measure 3-3/8" wide. As long as your specs match the 7K electric brakes you're good to go.

  • Do Dexter 7k Trailer Brake Assemblies Require Manual Adjustment
    When adjusting trailer brake assemblies like the Dexter 7k set part # 23-180-181 you want to tighten them down till there is a light drag on the wheel as you turn them by hand. To see how to manually adjust trailer brake assemblies check out the video I attached, fast-forward to the 4:35 mark of the video. Another option is a set of self-adjusting brake assemblies like the part # 23-464-465 which actively tighten as needed when you use them. These require no adjustment ever.

    Though I'm not quite sure what you are referring to in regards to a misunderstanding, your truck with a 24 volt system is compatible with 12 volt electric brakes, the Dexter Electric Trailer Brake Kit - 12" - Left and Right Hand Assemblies - 7,000 lbs # 23-180-181.

  • Is Using Electric Brakes on a Boat Trailer Recommended
    You can indeed use electric brakes on a boat trailer. At one time it wasn't a recommended practice, but then the boat manufacturers started using electric brakes on trailers and found that it works fine. I would urge you to unplug the trailer before backing it into the water, and when pulling out allowing a few minutes to drain and dry out somewhat before plugging back in.

  • Comparison of Quality and Weight Rating- etrailer Brand Versus Dexter Brand 12 x 2 Brake Assemblies
    Great question. The etrailer brand # AKEBRK-6 12x2 inch brake assemblies are designed for 5200-7000 lb axles, are manufactured overseas and would work perfectly well for your tandem 7K axle trailer. Dexter, on the other hand makes specific brake assemblies for a 5.2K, a 6K or a 7K axle. The brake assemblies are manufactured in the US and as expected, the quality would be a little better but that additional quality comes at an increased cost. For a 7K axle, you'd use # 23-180-181.
