Dexter Electric Trailer Brake Assembly - 12" - Left Hand - 7,000 lbs - 23-180

Average Customer Rating:  4.9 out of 5 stars   (55 Customer Reviews)

12" x 2" Driver's-side electric trailer brake assembly fits 7,000-lb axles. Mounting flange has a 5-bolt pattern. Fits 14-1/2", 15", 16", and 16-1/2" wheels.


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!

So far so good! No problems with hanging brakes from being parked a majority of the time, on dirt, through wet and humid to freezing cold Massachusetts weather. Theyve also run through hundreds of miles of corrosive road salt. Had to make a few adjustments right out of the gate and am probably due for another after 2k or so miles, but thats normal break-in procedure. Well worth the price!

The parts I ordered were back ordered, although I was in no hurry for them. They communicated with me about alternative parts, and kept me informed about when the parts would be available. I did receive them when promised. I highly recommend etrailer.

Ordered the parts by phone. Melissa was highly knowledgeable and extremely professional. Would recommend eTrailer to anyone that needs trailer parts or trailer hitches.


I couldn't have been more excited about the service I received, after going to my local parts store I was able to service both axles with express shipping included for the price of 1 unit here. Mahalo Monroe for your excellent service.


The customer service is top notch! Helped me with multiple questions and updated me with E.T.A. and tracking # I will Definitely will buy from them again!!!

Parts came on time. Quality was fantastic. Very easy to install on horse trailer.


Quality parts, quick service. We are working on a Landoll trailer, that isn't in production anymore. I spent a day on the Internet looking for parts. Your site was the only one that had what we needed. I'm glad I found you!


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


I have received and installed four of these products on my trailer. Two lefts and two rights. I've been very pleased with the service and responses from on their products. I would recommend this this company in the future. Thank you very much.


Very disappointed in the time it took to get this product shipped out of your building.


The Brakes were the correct ones and fit perfectly on the axles. Was a ten min replacement per axle. I only had a small decal to identify the original backing plate and the sales person was able to cross reference the number to drive at this set of brakes. Was very painless. Thanks Mike


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


Parts were as described, and worked well for my application. AMAZED by the customer service at etrailer! Nicole T was very informative and my ordered was shipped out guys have won my business for sure!

I purchased theDexter 23-180 and 23-181 brake assemblies. such a easy task of installing. Quality is awsome.And you can not wire these wrong, and very fast delivery. Looking foward to continued buisness with etrailer. Thanks Paul


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


My No Adjust 12" brakes were completely shot after 3000 miles so I wanted to try the manual adjust. So far great. The fit well and were very easy to install.


Great product at a good price and easy to install!!!!
Put them on my equipment trailer and working good I would buy them again for another trailer


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

  • How Much Torque Required When Tightening Attachment Nuts on 12 x 2, 7k Replacement Brake Assemblies
    I spoke with my contact at Dexter and she informed me that you will need to tighten the attachment nuts to 30-35 ft-lb when installing 12 inch Electric Brake Assembly, part # 23-180, on your Dexter 7000 lb axles. I have attached a link below to a video of a similar brake hub being installed on a trailer that you might want to check out.

  • What is Needed To Choose Replacement Axle for Homemade Trailer
    You will need to replace the axle. I have linked you to our axle page. To determine which axle is compatible with your trailer, you will need to know the weight of the trailer, the hub face to hub face dimension and the distance between the spring seat centers and bolt pattern of the wheels. I'll link you to an FAQ that shows how to measure for bolt pattern, as well as to a diagram showing the measurements I'll need.

  • 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.

  • 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.

  • 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.

  • 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...

  • Should 7k Trailer Brake Assemblies be Used on a 6k Trailer Axle
    Dimensionally they'll fit and they will operate but you don't actually get a stronger braking action. Instead the brakes will be harder to setup and get the correct amount of braking action. The heavier duty assemblies have a magnet that's more sensitive which helps with heavier weights but when used on a lighter trailer they become harder to setup and not anymore powerful. Best option is go to with 6k brake assemblies like the part # 23-459 for the right hand side and part # 23-458 for...

  • 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 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. The advantage to the Nev-R-Adjust assemblies is that you don't have to manually adjust...

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. Also the 6,000 lb Dexter Brake assemblies fit wheel sizes...
