Great price and quick delivery. The local RV service center did not carry the Dexter electric brake assembly and could not fix my trailer brake quickly enough because they were booked for a month. I was able to replace the brake myself with the unit I got from etrailer. It was easy to install since it comes preassembled and ready to mount. There are a number of online videos available showing how to connect the wires and the proper way to mount the brakes. 851092

The whole experience of ordering my replacement brake assemblies was awesome. Teresa did a fantastic job of figuring out which parts I needed. I would not hesitate to order parts from e-trailer in the future. The quality and fit-up of the Dexter brake assemblies made repairing my rv easier than I could have imagined. I am one happy camper. Thank you for an awesome consumer experience from start to finish. 634446

Although I have yet to install them, the products look good and I am pleased with everything so far except at the initiation of the order. After I placed the order online I never received a confirmation or tracking number. I called etrailer two days later and the order hadn't been processed. Everything was in stock so the order was then processed but did not ship until a day later. Processing and more timely shipping would be very much appreciated in the future. Thank you. 396181

Review from a similar Nev-R-Adjust in Accessories and Parts


Item: 23-458: This item Is a replacement for my 5th wheel camper. Do to the fact while traveling the brake did not release and failed on interstate I-40 late in the evening.The heat caused all the parts on the spindle to fail. The cost of replacing brakes, drum, bearing, seals, grease, plus service cost is Very Expensive after hours. Having these items on hand can save a lot of time and money. Etrailer parts are top quality and best online price. Thanks 321760

I have been buying various products from etrailer.com for many years, and they always go out of their way to make the process as pleasant and simple as possible. I ordered the Dexter Nev-R-Adjust Electric Trailer Brake Kit late Thursday afternoon, and it was delivered to me by noon the following Monday. Prices at etrailer.com are always good, and free shipping on orders over $99 makes them even better. I also appreciate all the help etrailer provides with their how-to videos. I'll be buying all my future trailer parts from them. 582264

I ordered 2 sets of 10" 2 1/4 electric shoes / self adjusting for my Jayco eagle. Received them about 5 days after i ordered them. have installed all but 1 on rear axle. They were very easy to install and wire. tested them today while burnishing them going to another park so far they work well. hope to finish the last on soon. I did replace all bearings and seals on each wheel as i was changing them out. 704217

So wonderful to have brakes automatically adjusted instead of doing it manually and wondering if all four wheels have equal braking. I know what happens when one brakes more than the others: over-heating and failed wheel bearings. Not fun. 663205

Replaced the Axel Teknology made in China brakes that failed due to poor grease seals with Dexter brand made in USA. All parts made in a ISO 9001 facility. MAGA! New brakes perform great. 553826

Brakes are working great and should for a long time. See more trailer manufacturers are using Dexter now. Buy products made in the USA!

Review from a similar Nev-R-Adjust in Accessories and Parts


I recently completed a brake upgrade on my trailer. The new Never Adjust Dexter Brakes went on flawlessly. I found the process to be straight forward. The self-adjusting feature was an upgrade from the previous brakes but bolted on with no issues. I like the idea of not needing to adjust brakes as the pads wear down. I needed all new brakes, this seemed like the best decision for replacements. 539350

  • Replacement Dexter 10 Inch Electric Brake Assemblies for Off-Road Camper
    To replace the 10 inch brake assemblies on your offroad camper I recommend the Dexter Electric Trailer Brake Kit # K23-086-087-00. This kit includes both the Left Hand and Right Hand assemblies and will work perfectly as replacements to your existing Dexter units that include the manual parking brake levers. I do agree that going with a complete replacement will be easier and likely more cost-efficient than trying to replace individual components. I have attached a short video demonstration...

  • Recommended 10-Inch Trailer Brakes With Parking Brake
    We do have electric brakes that come with the parking brake that will work for you. I recommend part # K23-086-00 for the left hand(driver side). For the passenger side you can use part # K23-087-00. The brake assembly you asked about will not work with a parking brake as you mentioned.

  • Electric Brake Assembly Compatibility with T-44 4,400 lb AL-KO Axles
    The AL-KO company was bought out by Dexter, so he may have been thinking Dexter axles which the # K23-478-00 and # K23-479-00 would fit with the 4 bolt mounting pattern. The K23-538-00 and K23-539-00 are the correct ones for the AL-KO T-44 axle, as you mentioned but they have been discontinued. The only option is to replace the axle(s). Depending on the hub face and spring center dimensions of your existing axle and wheel bolt pattern, we may have what you need. I have included a link...

  • Brake Assembly Replacement Recommendation for Dexter Assemblies 36-19-47
    Based on what you described you have a standard 4-bolt trailer brake assembly bolt pattern. For brake assemblies that match that and the 4,400 lb axle capacity you have you'd want the part # K23-478-00 for the left hand side and part # K23-479-00 for the right hand side. For a brake flange you'd then want the part # 4-35 if you were also in need of that.

  • Torque Specs of Mounting Flange Bolts on Dexter Nev-R-Adjust Electric Trailer Brakes
    I spoke with a representative of Dexter who told me that the 4 mounting flange bolts on the Dexter Nev-R-Adjust Electric Trailer Brake Assembly # K23-478-00 (left hand) and # K23-479-00 (right hand) who was unable to confirm the specific torque specs of these assemblies. However, based on similar assemblies from Dexter we do know that in the past the recommended torque is between 45-70 foot lbs.

  • Brake Assembly Recommendation for a Dexter 4,400 lb Axle with 10 inch Assemblies
    By the time you add up the cost to replace the magnets and shoes on your trailer you are at the cost (or more) for all new assemblies plus you end up saving yourself the trouble of messing with trying to install all the components. For an exact replacement for the assemblies of your trailer you would want the part # K23-478-00 for the left hand side and part # K23-479-00 for the right hand side. Replacement parts for these assemblies are even harder to find than normal assemblies...

  • Nev-R-Adjust Brake Assemblies for a 4400 lb Dexter Axle
    There are a few differences between the Dexter 3,500 lb brake assemblies and the 4,400 lb brake assemblies including the brake shoes, magnets, adjusters and adjuster springs. Because the 4,400 lb brake assemblies must be able to provide more stopping power than the 3,500 lb brake assemblies they will have upgraded components. The 4,400 lb brake assemblies also have a different bolt hole pattern on the backing plate to mount to the brake mounting flange on the axle than the 3,500 lb...

  • Brake Assembly Replacement Recommendation for Trailer with Lippert 4,400 lb Axles
    The brake assemblies you'd need are the part # K23-479-00 for the right hand side and part # K23-478-00 for the left hand side. These are self-adjusting brake assemblies that are designed for a 4,400 lb Lippert axle like you have.

  • Brake Assembly Recommendation for a 2004 Keystone Cougar 285 Camper Trailer
    I did some research on your 2004 Keystone Cougar and it looks like it's a tandem axle trailer with a dry weight of 7,340 lbs. Keystone almost always uses Dexter axles so the correct brake assemblies should be 4,400 lb rated 10 x 2-1/4 inch brake assemblies like the part # K23-478-00 for the left hand side and part # K23-479-00 for the right hand side. Or if you measure the diameter of your assemblies and they are 12 inches you would instead need the part # 23-459 for the right hand side...

  • Replacement Brakes, Bearings & Seals for AL-KO 4400-lb Axles on 5-Year-Old Tandem Axle RV
    The # K23-478-00 and # K23-479-00 Dexter brake assemblies you mentioned are not compatible with your AL-KO T-44 axle. According to my contact at Dexter (AL-KO was acquired by them), the replacement brake assemblies for your AL-KO axle are now obsolete as they have been discontinued. The only option is to replace the axles on your RV. Since we don't carry any 4,400 lb axles, the closest rated axle we have (that would also match the 6 on 5-1/2 wheel bolt pattern found on the T-44 hubs)...

  • Can Electric Trailer Brakes for a 4,400 Pound Axle be Used in Place of Brakes for a 3,500 Pound Axle
    Electric trailer brake assemblies for both 3,500 pound and 4,400 pound axles are 10 x 2-1/4 inches and both have the 4 hole square mounting pattern. So you can use 4,400 pound axles brakes. For the left use # K23-478-00 and for the right use # K23-479-00. These are Nev-R-Adjust assemblies which means after you adjust them the first time you will not have to manually adjust them again.

    When it comes to 10 x 2-1/4 inch brake assemblies there are a few things you need to consider before purchasing. The first you will need to know is if you have electric or hydraulic brakes on your trailer. There is also a difference in the weight capacity of the axles the will fit. There are 3,500 lbs and 4,400 lbs axles ratings. However, the 3,500 lbs and electric brakes are the most common size. After these two factors are determined, then the rest is a personal preferences.The...

  • Cushioned Equalizer Fit for 2015 Prime Time Lacrosse 318BHS
    Looks like you have a longer equalizer setup on your 2015 Prime Time Lacrosse 318BHS but I would need the length of the equalizer to ensure we get you the correct replacement. We do have the Equa-Flex Cushioned Equalizers # LC314336 which appears to be what you are in need of. It measures 14-5/8 inches from the side holes and then 3-1/4 inches vertically so you'd need to measure yours to compare. This is a cushioned equalizer setup that will smooth out the ride quality of the trailer.

  • Brake Assembly Replacement Recommendation for K71-125-00
    For an exact replacement for the assemblies of your trailer you would want the part # K23-478-00 for the left hand side and part # K23-479-00 for the right hand side. Brake assemblies are not what you'll use to make your braking more aggresive. For that you'd want to increase the gain setting of your brake controller as that's how you adjust the braking power higher.

  • Replacement Brake Assembly Recommendation for Dexter 23-479
    The assembly you have is our part # K23-479-00. For shoes you'd want the part # K71-699-00. We don't have the magnets for those hubs though. But if the assembly is bad enough to need shoes and magnets you are better off just replacing the whole thing. The price is about the same and you'll end up with new everything and the install will be much easier.

These brakes automatically adjust as the brake pads wear so you do not have to manually adjust the brakes. I have attached a review video of these brakes for you.

  • Do I Have to Replace My Dexter Brakes With Dexter Brakes
    If you really liked the Dexter brakes and want to continue to use that brand I can help you find exactly what you are looking for. Otherwise, no, you do not have to replace the electric brakes on your trailer with the same Dexter brand. The Nev-R-Adjust Electric Brake Assemblies, part # K23-478-00 LH (driver side) and part # K23-479-00 RH (passenger side), from Dexter that you referenced are great options since you do not have to keep adjusting the brakes.

    There is no difference between buying the brake assemblies individually or as a kit with the Dexter Nev-R-Adjust Electric Trailer Brake Kit - Left and Right Hand Assemblies # K23-478-479. Prices have to do with things like demand, and some people only need individual assemblies, so the prices can be different because technically they are different part numbers. But to get to the heart of your question, you can absolutely order the brakes individually and there is no difference. -...

Since there is a very good chance that it has the 10 inch x 2-1/4 inch brake assemblies, you could use the Dexter Nev-R-Adjust Electric Brake Assemblies, # K23-478-00 for left hand and # K23-479-00 for right hand.

  • Parts Needed to Replace Hydraulic Drum Trailer Brakes with Electric Drum Trailer Brakes
    The 10x2-3/4 measurement on brakes is in reference to what drums they fit, not the mounting pattern. The 2-3/4 inch measurement you are getting is indicative of 10x2-1/4 inch brakes like # K23-478-00 that you have referenced. To measure for the size brake assembly you need you will measure the inner diameter of the drum and the width (both where the shoes/linings make contact with the drum). The matching right hand side brake assembly is # K23-479-00. But if you have 3,500 pound axles...
