Quick Tip: There's really not a whole lot to getting new drum brakes. If you've confirmed that all of the specs listed above line up with what you need for your trailer, you can be pretty sure these will work for you.
Self-Adjusting Brakes Don't Require Routine Maintenance
With standard electric brake assemblies, you need to manually adjust them every now and then to make sure you're getting the shortest stopping distance every time you tow.
With self-adjusting brakes, though, you'll always have peak stopping power - simple as that! As the brake pads wear over time, a tensioning cable will automatically keep the pads in alignment so they'll consistently make contact with your drum when you brake. You won't have to do tedious manual adjustments anymore.
Thoroughly Tested for Safety
Dexter invests a lot of resources to ensure that these brakes meet the requirements for certification set by the Canadian Standards Association (CSA). Basically, a CSA certification tells you that these trailer brakes are well built and safe for use on the road.
How to Break In New Brakes
Once you get these brakes installed, you'll need to break them in. First, find a long stretch of road or a big, empty parking lot. Once you're there, set your brake controller to its maximum setting and get moving. Speed up to about 40 mph and brake to slow to about 20 mph. Repeat this 15-30 times. The goal is to get the brake shoes and magnet properly seated into your drum. You'll know you've done that when it feels less jerky (and more consistent) each time you apply the brakes.
Note: The brakes will be very hot after doing this, so after every 10 stops you'll want to wait about 10 minutes to let the brakes cool off before continuing. If you don't, you might cook and crack the pad material.

After doing my homework on what I needed for my Grand Design 230 RL finding the original equiptment replacement parts was essential. After much time on the internet E Trailer had what I needed. I was taken back by the pricing after my search showed some less expensive replacements of the not OE quality. Upon receipt of my purchase I see why the price. Very high quality. Happy me.
by: Larry 03/28/2024
Easy to install and have been good reliable brakes for several trips so far. Although, extremely expensive. At over 3 times the cost of the next size down, seemed excessive, but if that’s the size you need you have no choice.

Great service. Got everything fast and complete. Great product and service.

My order was taken courtesly, delivered on time and received as ordered! The Dexter brake assembly was the correct match and installed with minimal effort. I haven't pulled the 5th wheel yet so can't comment on practical use but dealing with etrailer has been seamless. Thanks.

The parts received were the correct ones. After trying to find them locally and being sold the incorrect parts and then after several days being told they were unavailable, it was a relief to easily find, order and receive the corect parts. Thank you etrailer!

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.

I was in trouble time wise to get my trail brakes fixed. I called Montrell at etrailer...He was extremely helpful to quickly process my order. The brakes came before the time quoted, and they were put on and done quickly. I will always start with etrailer when I need products that you have. Thanks to your company and Montrell.

Easy to install. Exactly what I needed for my camper. I called a local camper dealer to inquire about buying them and was told “we do not do brakes”!
So I called you and you fixed me up immediately....Thank you!

- Is There a Difference Between Brake Assembly Kit and Individual Brake Assemblies for 4,400 lb AxleThere 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. - Dexter...
view full answer... - Correct Replacement Brakes and Hubs/Drums for Open Range Roamer 316RLSThe correct hub/drum for a Dexter 4,400 Lb Axle is the Trailer Hub and Drum Assembly part # 8-407-5UC3-EZ and then for the brakes you can use the Dexter Nev-R-Adjust Electric Trailer Brake Kit part # K23-478-479.
view full answer... - Are the Dexter Nev-R-Adjust Electric Brake Kits Sold As Pairs The Dexter Nev-R-Adjust Electric Trailer Brake Kit - 10" - Left and Right Hand Assemblies - 4.4K # K23-478-479 are sold as a pair (left and right brake assembly) for one axle. If you've got a tandem axle trailer you'll want to order two sets of these. These brake assemblies do not include mounting hardware so if you need to replace yours then you'll want to use the Mounting Hardware for 10" Brake Assemblies # BRKH10B as well, for each axle you're replacing the brakes on.
view full answer... - How Many Axles Does Dexter Nev-R-Adjust Assembly Set # K23-478-479 ReplaceThe Dexter brake assembly set part # K23-478-479 comes with a left and a right assembly for a single axle. Since you have a tandem axle trailer you'd need to order a quantity of 2 of these.
view full answer... - Replacement Brake Kit for 2012 Jayco Jay Flight 32BDHSFrom what I could find it looks like the GVWR of your 2012 Jayco Jay Flight 32BDHS is 10,200 lbs. This means that you likely have 12" brakes so the correct self-adjusting electric brake kit is part # AKEBRK-7-SA. You will want to verify this on your end though just to be sure. If you find a different diameter then it is likely the smaller 10" Nev-R-Adjust Kit # K23-478-479 instead.

To replace your existing brakes with self adjusting brakes I recommend the Dexter Nev-R-Adjust Electric Trailer Brake Kit - 10" - Left and Right Hand Assemblies - 4.4K, Item # K23-478-479. This kit fits 13-inch to 15-inch wheels and includes both the driver's-side and passenger's-side brake assemblies, adjuster plugs, mounting bolts, and nuts. The lockwashers...

- Replacement Brake Assembly and Grease Seal for AL-KO T44 AxleFor your AL-KO T44 axles, the brake assemblies you need are the Dexter Nev-R-Adjust Electric Trailer Brake Kit - 10" - Left and Right Hand Assemblies - 4.4K # K23-478-479 or the manual adjust # K23-462-463-00 along with spoon adjuster # W80630. The grease seal you want is AL-KO part 568861 which is the Grease Seal - Double Lip - ID 1.719" / OD 2.565" # RG06-050 for a set of 2 seals.

- Self Adjusting Brake Assembly Recommendation for Dexter 4,400 lb Trailer AxlesWe have just what you need. The # K23-478-479 is a set of Dexter brake assemblies for 4,400 lb axles that are self adjusting. You'll just need to pull off your hubs and install these in place of them and you'll be set.
view full answer... - Correct Replacement Brakes and Hubs/Drums for 2012 Dutchmen Classic 276RBSThe correct braking assemblies will be the Dexter Nev-R-Adjust Electric Trailer Brake Kit part # K23-478-479 and the correct hubs/drums will be the Dexter Trailer Hub and Drum Assembly part # 84656UC3-EZ. I called Lippert and confirmed these as fits for a 2012 Dutchmen Classic 276RBS.
view full answer... - Which Replacement Hub/Drums for 4.4K Dexter Torsion AxleThe 4.4K axle uses a fairly unique bearing set, so you'll want to check the reference numbers on your inner and outer wheel bearings to ensure the replacement hub uses the same wheel bearings. If your current hubs use a LM67048 inner and a L44649 outer bearing (which they should), then the correct replacement hub drum is part # 8-407-5UC3-EZ. The hubs have a 6 lug on 5-1/2 inch bolt pattern and are sold individually. The hub includes the inner and outer bearing, the races which are pre-installed,...
view full answer... - Electric Brakes That can be Used With a 4,000 lb AxleIf you were using the search filters and only came up with the lowest axle rating of 5,200 lbs that probably means your drum or wheels are too big for the assemblies that we carry. For any of our assemblies you would need to have a 4-bolt flange mounting pattern, drum size of 10" diameter x 2-1/4" wide and wheel sizes from 13" to 15". If so, you would be able to use electric brake assemblies for a 4,400 lb axle such as the Dexter Nev-R-Adjust Electric Trailer Brake Kit # K23-478-479....
view full answer... - Replacement Brakes for Tandem Axle Trailer With Brake Backing Plate Welded OnIt sounds like you have mobile home axles on your trailer. You will not be able to add parts from other brakes to the welded on backing plate and there is no kit to restore them so your only option would be to cut those off. More than likely with a 10" drum and 10" brakes you have a 3,500 lb axle with a 2-3/8" diameter. Assuming that is the case, you would need to weld on a flange like the Brake Mounting Flange for 2-3/8" Round Axle # 4-35. The brake mounting flange needs to be welded...
view full answer... - Replacement Brake Pads for 4,400 lb Nev-R-Adjust Dexter Axle Electric BrakesTo replace just the brake pads that come on the Dexter Nev-R-Adjust Electric Trailer Brake Kit - 10" - Left and Right Hand Assemblies - 4,400 lbs # K23-478-479 you need the Replacement 10" x 2-1/4" Kit # K71-698-00 for the left-hand side and Kit # K71-699-00 for the right-hand side. I confirmed this with my contact at Dexter Axle Attached is a review video for you to check out.
view full answer... - Replacement Brake Drum Hub Assembly For Dexter D44 4,400LB AxleYour Dexter D44 Axle number 635096 uses the Trailer Hub and Drum Assembly # 8-407-5UC3-EZ that comes preloaded with the Races # LM67010 and # L68111. It does include the Bearings # L68149 and # LM67048, Grease Seal # 58846, Grease Cap # 21-42-1 and lug nuts. The Brake Assemblies # K23-462-463-00 that came with your axle can be upgraded to the Dexter Nev-R-Adjust Electric Trailer Brake Kit # K23-478-479 to reduce the maintenance as well as improve braking and extend the life of your brake...

- Availability of 10 inch Brake Assemblies with 4.4k Capacity by DexterWe do have the Dexter 10 inch brake assemblies you are looking for. For that the part # K23-478-479 would be what you'd want. This is a 10 inch Dexter brake assembly pair with a 4.4k capacity just like what you need. This comes with an assembly for either side of the trailer.
view full answer... - Replacement 10 x 1-1/2 Electric Brake AssembliesI have a solution for you, but we do not have a self adjusting brake assembly like the # K23-478-479 available in a 10" x 1-1/2" brake. Instead, you can use the Dexter Electric Trailer Brake Kit - 10" - Left and Right Hand Assemblies - 3,000 lbs # K23-472-473-00, which is 1-1/2" wide and mounts to a 4 bolt flange. These assemblies don't come with mounting hardware included, but you can use the # BRKH10B to replace your old mounting hardware.
view full answer... - Replacement Brake Assemblies and Grease Seals for Dexter 4400 lb Trailer AxleI'm assuming the hubs are used on a 5th wheel, is that correct? For a tandem axle setup, the combined axle capacity would be 8800 lbs. The remainder is carried by the rear axle of the tow vehicle, since the pin weight of a 5th wheel is typically 20% of the GVWR, the axles are properly rated for your RV. For replacement brake assemblies, I'd recommend the # K23-478-479 from Dexter, which includes right and left auto adjusting brake assemblies. After the initial setup, the brakes will constantly...
view full answer... - 4,400 lb Self-Adjusting Brakes for Fifth Wheel TrailerThank you for the photos, though there is only one measurement there so it would be very difficult for me to tell you exactly what you currently have. That said, the most important measurement you can take is of your brake mounting flange, and I would be very surprised if the Dexter Nev-R-Adjust Electric Trailer Brake Kit - 10" - Left and Right Hand Assemblies - 4.4K # K23-478-479 don't work for you. The bolt hole measurements of these brakes need to match up with your brake mounting flange,...

- Can Self Adjusting Trailer Brake Assemblies be Manually AdjustedYes, you can manually adjust self-adjusting brakes with a spoon like the drum brake spoon # W80630. We've done it here in the office years ago because we weren't sure if it was possible but it is. It is harder to get to the star wheel that adjusts the brake on self adjusting assemblies but it is possible. You'll need to remove the plugs on the back of the assemblies. For replacement assemblies we do have the set you mentioned of # K23-478-479.
view full answer... - Can 4,400 lb Trailer Axle Brake Assemblies Fit 3,500 lb Axle Hub/DrumsThe bolt pattern of the 4,400 lb brake assemblies like the # K23-478-479 is different from the 3,500 lb axle brake assemblies like the # 23-468-469 that would fit so that's what you'd want to go with. I know it sounds tempting to put higher rated brake assemblies on the axle to help improve braking power but it actually doesn't work like that. The difference is higher rated assemblies have a more sensitive brake magnet which only means that dialing in the correct braking power on a lighter...
view full answer... - Replacement Magnets for 10 x 2-1/4" Brakes for 4,400 Pound AxleThe magnets on the Dexter Electric Trailer Brake Kit - 10" - Left and Right Hand Assemblies - 4,400 lbs # K23-462-463-00 will be rated for 4,400 lbs. The magnets will have the same rating as the brake assembly. I am assuming you need magnets for 10 x 2-1/4" brakes. According to Dexter, the replacement magnet for the # K23-462-463-00 is the # BP01-225 Trailer Brake Magnet for 12" Dexter, 7K. These are the official replacement part for this brake assembly. I have attached a review of the...
view full answer... - New Hubs And Drums For 2008 Metalcraft TrailerSome drums can be used with hydraulic or electric brakes, some can not. You would want to check with the drum manufacturer unless it says it somewhere on the drum. Not all 10" drums take 2 1/14" brakes, however it is one of the more common configurations. Since your bearings do not have any numbers on them, you'll have to measure your spindle (C,D) shown in the image with a set of calipers # PTW80157. Form here you should have the dimensions needed to pick out the correct bearings for...

- Can the Dexter 4.4K Nev-R-Adjust Electric Trailer Brakes Be Purchased IndividuallyYes, the Dexter 4.4K Nev-R-Adjust Electric Trailer Brake Kit part # K23-478-479 can be broken down into the right side part # K23-479-00 and left side part # K23-478-00.
view full answer... - Replacement Bearings, Races, Seals, Brake Drums and Brake Assemblies for 4400 lb AxleThe spindles used on the 4400 axle are compatible with the # L67048 Inner bearing and # LM67010 race and the # L44649 Outer bearing and # L44610 race, along with the 10-19 grease seal, part # RG06-050. You'll want to confirm this by pulling one of the hubs to check the reference numbers off of your current bearings. For brakes, you'd need a 10 x 2-1/4 inch brake assembly. I'd recommend a Nev-r-adjust assembly, part # K23-478-479 for the right and left sides. Typically, it's recommended...
