Thanks for asking. The brakes are performing well and were a good purchase thru etrailer.com. Your reputation for quality continues to grow.

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.

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.




by:

Pam was great to work with. Ordered on Friday night they arrived on Tuesday. This may not be the cheapest way to do a break job, but it is the easiest. I went to the dexter dealer near home, they could order them, but it would be at least 4 weeks to get them, if they were in stock at the warehouse.




by:

The package containing brake assemblies for two axels was delivered on time and in good shape. The assemblies were exactly what I ordered and fit perfectly. Thank you for efficient and friendly experience!!




by:

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!

See what our Experts say about this Dexter Trailer Brakes

  • Electric Brakes That can be Used With a 4,000 lb Axle
    If 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....

  • Do Saltwater and Trailer Electric Brakes Mix Well
    Water and electricity don't really get along. That being said, we are seeing more trailer boat manufacturers install electric brakes on their trailers and it not being an issue at all. If the wiring is solid the circuits don't short out. It's also highly recommended that you disconnect the trailer wiring before backing in. Saltwater is highly corrosive. So the assemblies are going to start corroding quicker than if the trailer was being backed into freshwater. Rinsing the trailer with...

  • Recommendation to Replace Electric Brakes on Keystone Cougar Trailer with 4,400 Pound Axles
    For your Keystone Cougar Trailer equipped with 4,400 pound axles the Dexter Nev-R-Adjust Electric Trailer Brake Kit # K23-478-479 should work perfectly. These are designed for 4,400 pound axles but you will just want to make sure your existing mounting flanges feature the same 4 bolt pattern (see attached image) and your hub drums measure 10 inches x 2-1/4 inches. These particular brakes also have the Nev-R-Adjust feature which means you won't have to perform periodic manual adjustments...

    If you have a 023-478-00 braking assembly on the left side of your trailer then that means the correct Dexter Nev-R-Adjust Electric Trailer Brake Kit for you is part # K23-478-479 which comes with both the left and right side.

  • Can You Use a Brake hub Rated For 4400 lbs On A 4000 lb Axle.
    As long as your hub fits a 10-1/2 drum and the bolt size and bolt pattern to mount the hub to the axle matches, there should be no reason why the Dexter Nev-R-Adjust Electric Trailer Brake Kit - 10" - Left and Right Hand Assemblies - 4.4K Item # K23-478-479 wouldn't work.

  • How Do I Determine What Electric Brake System Works With My Trailer
    Nowadays you would be able to find the axle capacity stamped on your axles, but that was not always the case. If you are unable to find that information on your axles, you still have other options. The first thing I would do is try to determine the make and model of your trailer, since you already know the year, and contact the manufacturer. A picture of the trailer and/or a description might help determine the axle you have on your trailer. If that does not work, there is one more option,...

  • How Many Axles Does Dexter Nev-R-Adjust Assembly Set # K23-478-479 Replace
    The 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.

  • Replacement Trailer Brake Assemblies For Dexter 4,400LB Axle On Grand Design Camper
    You are going to want the Dexter Nev-R-Adjust Electric Trailer Brake Kit # K23-478-479 for your Grand Design camper with the Dexter 4,400LB axle. These brakes have the 2-7/8" mounting bolt hole centers for the top, 3-1/4" across the bottom and 3" from top to bottom. This is specific to your Dexter axle as the Lippert brakes that you were looking at only have the standard 2-7/8" for all 4 bolt holes.

  • Correct Replacement Braking Assemblies for Airstream International Signature 30
    It's likely you have a 4,400 lb axle which you can confirm by reading the sticker on the axle tag in the center of the beam. If that's the case then you will want to use the Dexter Nev-R-Adjust Electric Trailer Brake Kit part # K23-478-479. These are bolt-on assemblies which feature a simple four bolt pattern with two wire installation. They are standard 10" brakes.

  • Is There a Difference Between Brake Assembly Kit and Individual Brake Assemblies for 4,400 lb Axle
    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. - Dexter...

  • 4,400 lb Self-Adjusting Brakes for Fifth Wheel Trailer
    Thank 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,...

  • Difference Between Dexter 3500 lb and 4400 lb Brake Assemblies
    Actually, there's a little more to it than that. The magnets on the # K23-478-479 are a little different, but the primary difference is the mounting bolt pattern. On a typical 3500 lb brake assembly, the mounting studs will all be 2-7/8 inches apart on center. On the # K23-478-479 4400 lb brake assembly, the top studs are 2-7/8 inches apart, but the bottom ones are spaced a bit further apart to prevent a 3500K brake assembly from being used on a 4400K axle.

  • Can 2013 Forest River XLR 27HFS Toy Hauler W/ 4400lb Axle Use 3500lb Brake Assemblies?
    We have exactly what you are looking for! Since your 2013 Forest River XLR 27HFS toy hauler has a 4400lb axle instead of a 3500lb axle you would not want to go with 3500lb braking assemblies. The reason for this is the strength of the magnet will be less and you will have less braking power. Even though a 3500lb assembly and 4400lb assembly are the same size and could be interchanged, I recommend going with the Dexter Nev-R-Adjust Electric Trailer Brake Kit - 10" - Left and Right Hand...

  • Could Self Adjusting Dexter Trailer Brake Assemblies be Manually Adjusted
    You can manually adjust self adjusting brakes like the part # K23-478-479 that you referenced. You basically just use the access port on the back of the assembly to move the star wheel to the desired tightness. The linkage for the self-adjusting hardware will partially obstruct access but it is possible to get in there far enough to make the adjustment as I've done it before. For a brake spoon we have the part # W80630. Most likely though the one that is dragging the most is closest to...

  • Is Mounting Hardware Included with Dexter Nev-R-Adjust Electric Trailer Brake Kit # K23-478-479
    The Dexter Nev-R-Adjust Electric Trailer Brake Kit # K23-478-479 comes with 8 nuts and 4 adjuster access plugs. The studs are already attached to the brake assemblies so those are included by default. Lock washers are not provided but you can add them using # 5-8 which is sold in quantities of 1.

  • Recommended Self-Adjusting Electric Trailer Brakes For 7000lb Axle
    I would be happy to recommend the correct self adjusting electric trailer brakes for your 7000lb axle, but I recommend double checking that your drum is 10" x 2-1/4" since 7000lb axles typically have 12" brakes. I included a diagram of how to measure the diameter and depth of your drums. If you do have 10" brakes then the best option we have is the Dexter Nev-R-Adjust Electric Trailer Brake Kit - 10" - Left and Right Hand Assemblies - 4.4K # K23-478-479 which mount to a 4 bolt brake mounting...

  • New Hubs And Drums For 2008 Metalcraft Trailer
    Some 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.

    The Dexter Nev-R-Adjust Electric Trailer Brake Assembly Kit part # K23-478-479 or part # K23-478-00 for left and part # K23-479-00 for right does not come with a hub/drum. If this is needed you can use the Dexter Trailer Hub and Drum Assembly part # 84546UC3-EZ as most 4,400 b axles use 3,500 lb hubs/drums.

  • Replacement Trailer Brakes for Tandem 3,700 lb Axle Trailer
    Trailer brakes can definitely wear faster depending on the style of driving and the terrain, but that sounds like excessive wear. You should get way more than 3,000 miles out of a set of brakes. With your axles you must be using the 4,400 lb assemblies instead of the 3,500 lb assemblies. For the replacements I recommend the Dexter Nev-R-Adjust Electric Trailer Brake Kit - 10" - Left and Right Hand Assemblies - 4.4K # K23-478-479 or the manual assemblies # K23-462-463-00.
