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.


A trailer drum brake with a red callout shows the location of a tension cable and pulley on a self-adjusting trailer brake.

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:

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.

It took awhile to get the correct part numbers, but when done, the product installed nicely! Highly recommended.

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.

  • 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.

  • Availability of 10 inch Brake Assemblies with 4.4k Capacity by Dexter
    We 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.

  • What Brake Assemblies for 4400 Lb Axles
    A 12 inch 5200 lb rated brake assembly isn't compatible with the 10 inch hub used by a 4400 lb axle, but we do indeed offer 4400 lb brake assemblies, as part # K23-462-463-00 for standard brakes or for self adjusting brakes (which I'd recommend), use part # K23-478-479. Either set of brake assemblies would be compatible with the brake drums used on your 4400 lb axles. Either set of brake assemblies mentioned above include the adjuster hole covers and mounting hardware.

  • Which Replacement Hub/Drums for 4.4K Dexter Torsion Axle
    The 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,...

  • Brake Assemblies for Rockwood Signature Ultra Lite 5th Wheel with ALKO 4K Torsion Axles
    Based on my research, it looks like your 2006 Rockwood Signature Ultra Lite camper has a tandem axle setup and the axles are 4,000 lb AL-KO torsion axles.There should be a label on the axle listing the manufacturer and the weight rating of the axle so that you can confirm these are the axles on your trailer. From there we will want to measure the brake assembly's mounting flange to make sure we get the correct replacement assemblies. We'll need to measure the top bolts center to center,...

  • 10" Electric Trailer Brake Assemblies For 4,400LB Axles With 3-1/4" Lower Bolts and 2-7/8" Top Bolts
    The Dexter Electric Trailer Brake Kit # K23-462-463-00 and Dexter Nev-R-Adjust Electric Trailer Brake Kit # K23-478-479 for 4,400LB axles have a similar bolt pattern. They have 2-7/8" measured on the top 2 bolts and 3-1/4" spread on the bottom 2 bolts, so either the numbers got entered in the wrong order or someone may have flipped the axle rather than using the proper Dexter Trailer Springs Over-Under Conversion Kit # K71-384-00. The brakes are still the 10" diameter by 2-1/4" wide.

  • How to Determine Correct Capacity When Choosing Electric Brake Assemblies
    As you mentioned in your question, the 3,500 pound and 4,400 pound electric brake assemblies we have available both feature the same 10 inch x 2-1/4 inch measurement. When determining which rating is correct for your trailer, you will need to locate the capacity of your axle(s). This information should be printed on a tag/sticker somewhere on the axle itself, or listed somewhere on the trailer frame. It is more likely that you have a 3,500 pound axle, as this is simply a much more common...

  • Best Brake Assembly Setup for Trailer with 4,400 lb Axles
    For a set of brake assemblies that are a fit for the 4,400 lb axles you have on your trailer the part # K23-478-479 would be the best option. You'd need to verify the bolt pattern of the mounting flanges though. See picture. These are Dexter and they are self adjusting which means you'll never have to mess with adjusting assemblies. Also make sure the trailer is using 10 gauge wire for all of the brake controller wiring like our part # 10-1-1 which we offer by the foot.

    The Dexter Nev-R-Adjust Electric Trailer Brake Kit # K23-478-479 are 10" diameter brakes for a 4,400lb axle that uses 4 bolts to mount to the axle. These brakes do have a unique mounting pattern of 2-7/8" bolt center spread on the top mounting bolts, and 3-1/4" bolt center spread on the bottom bolts.

  • Replacement Brake Assemblies and Grease Seals for Dexter 4400 lb Trailer Axle
    I'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...

  • Replacement Brakes for Tandem Axle Trailer With Brake Backing Plate Welded On
    It 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...

  • How to Determine if Dexter Brake Assembly is Manual or Self-Adjusting
    If you have a self-adjusting brake assembly, you'll be able to see the adjuster cable extending across the brake assembly once you remove the hub/drum. However, we sell the Dexter brake kit # K23-463-00, so we can confirm the brakes are not self-adjusting. If you would like to install self-adjusting brakes, you'll have to adjust them once during the initial install, but after that, they will self-adjust.

These are sold as a pair so that you can replace both seals on one of your axles so you will need 2 kits to replace all 4 seals. The Seal Puller # PTW1219 will help you remove the old seals without risking damage to the bearings.

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.
