Want brake adjustments that go like clockwork? These brakes automatically adjust as you tow so you don't have to crawl around on the ground to do it manually. 10" x 2-1/4" Assemblies fit 14" to 15" wheels. Made in the USA.

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.

Easy installation, just takes time. We just installed these on our 5th wheel camper and drove it to burnish the breaks as instructed to do. We have not driven our camper on a trip yet. We will see how that goes. Will update then.

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.

  • How to Determine Which Replacement Bearings for 1998 EZ Loader Boat Trailer
    I called up EZ Loader trailers for you, and given the age of your Sea Ray boat trailer they unfortunately didn't have any information about which specific wheel bearings it used. It's not the end of the world, though. We can still pretty easily figure out what you need. I was told your trailer has a 3700 lb capacity torsion axle, which would likely use a # L44649 outer and # L68149 inner bearing. The grease seal is most likely # 168233. You'll need to examine your existing bearings/spindle/hub...

  • Recommended Self Adjusting Brakes for Al-Ko 4,400 lb Axles
    Michael, so you are correct you do have 4,400 lb axles so you can use the Dexter Nev-R-Adjust Electric Trailer Brakes # K23-478-479 for replacements. These are self adjusting so you never need to manually adjust them, works with 14", 14 1/2", and 15" wheels, and includes both the left and right hand side. For hubs we have had customers in the past use # 8-201-5UC3, but you'll want to check your existing bearings and verify that they will work with this hub.

  • 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.

  • Does Surge Coupler Need to Be Replace if Trailer is Converted to Electric Brakes
    It isn't necessary to remove the existing hydraulic coupler, but you'll want to come up with a method to prevent the coupler from articulating. Many hydraulic couplers have a hole on either side that allows you to install a cross-bolt to prevent the movement, or you could tack weld the lockout so it stays on all the time and prevents movement. If this isn't an option, you could certainly replace the coupler using a 2 inch coupler for a 3 inch channel frame member like Demco eZ Latch, part...

  • Replacement Bearings, Races, Seals, Brake Drums and Brake Assemblies for 4400 lb Axle
    The 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...

  • Choosing the Correct 10 x 2-1/4 Inch Electric Brakes
    The brakes need to fit the axle. Or more specifically the hubs and the brake mounting flanges on the axle. One thing that may be confusing you is that brake assemblies for 4,400 pound axles and those for 3,500 pound axles are both 10 x 2-1/4 inches. The difference will be the brake mounting flange bolt hole pattern. If your axle is a indeed a 3,500 pound axle # AKEBRK-35-SA will work for you. The mounting bolts are included but you need part # BRKH10B for the nuts and lock washers. If...
