    • Less chance of cracking and crumbling that can lead to mechanical lockup, thanks to tapered edge and circular grinding
  • Self-adjusting brakes do not require periodic manual adjustment like standard brakes
    • Fine-tooth brake adjustment gears allow for a more precise setting
  • Dust shields protect from debris while you're towing
  • E-coated backing plates resist wear and corrosion
  • Adjuster plugs (included) cover access holes to keep dirt and grime out of the assemblies and off of the shoes
  • Left-hand (driver's-side) brake assembly and right-hand (passenger's-side) brake assembly included
    • Mounting bolts and hardware (BRKH122510) sold separately

Self-Adjusting Brakes Don't Require Routine Adjustment

Standard electric brake assemblies require manual adjustment of the brake shoes over time to provide longer-lasting and more efficient braking performance. With self-adjusting brakes, the brake shoes are always properly aligned, so there's no need to manually adjust the brakes after the initial adjustment. As a result, you get optimum performance without having to take the time to continually perform this type of maintenance.

Thoroughly Tested for Safety

These brake assemblies meet the requirements for certification by the Canadian Standards Association (CSA). The CSA creates standards, which when complied with ensure a safe and quality product. These brake assemblies underwent extensive testing to measure stopping distances when braking. These brakes have also been tested by QAI for braking performance in a complete automotive setup and under real-world conditions to provide the most realistic scenario for the everyday driver.

Automotive-Grade Friction Material

Each shoe on these brake assemblies is lined with automotive-grade friction material for improved stopping performance and longevity. The friction material is fully bonded onto the surface of the brake shoe. This lining is custom-molded for a perfect fit. The edges are tapered to ensure long-lasting performance. This taper, along with the circular grinding that the lining undergoes, helps to prevent cracking and crumbling. This durability helps to prevent mechanical lockup, which can occur when brake shoes are excessively worn or broken.

The friction material is also SAE-N certified, which means that it is an environmentally safe product that complies with California and Washington regulations regarding the composition of brake pads. As a result, this material not only provides high-performance braking that can endure the test of time, but it is also environmentally friendly and safe for use throughout the United States and Canada.

  • Trouble Removing Spindle Nut On Dexter 10K Axle
    Thank you for your purchase of the Electric Trailer Brake Kit w/ Dust Shields part # AKEBRK-10. In some cases, you can remove the spindle nut with a set of channel locks but in others you will need to use a socket and ratchet or even possible a breaker bar depending on how long the spindle nut has been on there. If you have access to a torch you can heat the nut up as that will help to remove it but otherwise you just need to use more force. For a new tang washer you can use part # 5-59.

  • Replacement 12-1/4 Inch x 3-3/8 Inch Braking Assembly with Four Bolt Brake Mounting Flange
    If the braking assemblies you have now are indeed 12-1/4" x 3-3/8" and use a four bolt brake mounting flange then you are going to want to use the Electric Trailer Brake Kit w/ Dust Shields part # AKEBRK-8, not the Electric Trailer Brake Kit w/ Dust Shields part # AKEBRK-10. I have attached a photo which shows the correct way to measure your braking assembles for replacement. You will also need to verify that the bolt holes on your brake mounting flange are 3-7/16" apart on center from...

  • Will etrailer Self-Adjusting Electric Trailer Brake Kit for 10,000 lb Axle Work on Dexter Hubs
    Yes, the self-adjusting Electric Trailer Brake Kit w/ Dust Shields # AKEBRK-10 will work on Dexter Axle hub and drums, so long as you have the appropriate 7-bolt brake mounting flange. These brake assemblies are rated for 10,000 lb axles and only require the Mounting Hardware # BRKH122510 to install. I've added a link to a video review for you to check out as well.

  • Will etrailer.com 12-1/4 inch by 3-3/8 inch Brake Assemblies Replace Dexter Brand
    For your Dexter drums that take assemblies that are 12-1/4 inch by 3-3/8 inch our etrailer.com brand asssembly set part # AKEBRK-10 is a confirmed fit and will save you money over the Dexter kit # 23-450-451. These are both kits for 10k axles. If instead you have 8k you'd need # AKEBRK-8 for etrailer.com brand and # 23-434-435 for Dexter.

  • Individual Assemblies that Come with Electric Trailer Brake Kit # AKEBRK-10
    Yes, the left and right hand assemblies of the kit part number # AKEBRK-10 are available as part numbers # AKEBRK-10R for the right hand side and part # AKEBRK-10L for the left hand side. The kit does not include anything beyond just the two assemblies so if you happen to catch our pricing algorithm offering them individually at a better price that's what I would recommend you go with!

  • Availability of Electric 6 Bolt Mount Brake Assemblies for 10K Axle
    Unfortunately, we don't offer any 6 bolt brake assemblies all the brake assemblies we offer for a 10K axle use a 5 or a 7 bolt mounting flange. According to Dexter, they discontinued those brake assemblies about 20 years ago. The good news is that spare parts are still available. To identify the correct parts, we'll need to know if you have the general or heavy duty brake assemblies. Just measure the existing brake shoes, if they're 3-3/8 inches wide they're general duty, if they're...

  • Does Brake Width Matter for Brake Assemblies on a 10K Trailer Axle
    The closest brake assemblies that we have to your 12-1/2" x 3-1/2" measurements come in the Brake Kit # 10257-59 and are 12-1/4" x 3-1/2". The most common measurements for a 10K axle (which from your measurements sounds like you have) are 12-1/4" x 3-3/8" which are found in the Brake Kit # AKEBRK-10 that you referenced. The 12-1/2" diameter measurement that you took is a bit unusual and I couldn't find anything that matches. If you measured your hub and drum assembly then it is possible...

  • Electric Drum Brake and Hub/Drum for 10K Axle
    I linked our main page for all electric drum brakes rated for a 10K axle. These are all 12-1/4-inch diameter but vary in width; 3-1/2-, 3-3/8- and 4-inch widths are available. We have these in both manual-adjust and self-adjust types. For example, part # AKEBRK-10 is a high-value pair of self-adjusting left- and right-hand brakes in the 12-1/4 x 3-3/8 inch size which fits wheels 15-inches in diameter and larger. These brakes use a 7-bolt mounting pattern. We do offer a 10K oil bath...

  • Converting Drum Brakes On A Dexter Military Trailer Axle With 8 On 6-1/2
    I would be happy to help you choose the correct brake setup for your Dexter Torflex Axle, however there are no manufacturers that currently make electric disc brakes. All disc brakes are powered by a hydraulic cylinder. If you wish to use a disc brake setup controlled by an in-cab brake controller, you will want to consider the HydraStar Electric Over Hydraulic Actuator for Disc Brakes part # HBA16 and an electric brake controller such as the Tekonsha Prodigy P3 Trailer Brake Controller...

  • Brake Assembly Recommendation for BigTex 20ac With 10k Axles
    The brake assembly set you need for each of your 10k Dexter axles is the part # 23-450-451. This set of left and right assemblies is exactly what your Dexter axles need and they are self adjusting as well.

  • Where To Start for Adding Electric Brakes to a Trailer
    Sounds like you are trying to add trailer brakes to a trailer that currently does not have any installed. I attached a help article that will walk you through the entire process, but basically you will need to first determine what spindle you have on your trailer axles so that you can find the right hub/drum to fit the axles. Once you have that figured out you will be able to piece the rest of the parts needed from there. I also attached a picture that shows what info is needed to identify...

  • What Bearings and Grease Seals Does a 10,000 Lb Trailer Axle Use
    If you have a standard 10,000 lb trailer axle then you will need to use a 387A (2.250") inner bearing, 25580 (1.750") outer bearing, and a 10-51 (2.875") grease seal like what is included with the Dexter Trailer Hub and Drum Assembly part # 8-430-5UC3. However, not all 10,000 lb trailer axles use the same bearings and seals therefore you will be wise to measure the spindle where the bearings and seals ride with a digital caliper like part # 301-17068 beforehand.

  • Brake Assembly for Dexter 10k Axle with 12 1/4 x 4 Brakes
    I have a solution for you but part # AKEBRK-10 is not what you are looking for. Instead the Dexter Electric Trailer Brake Kit Left/Right Hand Assemblies part # 23-438-439 is the set you need. The others are just a little too narrow for your application.

  • Is the Electric Trailer Brake Kit for 10K Axles Sold As a Pair
    The Electric Trailer Brake Kit part # AKEBRK-10 is sold as a pair, so one left and one right. This kit would be sufficient for one axle which is another way of looking at it. If you need new mounting hardware which I do recommend replacing we have this as well, the Mounting Bolts and Hardware for 12-1/4" Brake Assemblies part # BRKH122510 which is again for a pair, therefore one axle.

  • Inner Brake Drum Dimension of Dexter Drum 009-044-01 to Brake Dust Shield Mounting Flange
    I went out to our warehouse to measure the Dexter Trailer Brake Drum # 9-44-1 drum for you. From the inside wall to the inside lip the measurement is 4-1/2 inches where it will come to the dust shield of the brake assembly where it mounts to the axle flange. The brake assembly I recommend for that hub is the Electric Trailer Brake Kit w/ Dust Shields - Self-Adjusting - 12-1/4" - Left/Right Hand - 10K # AKEBRK-10.

  • Replacement Brake Magnets for Kauffman Trailer with 10k Lippert Axles
    The size brake assembly you mentioned of 12-1/4 inch by 3-1/8 inch is not a standard size for a 10k Lippert axle but it's pretty close to standard sizes in width. The diameter of 12-1/4 inch is fine but the widths typically are 3-1/2 inch or 3-3/8 inch. What it looks like you have is the AxleTek or etrailer.com assemblies part # AKEBRK-10 based on the picture you submitted. Which for that you could use the magnet part # BP01-301 for.

  • Replacement Self-Adjusting 12-1/4 x 3-3/8-Inch Electric Drum Trailer Brakes to Replace 023-451-00
    Brake part 023-451-00 refers to a right-hand Dexter electric drum brake for 9K and 10K-rated axles. The brake dimensions are 12-1/4-inch diameter and 3-3/8-inch width. We do offer this size of brake in 8K, 9K and 10K axle capacities in the self-adjusting variety; these are shown on the linked page. The best value among all is the 10K-rated etrailer Axle Teknology brake pair # AKEBRK-10. These drum brakes work with wheels from 15-inches up to 17-1/2-inches. These use a 7-bolt mounting...

  • Converting Hydraulic Brakes on M105a2 Military Trailer to Electric Brakes
    To get you the correct fit for your M105a2 trailer, I need to know what is currently on your trailer. We've seen a wide variety of axle capacities from 5,200 lbs to 10,000 lbs. If you can help me with drum/hub dimensions, I can see what we have that may be compatible with your specific trailer. For instance, if you have 12-1/4 x 3-3/8 inch drums, then the Electric Trailer Brake Kit w/ Dust Shields - Self-Adjusting - 12-1/4" - Left/Right Hand - 10K # AKEBRK-10 would be a great option....

  • Recommended Brake Assemblies for 31 Foot Travel Trailer with Tandem Axles
    For axles that are roughly 5,000 lbs each base on your 10,000 lb rating, you will need 12 inch brake assemblies for your 31 foot travel trailer. I recommend the Electric Trailer Brake Kit - Self-Adjusting - 12" # AKEBRK-7-SA. If you have hydraulic brakes, you will want # AKFBBRK-7 instead which is a free-backing brake assembly. These assemblies both work with the standard 5 bolt mounting flange on axles of this capacity level. If you meant that each axle was rated for 10,000 lbs,...
