  • Electric brakes are easier to install and offer more user control than hydraulic brakes
    • Requires only an electric brake controller (sold separately) - no actuator or hydraulic lines necessary
  • Automotive-grade friction material is molded to brake shoes
    • Pads are fully bonded - not riveted - to shoes for long life and more braking torque
    • Less chance of cracking and crumbling that can lead to mechanical lockup, thanks to tapered edge and circular grinding
  • Self-adjusting brake does not require periodic manual adjustment like standard brakes
    • Fine-tooth brake adjustment gear allows for a more precise setting
  • Dust shield protects from debris while you're towing
  • E-coated backing plate resists wear and corrosion
  • Adjuster plugs (included) cover access holes to keep dirt and grime out of the assembly and off of the shoes
  • Mounting bolts and hardware sold separately
  • QAI and CSA certified


  • Application: most standard hub-and-drum assemblies, including Dexter and Lippert (LCI)
  • Configuration: left hand (driver's side)
  • Dimensions: 12-1/4" diameter x 3-3/8" wide
  • Mounting flange bolt pattern: 7 bolt
  • Wheel size: 15" or larger
  • Axle rating: 10,000 lbs
  • Limited 1-year warranty

Self-Adjusting Brake Doesn'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

This brake assembly meets the requirements for certification by the Canadian Standards Association (CSA). The CSA creates standards, which when complied with ensure a safe and quality product. This brake assembly underwent extensive testing to measure stopping distances when braking. This brake has 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 this brake assembly 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.

Works just like they should and appear to be very good quality. The price is excellent and the best price around for a quality part. I purchased two left hand and two right hand brake assemblies to replace old busted brakes on my dual tandem dump trailer. I called to order and spoke with Christina J who was extremely professional and got my order out the same day I ordered even though I was close to the cut off time for shipping. The items arrived the very next day but unfortunately the brake shoes had been damaged in shipping and were not usable due to less than ideal packaging. I called etrailer and spoke with Benjamin A, he was very helpful and had me send a couple pictures of the damage while we were on the phone and within minutes had another replacement set sent out to me that same day and arrived the very next day. I am extremely happy with my customer service experience and this level of service is hard to find these days. The brakes are working good and I’m happy to have given my hard earned money to etrailer. This was my first purchase from them and I wish I would’ve worked with them sooner. I will be a repeat customer!


great part to replace that worn out rusty old brake assembly


Thalinks for my 10k electric brakes that I recieved 2 days after I ordered, and had installed them on my 40' gooseneck. They look just as good as the Dexter's I orders last time which cost me almost double.
I will be ordering from etrailer from now on.


The brake assemblies arrived on time and in great condition. They were packed well to prevent damage to them. Have already installed all 4 assemblies on our 9 ton equipment trailer. They were easy to install and works great.


watched an video trailer on the road every day breaks self adjust and are working great.


Outstanding quality at affordable price.
brake system was the best value I could find, and the technical help was spot on. Good job etrailer!


This was the best customer service experience that I have had in a long time! I highly recommend etrailer! The order came in an amazingly timely manner and were very high quality! Thank You Again! Brian.

  • 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!

  • Comparing Dexter and etrailer Brand Electric Trailer Brakes for 10K Axles
    We recently had a short training session in which the difference between our brakes such as # AKEBRK-10R and Dexter brakes were revealed. The biggest difference is the brake pad material. It is thicker on our house brand brakes. Also, on our brakes the pads are machine cut whereas on the Dexter brakes the sections are snapped off. The benefit to having them machine cut is a smoother edge. Snapping off the pad sections leads to chipped edges and fine cracks in the material. The performance...

  • Dimensions for the 7-Bolt Mounting Pattern on the Electric Trailer Brake # AKEBRK-10R
    Although we do not have a schematic for the 7 bolt mounting pattern, I do have the measurements for the patterns. The 7 bolt mounting patterns for both the Electric Trailer Brake with Dust Shield, Right # AKEBRK-10R and Left # AKEBRK-10L, varies between 2", 2-3/16", and 4" depending on what mounting hole locations you are looking at. I have provided a picture that shows the dimensions for you to reference.

  • Does Brake Assembly part # AKEBRK-10R Fit Dexter D100 Axles
    If your Dexter axles are 10k axles that require 12-1/4 inch by 3-3/8 inch assemblies the part # AKEBRK-10R would fit. Everything I am finding on the Dexter D100 axles is that they are 10k so these would be a fit. For the matching left side you'd want the part # AKEBRK-10L.

  • Replacement Trailer Brake Assemblies for Dexter 10K Axle
    The etrailer brand # AKEBRK-10R for the right side and # AKEBRK-10L for the left are the correct replacement 12-1/4 inch brake assemblies for a Dexter 10K axle with a 7-bolt brake mounting flange. I've linked to a product description video featuring the brake assemblies.

  • Replacement Electric Brakes for a 1991 Fleetwood Wilderness 5th Wheel Trailer
    I am fairly certain your 1991 Fleetwood Wilderness uses 10 x 2-1/4 inch brakes. But to be sure you can measure the inner diameter and depth of a drum. For a pair of brake in this size I recommend etrailer brakes # AKEBRK-35-SA which includes a left and right assembly. These are self-adjusting brakes that only require an initial adjustment at the time of installation. After that they will adjust themselves. I have linked a video featuring these brakes for you.

  • Replacement 12-1/4 x 4 Inch Brakes for 10,000 Pound Dexter Trailer Axles
    If your drums are 4 inches wide where the brake shoe pad makes contact with the inside of the drum then you will need 12-1/4 by 4 inch brakes # 23-438 for the left and # 23-439 for the right. If you are measuring the overall depth of the drum then you likely need the 12-1/4 by 3-3/8 assemblies such as # AKEBRK-10L which would fit on Dexter axles.

  • Will The Brake Assemblies For A 7 Bolt Flange Work With The 4 Bolt Flange?
    For a 9,000 lb axle with 4 bolts, you will want the Dexter Electric Brake Assembly, RH 12-1/4" x 3-3/8", # 23-435 and the matching left side assembly # 23-434. These are the only assemblies for the 4 bolt mounting plate and the 7 bolt plates are not compatible. Unfortunately, the Electric Trailer Brake with Dust Shield - Self-Adjusting - 12-1/4" - Left Hand - 10,000 lbs, # AKEBRK-10L, is an example of the 7 bolt flange that is not compatible with your axle.

  • Replacement Trailer Brakes For Dexter 023-451-00 Electric Drum Brakes
    The Dexter Electric Trailer Brake Assembly # 23-451 being the part number 023-451-00 that you referenced is a right side brake assembly. The Dexter Electric Trailer Brake Assembly # 23-450 is the matching left side brake assembly. This is available as a kit # 23-450-451 since I always recommend changing brakes as a set. We have the etrailer Electric Trailer Brake Kit # AKEBRK-10 which will can also be used. These are the same 12-1/4" x 3-3/8" brakes pads as the Dexter brand and they are...

  • Recommended Replacement Brake Shoe Kits for Dexter 12-1/4 x 3-3/8 Inch Electric Brakes
    The 12-1/4" x 3-3/8" Electric Brake Shoe/Lining RH # BP04-255 and Left Hand # BP04-245 are a fit for the Dexter cast backing plate. The Dexter brand is 12-1/4" x 3-3/8" Electric Brake Shoe Lining--Right Hand # BP04-250 and Left Hand # BP04-240. If you want the entire assemblies, we have # AKEBRK-10R and # AKEBRK-10L which are self-adjusting to maintain the best braking. This is my recommendation because you get an all new assembly ready to install and use. I've attached videos to assist.
