etrailer by AxleTek Trailer Brakes - AKUBRK-7

Driver's-side and passenger's-side hydraulic drum brakes feature a single-plunger design. Automotive-grade friction pads and e-coated backing plates are long-lasting. Fit 14-1/2", 15", 16", and 16-1/2" wheels.


Features:

  • Hydraulic drum brake assemblies are designed for use with a surge-type trailer brake actuator
  • 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
  • Periodic manual adjustment required
    • Fine-tooth brake adjustment gears allow for a more precise setting
  • E-coated backing plates resist wear and corrosion
  • Single plunger design
  • 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 (BRKH12) sold separately
  • QAI and CSA certified


Specs:

  • Application: most standard hub-and-drum assemblies, including Dexter, Lippert (LCI), and AL-KO
  • Dimensions: 12" diameter x 2" wide
  • Mounting flange bolt pattern: 5 bolt
  • Wheel size: 14-1/2", 15", 16", and 16-1/2"
  • Axle rating: 5,200 lbs, 6,000 lbs, and 7,000 lbs
  • Limited 1-year warranty


These trailer brake assemblies act as part of your trailer's hydraulic braking system. A hydraulic trailer brake actuator is required for these brakes to function.


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.

Parts arrived on the date scheduled, the shipper for some reason couldn't find an address that they had delivered to before, this was not any fault of etrailer.com. All parts fit exactly as they should have and now hopefully I will not have to fix someone else's neglect again, as shown in some of my pics. But if I do I will use etrailer.com. Big thanks to Shawn for help above and beyond. 436057

Got the 12" backing plates, have yet to install them. My past experience with Etrailer has been excellent! I am rebuilding a large boat trailer and they have had everything I needed to complete the job with great videos on how to install each component. They are the gold standard for an online business! 637918

Review from a similar etrailer FreeBack 12 Inch in Trailer Brakes


The product was very good with minor shipping damage. I believe it would be better to ship in one box per axle instead of four backing plates in one box, that is where the damage came from. Your people were very friendly,& easy to work with. The product was exceptional quality. 588009

Review from a similar etrailer FreeBack 12 Inch in Trailer Brakes


Everything was there. All assembled. The only thing I did before I mounted the backing plates was to remove the adjuster wheel and take it apart and put some marine grease on the threads and under the cap. Other than that, I just bolted it on the axle, hooked up the brake line, and I was good to go. That easy. 251403

I Purchased hydraulic drum Brakes - Uni-servo backing plates form Lisa D at etrailer. I could not be more pleased. The items arrived when they were supposed to and were exactly what they were supposed to be. Lisa was very professional and knowledgeable, and followed up through email. I needed the items fast, and even after priority shipping, the cost was less than i could have found elsewhere. I will use etrailer again should the need arise. 366544

I am very pleased with the brake system. It is installed and functioning very well on a heavy duty equipment trailer which is often called upon to haul in excess of 10,000

Review from a similar etrailer FreeBack 12 Inch in Trailer Brakes


Good quality parts and materials and/or coatings that will resist the salt water corrosion. Easy swap in for the old parts. I was replacing a set where one brake pad was cracked (the new ones are bonded instead of riveted) and one where the hydraulic cylinder had blown out and drenched everything in brake fluid. Well worth the cost and well worth the additional cost for corrosion resistance if you launch in salt water. 588833

I was initially concerned about finding the right parts as the trailer was fairly old. etrailer had just what I needed. The website is so elegant. I was able to find the right parts quickly and with comparative options to make a final selection. The how-to videos are great. This made installation a little more comfortable. Especially when you do not perform this type of work every day. The parts were of high quality and are working as expected. I highly recommend etrailer for any of your trailer needs. 544906

I received some great advice and help from Leeza in selecting the correct product for my needs. Without serial numbers or identifiable model numbers on my existing trailer parts, she was able to determine the correct parts for my particular trailer needs (on a 25 year old trailer.whose manufacturer is no longer in business). I received the parts in the time span indicated upon ordering, and they fit perfectly. A good experience all around. 410338

Brake assemblies fit perfectly in place of the OEM Dexter brakes. Quality looks fine, aluminum wheel cylinders are a notable improvement. We'll have to wait another 10 years to see if these hold up as well as the US-made Dexters. 311632

Ask the Experts about this etrailer Trailer Brakes
Do you have a question about this Trailer Brake?


  • Replacement 12 Inch Brake Assemblies Compatible with Old Warner Trailer Hub/Drums
  • You can absolutely use the Dexter 12 inch brake assemblies. If you have electric brakes then the Dexter Nev-R-Adjust Electric Trailer Brake Kit - 12" - Left and Right Hand Assemblies # 23-458-459 with your current hubs. You may also want the new mounting hardware # BRKH12. For a more economic option that will work just as well, you may want to consider the Electric Trailer Brake Kit - Self-Adjusting - 12" - Left and Right Hand Assemblies # AKEBRK-7-SA. If you have hydraulic brakes,...

  • Comparing the Dexter Duo-Servo Brake Kit with the etrailer Uni-Servo Brake Kit
  • The Dexter Hydraulic Drum Brake Kit # 23-336-337 that you mentioned are Duo-Servo brakes meaning they deliver the same amount of braking whether you are driving either forward or in reverse. The Hydraulic Trailer Brake Kit # AKUBRK-7 that you referenced are Uni-Servo brakes which means that they will still apply braking when going in reverse, just not as much (about 20% total power) as the Duo-Servo brakes. Unless you plan on doing a lot of backing up with your trailer and you need...

  • Replacement Brake Assemblies for a 7K Trailer with 12 x 3 inch Brake Assemblies
  • If you are just wanting to get new brake assemblies you could use part # AKEBRK-7-SA for 12 x 2 assemblies for electric brakes or part # AKUBRK-7 for hydraulic brakes. These measure 12 x 2 inches so they will fit in the hubs you have now, plus they are rated for up to 7,000 lbs axles like that you have. They also fit a brake mounting flange that has a 5 bolt pattern. Although this will work, I recommend going ahead and replacing your drums as well so that you have an entirely new system...

  • Parts to Convert Electric Brakes to Electric Over Hydraulic Brakes
  • Converting from electric brakes to electric over hydraulic brakes will give you the most effective braking setup available. You are going to need a number of different parts, and the HydraStar Electric Over Hydraulic Actuator Kit # HBA-10-252-82 will give you an electric-hydraulic brake actuator, a brake line kit, and breakaway kit. Because you have a triple axle trailer, you are going to need an additional hydraulic line kit # 9579-01. If you are interested in a new brake controller, the...

  • Brake Assembly Recommendation for Dexter Axles Rated for 5,000 lbs
  • Dexter SLR does not indicate the weight capacity of the axle, but if you have 5.2k rated Dexter axles the assembly part # AKUBRK-7L would be the correct left hand brake assembly. Or if you need both sides you'd want the part # AKUBRK-7 which includes a left hand and a right hand side. These fit the standard Dexter style brake mounting flanges found on 5.2 to 7k rated axles that have a 5 bolt mounting pattern.
