etrailer by AxleTek Trailer Brakes - AKFBBRK-7-D

Marine-grade, free-backing hydraulic drum brakes won't engage in reverse, even if your actuator is activated. Automotive-grade friction pads are long-lasting. Dacromet-coated backing plates resist rust. Fit 14-1/2" to 16-1/2" wheels.


Features:

  • Marine-grade hydraulic drum brake assemblies are great for boat trailers
    • Designed for use with surge-type trailer brake actuators
  • Free-backing design lets you back up without engaging the trailer brakes, even if the actuator is activated
    • Fall-away brake shoes only anchor on drums when brakes are engaged as trailer is moving forward
  • 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
  • Dacromet coating on backing plates offers superior corrosion resistance
    • Ideal for use on a boat or snowmobile trailer
    • Durable enough for saltwater applications
  • Stainless steel springs are durable and rustproof
  • Aluminum hydraulic cylinders resist rust
  • 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


Note: Because free-backing brakes are designed to eliminate nearly all friction between the brake shoes and the drum when you are driving in reverse, a trailer breakaway kit will not be effective should your trailer disconnect from your tow vehicle while you are backing up.


Free-Backing Brake Assembly

Free-backing brakes let your trailer move in reverse without the brakes being activated by your surge actuator. These brakes are needed if your actuator does not have a reverse lockout, which is a mechanism that ensures that the actuator does not activate when your rig moves in reverse.


Each of these free-backing hydraulic brake assemblies has a fall-away shoe, which provides full braking when your trailer is moving forward, but supplies only limited friction when the trailer is moving in reverse. During normal forward braking, the fall-away shoe expands to catch your brake drum. When driving in reverse, however, the fall-away shoe's extra spring will overcome the pressure from the brake cylinder. This keeps the leading edge from catching on the drum, so the shoe will not fully pivot into the drum. This exerts a smaller amount of friction, just enough to provide a minimal amount of braking when in reverse.


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.

Easiest brake job I ever did! Complete assembly bolted to the trailer in the original position. No fussing around. Connected brake line, bled brakes and was rolling again. With free shipping, I couldn't go wrong. 394802

Great on phone help….. OK was very impressed that the 2 ladies I talked with on 2 different calls really knew their STUFF. Very impressed and ordered on Sat. del. on Wed. with tracking sent to me. Will be back when I break these in with new salt water. 375750

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


Comments

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

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

The crew over etrailers work their butt off I ordered the wrong 12 inch backing plate with shoes it was already loaded on the truck they went out and pulled it from the truck and did not charge me and reordered and sent the right product it a ride fast 430470

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

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

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

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

  • Replacing Hydraulic Drum Brakes on 1991 EZ Loader Boat Trailer
  • To determine the correct hydraulic drum brakes to replace those on your 1991 EZ Loader two axle boat trailer, you will want to measure the drum behind the wheels. Based on the pictures you sent and the information you provided, the axles on the trailer are most likely either 3,500 or 5,200 pound axles. Using this, along with the the fact that the axle has a 5 bolt mounting flange, the compatible replacement is most likely going to be hydraulic brakes rated for 5,200 pound axles. I...

  • Replacement Backing Plates and Brake Lines for an EZ Loader Boat Trailer
  • Thanks for the photo! I called EZ Loader and they were able to give me the information I needed based on your VIN. In order to replace the backing plates you are going to want to use the Hydraulic Brake Kit part # AKFBBRK-7-D. In order to replace the drums you are going to want to call EZ Loader directly as we do not carry the correct ones for your trailer. However, if you just need the bearings you can use part # LM67048 for both the inner and outer. If you are also looking to replace...

  • Selecting Replacement Free-Backing Hydraulic Brakes for Tandem 6K Trailer
  • Trailer brakes are left- and right-hand specific but not front and back. So for a tandem 6K axle setup you'll use two left-hand and two right-hand 12 x 2-inch free-backing hydraulics brake assemblies. For a high value-for-the-dollar option I like the AxleTek brake pair # AKFBBRK-7-D. All choices are shown on the linked page. We label our brakes left and right, but you can always use the rule that the shorter of the two brake pads on the assembly should face forward.

The seals that are included with our hub and drum assemblies, like the part # AKHD-655-6-EZ-K you referenced, come with grease seals that are compatible with the most popular spindles, but that doesn't mean they fit all spindles. You simply need to purchase grease seals that have an OD (outer diameter) of 3.376" and an ID (inner diameter) that is closer to your 2.13 measurement.
