Free-backing, driver's-side and passenger's-side drum brakes won't engage when you reverse, even if your actuator is activated. Automotive-grade friction pads and e-coated backing plates are long-lasting. Fit 14" to 15" wheels.


Features:

  • Hydraulic drum brake assemblies are designed for use with a surge-type trailer brake actuator
  • 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
  • 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, right-hand (passenger's-side) brake assembly, and mounting bolts included
    • Nuts and lock washers (BRKH10B) sold separately
  • QAI and CSA certified


Specs:

  • Application: most standard hub-and-drum assemblies, including Dexter, Lippert (LCI), and AL-KO
  • Dimensions: 10" diameter x 2-1/4" wide
  • Mounting flange bolt pattern: 4 bolt
  • Wheel size: 14" and 15"
  • Axle rating: 3,500 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.

My trailer is over 25 years old and my concern was if I was going to be able to get the right parts. Everthing was still the same as back then. Much easier to replace the whole Assembly as opposed to randomly replacing a part here and there. I now have a new trailer...well almost

Its been a year now since I have installed the hydraulic trailer brake kit assembly and drums to my boat trailer and they have been working as great as the day I installed them. No issues

Products are great customer service well……. I ordered the product on the 10th was suppose to be here the 17th called customer service the 17th guy tells me he apologizes the warehouse guys are slacking. They were unable to locate one of the items I ordered that’s why it hasn’t shipped. Not once did anyone reach out to me to offer to substitute. I am not some weekend trailer fixer upper. That might order 2-3 things a yr. I own a trailer rental company with 12 trailers in my fleet. I asked for over night shipping to get the items Friday so I could still meet my deadline by Monday as this particular trailer was scheduled to be rented starting Monday morning the 21st for 2 weeks. Your customer service agent said sorry we can’t offer overnight shipping on this order as we would be losing money…(had someone reached out to me between the 10th and 15th I would of had my order my the 18th) ….. well because of incompetent etrailer employees. My order was shipped ground despite requesting overnight shipping I lost a $3,000 dollar rental….. Because of that I am willing to pay double for a trailer part before I order from e trailer again.

The FREE BACKING trailer brake is the way to go. No more having to lock the system out before you back up. No more forgetting to lock the system out before backing up. Had this for a year now and it works like a champ. I love E Trailer, they have everything for my 5 trailers.

I have ordered complete brake assemblies like these in the past for my 5th wheel. They are great and easy to install. No need to fight those springs and keepers that hole the brake shoes to the backing plate, (Pain) just remove the wheel and four bolts, install plate and wheel and adjust the brakes. Done in less than 30 min. a wheel. You save time and money! Great way to do your brakes and I like E-trailer's fast delivery.

Still working great, no problems!

I did a total rebuild of my boat trailer. I ordered nearly all of the parts from etrailer. New carpet for the bunks new brakes and backing plates as well as a new brake actuator. New wheel bearings and seals. This trailer is old a 1974 but all of the parts fit I was satisfied with all of the products I received and the timely manner in which they were delivered to my door I am very happy with the fine service I received a t trailer and the help and selecting the right parts thank you very much etrailer.

Got everything installed and after testing, brakes are working well. I have no major complaints. Price is good. I could have spent a few extra dollars for the galvanized backing plates but this is for a boat trailer that only gets towed 25 miles or so each way to a freshwater lake once or twice a week during the summer, so I went the cheap route. A couple of notes: spend the 5 bucks on the accompanying hardware kit (nuts and washers). I didn't, figuring that I would just use the nuts and washers off of the old plates. Problem is that the bolts on the old plates were course thread and the bolts on these are fine thread. I had to go to about 4 stores to find fine threaded bolts in the right size. I would have saved myself a couple of hours on the install if I would have ordered the hardware from etrailer. Second, on my trailer, two of the bolts were stalled with the bolt head on the outside of the axle with the nut on the inside of the plate. With these new plates, the bolts are not removable, which meant that I had to install two of the nuts with an open end wrench rather than an impact socket because there was not enough clearance between the nut when threaded onto the bolt and the axle. Not the end of the world and even if I knew that in advance I would have still purchased this same product. But it did end up taking an extra few minutes for each axle to install the plates, so it is something that I thought that I would note here. Just a couple of quibbles that were specific to my trailer. But if I were to do it over again, I would still purchase.

These brakes look to be of good quality’. I am Replacing possibly the original set of four on an 18 year old boat trailer. Time with tell how these hold up in the saltwater.

Shipment arrives on time as promised and they sure look good. I have a dropped axle trailer and I installed with the traditional adjuster at 6 o'clock position but with my dropped axle, I was not able to adjust the brake from outside. So I called etrailer help desk and the lady took down all my information and told me someone will call me back within 24 hours and they did and gave me a sound advice. Clock the plate so that the left adjuster will be at 9 o'clock position and right adjuster will be at 3 o'clock position. I did it yesterday, adjusted the brakes from outside, bleed the brakes and it works like it should be. Thank you etrailer and your supporting team.

I have had nothing but problems with the backing plates. I have adjusted them about every time I have taken my boat out. One time my boat trailer locked up both tires going down the road about 35 mph. good thing it wasn't any faster or I would have been in the ditch. I'm going to change back to the Manuel lockout brakes once I can get all new drums and brakes.



- AKFBBRK-35

Very fast shipping on the brake assemblies. Make sure that you see if the assembly has studs in the backer plates. My axle did not have room to use studs in all 4 holes. I had to remove 1 stud and put in a bolt on each side. Nuts for studs were “not included”. This was my only aggravation with these plates.

Delivered in a timely manner. one shoe had slight damage but not bad enough to complain about. Have heavy boat that I bought used 4 years ago and trailer brakes had never worked. These bolted on easily, made slight adjustments and trailer brakes now work perfectly. Should have done this a long time ago. Very happy, will order from etrailer again if needing brake parts.

Basically I just bolted these on and they were good to go. I bled them. the price is good and every thing is new and clean. Costumer service was real good about answering questions about product. nice to talk to a person when ordering.

Excellent product for the money! Parts and pieces were exactly as described and the quality of everything was exceptional through the installation process. Let's hope that continues through the use and life of the product. Shipping times and customer service were also top notch! Thanks etrailer!

The order arrived quickly and packaged well. Only problem was that the lower staked in studs couldn't be used. Not enough clearance to get the nuts on after assembly to axle plate. I just knocked the lower studs out and replaced them with the studs & nuts that were on the original assembly. New assemblies look well painted and the brake pads look good. These units were installed on a 1988 boat trailer; replacing the original brakes. I hope I get as much or more life from these brakes as I've gotten from the originals!
