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 13" to 15" wheels.


  • 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, right-hand (passenger's-side) brake assembly, and mounting bolts included
    • Nuts and lock washers (BRKH10B) sold separately
  • QAI and CSA certified


  • 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: 13", 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.

I needed drum brakes quickly so I could get my boat in the water. They were helpful in getting the right parts quickly. 621675


Ordered the brakes and two days later they were here! Haven’t installed them yet. Did notice they don’t come with the nuts for mounting but that’s easy. 655844


Excellent product that replaced 25 year old brakes on a boat trailer at a fraction of the price that local dealers wanted for them. I found all of the parts I needed by searching the site and everything installed very easily. 562004


At first had a little problem with my credit card authorization. You all made sure that it went thru and notified me right away to let me know it would ship on time. Not only was the product shipped quickly, but was packaged well and fit perfectly. No problems what so ever. From someone that works in the service industry, you all are an example to others on how it should be done. From the website videos to the support to the front door, excellent job!!! Will order again!!! 526855


Matched and replaced the OEM brakes on our boat trailer with no issues. The directions which came with them the brakes were not clear on which way to turn the "Brake Adjustment Star" for adjusting the contact of the brakes. The directions did not indicate rotation of the Adjustment Star being different from the left to right side brakes. This created some confusion due to the left side adjusted with no issue but cause the right side to be difficult until correction direction of rotation was determined. These brake work great and we are very pleased with all the other products we have purchased from etrailer.com 542275


Fantastic way to repair brakes on trailer. Actually less cost than buying individual parts to complete the job. Both sides completed in under 2 hours. Will be sure to tell everyone i know that has trailers to used this site for all of their needs. This is the 2nd trailer we have done brakes on, Extremely happy i found this site. 545454


Very, very prompt shipping! Customer svc rep very knowledgeable about hydraulic trailer brakes. Packaging ensured product arrived without damage. TWO NOTES: The brake line threads were not "well cut" on the right side wheel cylinder. To solved needed to "re-tap" the threads-- additional time required-- To make kit 'complete'--add 8 lock nuts to the package--will add about $0.80 to the kit and solve customers frustration of trying to find lock nuts with 5/8" across the flats. 11/16" across the flats will not work as too close to the welded axle on the mounting flange 385816

Thanks for the follow up and reply. I did want to let you know that part BRKH10B is available and is linked as a related item. This item included 8 nuts and lockwashers.
-- Rachael H - 09/14/2017



These backing plates were a great fit, good quality for the price and easy to adjust. The packing job e-trailer did for shipping was great. 658639


all parts fit very well, will order again in the future 606499


Here is some pictures of the before and after pictures of my boat trailer brake restoration. I contacted your customer service and told them what I wanted to do and they sent me all the parts that I needed. Everything went very smooth and all parts fit perfect. Thank you so much for your help and expert advice. Thanks again 590297


This review is for the Hydraulic Brake Kit - Uni-Servo - Free Backing - Dacromet - 10" - Left/Right Hand - 3,500 lbs - AKFBBRK-35-D. This worked perfectly on my 2008 Bear pontoon trailer with Axis branded 3,500 lb tandem axles and hydraulic surge brakes on one axle. It all went together smoothly without issue and after repacking the bearings and bleeding the system, the brakes now work again. A special thanks to Jameson for your time and recommendation on this kit, it was spot on! 352521


Great brakes, work very well. Bolts would be helpful, 7/16 -20 bolts are a hard find, had to go to a specialty hardware store to find them. 505415

The brake assemblies use integrated studs to attach to the brake mounting flange, not bolts, as stated in the product description. Lock washers and 716 inch nuts are available as part # BRKH10B
Mounting Hardware for 10" Brake Assemblies
. Each set includes enough nuts and lock washers for attaching two brake assemblies.
-- Mike L - 05/09/2018



The brakes are great. Easy to install as one whole unit. I can not speak of the quality, I put these on a 22 ft boat trailer and used it for one season. it is not boating season for me right now but i will look at them in the spring when its time to get the boat ready. 757188


Brakes working great 756889


I bought a home made trailer and Tim helped me figure out what axles were under the trailer and what products I would need to bring the trailer up to operational standards. He advised me to get the rust resistant hardware and fixtures. The break components are bolt on and pre assembled. A big help for a man my age (71). The easier the better for me. Bearings were in the drums so all I have to do is grease and install. All components are well made and coated with rust resistant material. Tim made the ordering process simple and painless. Cost is competitive and shipping is free over $xx.xx dollars. Who could ask for more. Very Happy customer. Steven 751578


Was working on boat trailer & needed parts that would work. They worked good & got it delivered to my home in record time.! 751328


Originally I wasn't sure of the pieces need to make my trailer work properly. I contacted etrailer and with a little guidance I ordered the proper items and now my trailer is working perfectly. I will definitely order again if needed and would recommend to anyone needing assistance. 746471


Great replacement-first time brakes have worked correctly on my trailer in 15 years 729441


I restored an old concrete buggy that I purchased surplus from a rental company. It was in pretty bad shape. I got it sand blasted. I painted it with Rustoleum. I installed new brake parts, master cylinder, and wheel bearing kits. Pretty big project but it came out great! Now I have a great little dual-axle dump trailer designed to carry a cubic yard of ready mix. Works great for short loads of concrete and for drain rock and landscape materials too. I had to use JB Weld to get a good seal on the new plastic master cylinder cylinder-to-brake-hose connection, which was a pain because it leaked and required multiple attempts to fix. Plastic threads on the plastic master cylinder didn't seal with teflon tape. They are easy to over torque/strip! Maybe I did that initially, but JB Weld fixed the problem. etrailer brake assemblies were easy to install and of very good quality. Fast shipping. Thanks! 725321




Brakes work exceptionally well, I would buy them again for my next project boat trailer !!!! 699378


High quality with very fast shipping. I will be a definite return customer! 696930


Exactly what was needed. 692256


Thanks to help from etrailer in finding the right parts - these were a perfect fit. My boat trailer sees lots of saltwater and these are holding up really well. 691321


I had a wheel cylinder leaking and instead of replacing just one I figured the other one will go bad in time so why not replace everything with new backing plates, brake shoes, and wheel cylinders. To me it was a good investment and one less worry on my boat trailer ( trailer is a 1990) . Everything works great and well worth the money. 690972

  • Comparing Free Backing and Duo Servo Hydraulic Brake Assemblies
    Good questions. The difference between free backing brakes like the # AKFBBRK-35-D and regular hydraulic drum brakes like # DMSB18794M-93M (referred to as duo or duel servo) is that the wheel brake cylinder has pistons on both sides of the regular/duo servo brakes instead of just the one side on the single servo free backing assemblies. The amount of braking doesn't change much between them, they just function differently yet under the same amount of hydraulic pressure. The duo servo...

  • Difference Between Demco 10 inch Drum Hydraulic Brakes and etrailer.com Brand Brakes
    The big differences is basically pricing and brands. The part # AKFBBRK-35-D is a pair of Dacromet coated drum, hydraulic brakes that are free-backing. The part # 40716-15 is essentially the same thing buy made by Demco. The etrailer brand is going to cost less since it's our brand and there's not as much markup so it's the better deal. Now the part # 40716-15 is basically just the part # 40716 and # 40715. What doesn't make much sense though is the pricing difference. It would seem...

  • How To Determine If Boat Trailer has 10 Inch or 12 Inch Brake Assemblies
    When determining if you need 10 inch or 12 inch brake assemblies there are a couple of easy things to check to confirm the fit for your trailer. The first thing is you can measure the diameter of your hub. The second thing is you can look at the brake flange, if it has 4 bolts then it is 10 inch if it has 5 then it is 12 inch. Because you know you have a #84 spindle we can be confident that you have a 3,500 lb axle and you will need the 10 inch assemblies. I recommend the Hydraulic...

  • How to Determine Which Hydraulic Brakes to Use on a Trailer
    There are two different types of hydraulic brakes used on a trailer which are disc brakes and drum brakes. A drum brake has a small round drum in which the shoes inside the backing plate push up and out to slow the trailer whereas a disc brake assembly is composed of a circular round rotor and half moon shaped caliper which clamps down on the rotor to slow the trailer. I have attached a photo of both to give you a better understanding. The part number you provided "KH8444" was manufactured...

    The adjustment procedure you mentioned of tigthening the adjustement till you can't turn the wheel by hand and then backing off 10 clicks is the standard way to adjust brakes and would be the correct way to adjust the Hydraulic Brake Kit # AKFBBRK-35-D that you referenced. If you follow that procedure with these assemblies you'll be good. I also attached a video that shows how to adjust brakes as well. At about the 4:39 mark our installer begins adjusting the brakes.

    Do you by chance have a 3,500 ALKO axle 8500? Or an 8,500 lb axle? I believe you'd have the 3,500 lb axle but wanted to be sure. For 3,500 assemblies you'd want the part # AKFBBRK-35-D as replacing all of the individual parts you mentioned would end up costing more and be more labor intensive. For a brake line kit then we have the part # 9504 which would fit and work well.

  • Difference Between Single, Dual and Free Backing Servo Brake Assemblies
    The biggest difference between the servo styles that you'll notice is between free backing plates and the others. The free-backing plates will allow your trailer to back up without having the brakes lock up. With surge brakes typically when you go to reverse the trailer it pressurizes the brake system which locks the wheels up. Free backing setups are designed to allow the pressure to build but not activate the shoes of the assembly so the trailer can back up. Some surge brake trailers...
