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" to 15" 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, 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.

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!

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!
by: David 01/13/2024
Nice. Perfect replacemen. For the price ace sends to just replace the whole loaded assembly vs pieces parts.
by: Tim07/05/2023
The quality of the unit seems fine, however they manufacturer is so cheap that they do not include the 8 nuts to hold the brakes to the axle. They expect you to to use the old nuts, in a perfect world that would be fine. Assuming your old bolt bolts and nuts are the same thread! Spent another $12 on nuts which is it a big deal but the hardware store was closed so I had to wait till the next morning. Wont order again.
by: Donald06/05/2023
The brakes work great. The new assembly had studs for mounting to the trailer and the nuts and washers were not included, so I had to get my own. Your information for ordering should make that clear.

The brake assemblies that we carry do not have hardware included and we mention it on the product pages. In case you want a complete new set of hardware, we offer part # BRKH10B as a quick way to get it.

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.

The boxes containing the brake kit was badly damaged due to transit. One of the springs popped off and the brake shoes were no longer aligned properly. Packaging was extremely poor. Hopefully there is no damage that I couldn’t see.

My new brakes look and fit great. This made the replacement on my Heritage boat trailer very easy. The quality looks great and should last me a long time.
Thanks etrailer for your help!

I installed these on my 1995 dual axle DHM trailer which carries my '95 closed bow Ski Nautique. The finish is stout and set up very easy. Had a bit of a challenge installing one nut on each side due to close tolerances between the backing plate and axle support but once on, the remaining three when on easily. Recommend doing this over trying to replace just the shoes.

Had to replace the old 20+ year old Attwood brake system. Both the brake assemblies and the coupler are working great.
by: Tye01/10/2022
The product looked great and I got great service. I was unable to use the brakes, though because I needed 5 hole backing plate instead of the 4 hole backing plate. I never got around to seeking a return, my fault.

Good product, fit very well and easy to adjust when installed ( lubricated the adjuster anyway) After a year of in and out of the salt water once a week for the season they look very good, a little rust, but not bad. Will see next year how they stand up.

Update: brake pad came off and locked up trailer wheel yesterday. Told only 1 year warrantee on workmanship issue. 2 years and now I need new brakes because they failed.
by: MNDIY05/27/2017
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

- Compatability of Hydraulic Brake Kit AKFBBRK-35-D and Hub and Drum Assembly AKHD-545-35-EZ-KYes, the Hydraulic Brake Kit # AKFBBRK-35-D is compatible with the Trailer Hub and Drum Assembly # AKHD-545-35-EZ-K. Just note that the hub and drum assembly have a standard black powder coat finish while the brake kit has a dacromat finish that is geared more towards a boat trailer that will be exposed to water. If you're looking for something that is designed to stand up better to water then you'll want to go with the Hub and Drum Assembly # AKHD-545-35-G-EZ-K with the galvanized finish...
view full answer... - How To Add More Stopping Power to EZ Loader Trailer with Drum Brakes on One AxleYes, your best and most cost effective option for increasing the braking on your trailer would simply be to add brakes to the other axle. You really can't go with a larger size without replacing the axle and switching to disc won't increase stopping dramatically considering how much it will cost. Therefore, I recommend a second set of drum brakes and it sounds like you would need the Hydraulic Trailer Brake Kit part # AKFBBRK-35-D and Easy Grease Trailer Hub/Drum Assembly part # AKHD-545-35-G-EZ-K....

view full answer... - Is It Worth It To Convert Surge Brakes On 1999 Jayco Eagle To Electric, Or Get New Surge Brakes?It's definitely way less work to keep what you have, surge brakes, than it is to convert everything to electric. Personally I'd just stick with surge brakes, as the only benefit you really get to electric brakes is the adjustability of the brake controller, and I don't think you'll see a big enough benefit to justify the cost. You'll need to know what size brakes your hubs take by either getting a part number from the hub, or measuring the inside dimensions shown below. The most common...

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...

view full answer... - Will the Hydraulic Brake Kit for 3,500 Lb Axles Work with 13 WheelsIn regards to wheel size compatibility, this comes from the hub as the surface area on said hub is what dictates the wheel size. Therefore, if you're already using 13" wheels with your existing hubs then there won't be any issues with the Hydraulic Brake Kit part # AKFBBRK-35-D.

- How to Determine Which Hydraulic Brakes to Use on a TrailerThere 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...

- Recommended Free-Backing Hydraulic Brakes for Surge Brakes Without Reverse LockoutAll hydraulic brake drum systems are compatible with free-backing brake assemblies like # AKFBBRK-35-D for 3500 lb axles with 10 inch drums or # AKFBBRK-7 for axles 5.5K to 7K with 12 inch assemblies. The brake lines are run to the brake cylinder that only has a single piston to allow movement in reverse without engaging the brake shoes to stop the trailer.

I am guessing that you have 3,500 lb axles on your trailer but if you could verify that it would help me to make sure that I recommend the correct parts for you. Also, are you looking to add brakes to both axles or just keep them on one pair? You would get more braking power and less wear with brakes on all of the axles but if you only want them on one then that will also play into the parts.

Basically, there are two ways to stop surge brakes from actuating when backing up the trailer. The first and most popular way to do this is to use a surge brake actuator with a reverse lockout. For example, the Dexter DX7.5L A-60 Brake Actuator# DX56FR has an electric lockout. The solenoid is wired to the reverse light circuit on the tow vehicle. This way when the vehicle is put in reverse, the actuator will be locked...

- How Do You Back a Boat Trailer On The Boat Ramp When The Electric Lockout Is Unplugged? You typically have a couple options Steve. The most commonly used is just waiting until the boat is on the ramp and then unplugging the wiring. This way you can let gravity take the boat down the ramp rather than pushing it with your truck. Another option which will depend on your surge brake is a manual lockout like the Key # DX94FR. This prevents the actuator from sliding and the brakes from activating in reverse.

None of brands of brakes that we carry will come with the nuts or lock washers. We mention this on the product pages for the brakes. Some want to re-use what is on the trailer and some want to replace it. We do carry a replacement set as part # BRKH10B.
