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: 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: David 01/13/2024
Nice. Perfect replacemen. For the price ace sends to just replace the whole loaded assembly vs pieces parts.
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.

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

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.

just installed brakes,install ok.just hoping to get more milage and time out of these brake .because in the past i have not,i have had cylinders lock up on me on both sides, mechanical issues sitting on the side of the road stinks.but i have also learned that these brakes are not install and go .they need to be adjusted thru out the year for better wear

The loaded marine grade backing plates made my job super easy. The fit was perfect and went smooth. I would like to see new nuts supplied with the studded backing plate. My order was processed fast and I received it quickly. Packaging was great.

Backing plates arrived on schedule. Installed just fine.
by: Chris04/18/2022
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.

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!
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.

Great buisness to deal with very prompt and helpful
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

etrailer has great products with fast and reliable service. I buy all my trailer supplies from them. I bought 2 hubs and drums for my boat trailer. I was going to give 4 stars because they did not include the 4 nut and bolts that hold the hub to axle with the product. (the old ones were so rusted they broke off), at the least they could offer for you to purchase them with hub. but I gave 3 stars because I went back to the reviews and others complained about the same thing. problem should have been fixed back then!!

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.

- Width of Hydraulic Brake Kit AKFBBRK-35-DThe width is 2-1/4" for the Hydraulic Brake Kit - Uni-Servo - Free Backing - Dacromet - 10" - Left/Right Hand - 3,500 lbs # AKFBBRK-35-D, so you will need hub and drums that are at least that wide for these to fit; though that width (or more) is standard for 3,500 lb, 10" hub and drum assemblies.

These are the best option as they repel water better than other trailer brakes and will offer superior braking. This will require the Zinc-Plated Brake Actuator # T47457107K and Brake Line Kit # HS496-251. The brake actuator uses a electric lockout so you will need a 5-way for your tow vehicle. If you have a 7-way then you will need an Adapter # A75TB or a Kit # C57187 can be used to change a 4-way to a 5-way. You could also go...

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.
