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.

  • Troubleshooting Brake Adjustment Wheel that Wont Adjust with Brake Spoon
    It looks like your adjustment star wheel is fully retracted to the point it might be too tight to adjust with a brake spoon like # W80630. With the hub off see if you can get the star wheel to break free so that it can start to adjust out. Maybe try grabbing the star wheel with a set of channel locks to really get decent leverage on it. You should be able to see the inner threads like in the picture I attached.

  • Replacement Brakes System to Upgrade 2006 Sea Doo Boat Trailer
    I'm happy to help with all the parts for your 2006 Sea Doo trailer. I did a little research and it appears it is a single axle trailer, for which I recommend the following parts: -Kodiak Disc Brake Kit - 10" Hub/Rotor - 5 on 4-1/2 - Dacromet - 3,500 lbs # K2HR35D -Kodiak Hydraulic Brake Line Kit - Single Axle - 18' # 18SI-BLKIT -Demco Hydraulic Brake Actuator w/ Electric Lockout - Disc - Zinc - 2" Ball - 7,000 lbs # DM62VR This combination is what I would use for excellent trailer brakes...

  • Hydraulic Drum Brake Actuator and Brakes for Dexter 8-201 Hub and Drum on Boat Trailer
    I have added a link to a help article on everything you need to replace (or add) hydraulic drum brakes, but let's start with the actuator. What you need to know is the weight capacity you need, the hitch ball size you are coupling to, and the size of your channel to mount the coupler (though there are also couplers for A-frames, though it doesn't sound like that's what you have). For example, the Titan Zinc-Plated Brake Actuator - Drum Brakes # T4079200 has an 8,000 lb capacity, couples...

  • What's the Difference Between etrailer AKFBBRK-7-D and Dexter T4489600-500 Hydraulic Drum Brakes?
    The main difference is brand. The # T4489600-500 is Made by Dexter here in the USA, while the # AKFBBRK-7-D is made by etrailer overseas. Both will work with the same hubs, and the same axles. Dexter also uses the Galphorite coating on those brakes which has a slightly higher salt-spray rating compared to the dacromet our brakes use, but its not really a noticable difference, as if you're actually going in salt water you should be going with galvanized brakes.

  • 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...

  • Replacement Hydraulic Brakes for a 10K Boat Trailer
    Thank you for the info! I believe that you are correct and you have 2 axles with about a 5K weight rating. With that being the case it means for replacement surge brakes you need 12" brakes. If you use drum brakes then I recommend the Kit # AKFBBRK-7-D because they have a Dacromet finish that will them last longer in regards to water exposure. If you happen to have disc brakes then I recommend the Kodiak Disc Brake Kit # K2HR526DS because it uses a combination of Dacromet finish and stainless...

  • Brake Kit and Hub/Drum Assembly Needed for 1994 Four Winns Single Axle Boat Trailer
    Since the spec sheet said 4,740 lbs per axle and you have 6 on 5-1/2" lug patterns I think it's safe to assume that brakes and hub/drums rated for a 5,200 lb axle would fit, but I would still try to double check on your end just to be sure. There should be an axle tag in the middle of your axle that says the exact weight rating. For a 5,200 lb axle you'll use the following: Electric Brakes - # AKEBRK-7-D Hydraulic Brakes - # AKFBBRK-7-D Hub and Drum Assembly - # AKHD-655-6-EZ-K (comes...

  • Solution for Manually Locking Out Brakes on Actuator With Electric Lockout
    If you have an actuator like the Dexter # T4750620 you looked at, the only way to lockout the brakes is with the electric lockout. If you have a different model it is possible it has a spot for a key on the side like the # DX94FR which would work with an actuator like the # DX56FR. If you do not have this, there is still a solution for your problem. Although you can't manually lockout the actuator, you could add free-backing brakes to your trailer. These eliminate the need for the lockout...

  • Determining Boat Trailer Drum Brake Size With an Measurement of 14" Across The Backing Plate
    The diameter of a drum brake is measured inside the hub so your 14" outer diameter is most likely a 12" drum brake. Depending on the age of your axles on your trailer I may be able to look up what the manufacturer installed on the axle by the serial number. This is generally found on the tag in the center of the axle. If you are only looking for a replacement brake assembly this is generally determined by the weight capacity of the axle. The Hydraulic Brake Kit # AKFBBRK-7-D fits on 5,200-7,000lb...

  • Can Hydraulic Drum Brake Kit # AKFBBRK-7-D be Used with Electric Over Hydraulic Actuator
    Yes, the Hydraulic Brake Kit # AKFBBRK-7-D that you referenced will work with electric over hydraulic actuators. For drum brakes the best actuator is the Hydrastar part # HBA-12 as we have found that it reacts very quickly and is very reliable.

  • Are New Hubs/Drums Required To Use the Hydraulic Brake Kit AKFBBRK-7-D
    If you replace the braking assemblies with the same size you currently have then you won't need new hubs and drums as well. The Hydraulic Brake Kit part # AKFBBRK-7-D measures 12" diameter x 2" wide which is standard for a 5,200 lb - 7,000 lb axles so as long as that is what you have then you won't need to replace the hubs and drums as well.

  • What is Difference Between Uni Servo and Duo Hydraulic Brake Assemblies for Trailer
    Uni servo and duo servo is basically the style of wheel cylinder. It basically puts pressure on either side of the cylinder. The styles are interchangeable so if you have one style over the other you can go with either style. As long as your drum size is 12 inch and your axles are 5.2k to 7k the part # AKFBBRK-7-D would fit and work well.

    Based on my research, your Karavan US-4100-78-SSB-ST trailer uses standard 12" x 2" drums, so for a set of hydraulic brakes, I recommend the Hydraulic Brake Kit - Uni-Servo - Free Backing - 12" - Left/Right Hand Assemblies part # AKFBBRK-7 (black powder coat finish) or part # AKFBBRK-7-D (dacromet finish). These are compatible with 5,200 lb, 6,000 lb and 7,000 lb axles. For the mounting bolts and hardware, you can use part # BRKH12.

  • 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 recommend...
