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.

Perfect replacement for my Eagle trailer with a 3500 pound axle. Wish the nuts came with the brake kit as they are not ordinary nuts to have laying around your shop or at least tell you nuts aren't included. 7/16- 20 nuts are needed. 892979

I have an 01 Bayliner 195 with an Escort trailer. The surge brake cylinder was shot and I thought I should go ahead and replace the brake assembly plates as well. I found it ALL right here when 6 local trailer companies couldn't help me locate the actuator. Better prices, cross referencing, fast shipping! Oh you can bet your sweet assassin I'm coming back when I need trailer parts!!! 882280

This is a excellent product. During shipping all 4 adjusting links came off in the box. An assembly diagram would have been helpful. One piece of paper. The nuts needed are not easy to find at a local store, (7/16th x 20) so buy the hard wear package too. 881271

  • Replacement Brakes, Hub and Drum Assembly with L44649 Inner and Outer Bearings on 2000lbs Axle
    I have a solution for you, but the # AKUBRK-35-D are 10" brakes and will be too large for the hub/drum assemblies that fit on your axle. Instead you'll want to use the Dexter # 23-398-399 which are a 7" brake assembly that can be used with wheels between 10" and 13" diameter. It sounds like you also need new hubs, so you can use the etrailer Axle Tech # AKHD-545-2-2K which are a 2000-lb capacity and have # L44649 inner and outer bearings to match your specifications.

  • Hydraulic Brake Line for Hydraulic Drum Brake Assembly # AKUBRK-35-D
    The Hydraulic Trailer Brake Kit - Uni-Servo - Dacromet - 10" - Left/Right Hand Assemblies - 3.5K # AKUBRK-35-D will fit the traditional 3/16 inch brake lines like # 18SI-BLKIT or # 20TA-BLKIT which have the thread size of 3/8"-24. You shouldn't need an adapter fitting unless you have the larger 1/4 inch brake lines. In that case the Replacement Adapter Fitting for Titan Hydraulic Brake Kits - 1/4" to 3/16" # T4871700 would be used.

  • How Do Hydraulic Drum Brakes Lock Up if Trailer Becomes Uncoupled From Tow Vehicle
    The etrailer.com Hydraulic Trailer Brake Kit # AKUBRK-35-D referenced in your question do not, by themselves, lock up if the trailer were to come unhitched. This is the case with any hydraulic brake assembly. The mechanism that allows hydraulic brakes to lock up if the trailer were to ever come uncoupled with the tow vehicle is located on the surge actuator, such as with the Demco # 8605001. This breakaway cable should be located on the top of your actuator (see attached image). You...

  • Replacement Hydraulic Drum Brakes for Dico 15638
    According to my research, the Dico 15638 Braking Assemblies that you have now are 10" x 2-1/4" therefore the correct replacement for you will be the Hydraulic Brake Kit part # AKUBRK-35-D for single servo or part # AKFBBRK-35-D for free backing. The single servo means that you will need to have some sort of manual or electric lockout on the coupler in order to reverse the trailer whereas the free backing do not require any sort of additional lockout. The price can be found by clicking through...

  • Compatibility between UFP HD1377 Drum/Hub and AKUBRK-35-D Trailer Brake Assembly
    The UFP HD377 is a 10 inch hub drum for a typical 3.5K axle. The # AKUBRK-35-D brake assembly you'd looked at is compatible with a 10 x 2-1/4 inch hub drum, as long a the inside width and depth dimensions of your existing hub match that, the assembly would work perfectly for you. I'd make sure that the inside surface of the existing hub/drum where the brake pads would contact are in good condition. If not, the proper replacement hub/drum is part # AKHD-545-35-K

  • Replacement Hydraulic Surge Brakes for a 1994 Eagle Trailer
    I can help you determine the correct size for replacement brakes but we don't have a database of parts for specific trailers. With bearings # L68149 and # L44649 this narrows it down a lot. If do indeed have a 3,500 pound then you'll need 10 inch brakes like the Dacromet Assemblies # AKUBRK-35-D. These are great for boat trailers because of their resistance to corrosion. The kit includes both left and right hand side brakes that are labeled to make the install easier. Also the bolts...

  • Do Brake Shoes Need to be Replaced if Grease Spilled on Them
    I empathize with you because accidents do happen but if grease got on the brake shoes of your Hydraulic Trailer Brake Kit # AKUBRK-35-D to be safe you need to replace the shoes in order to ensure proper braking. For that you will need two of the Hydraulic Brake Shoe/Lining # BP04-120; this shoe will fit single servo 10" diameter x 2-1/4" wide shoes like your kit has.

  • Fit of Kodiak 20TA-BLKIT Brake Line Kit with Hydraulic Drum Brake Assemblies
    The # 20TA-BLKIT brake line kit you referenced is indeed compatible with the # AKUBRK-35-D Hydraulic Brake assemblies you'd looked at, the line kit is compatible with bolt disc and drum brake systems. The brake assemblies will be compatible with your existing axles, assuming the brake mounting flanges have the 2-7/8 inch center to center bolt hole spacing. I've linked to videos featuring the line kit and the brake assemblies you'd looked at.

  • Replacement Hydraulic Drum Brakes for Trailer with 10-Inch Hub/Drums
    Thank you for the photo of your trailer hub/drum assembly which shows its diameter to be 10-inches. More than likely the drum depth dimension is 2-1/4-inches since 10 x 2-1/4-inch hubs are quite popular. Please refer to the photo I linked for you. Our range of hydraulic drum brake assemblies in this size is linked for you. These work for axle weight ratings of either 3500-lbs or 3750-lbs and they are compatible with wheel diameters from 13- to 15-inches. An example is single-servo brake...

  • Which Direction Should Star Wheel of Brake Assembly Move to Tighten Brakes
    The adjustment star on brake assemblies like the # AKUBRK-35-D needs to turn counter-clockwise to expand the shoes so you'd need to click the star "up" to tighten the brakes or "down" to loosen them as you'd view them from the back of the assemblies. You will adjust the brakes using that wheel until there is a slight but constant drag of the shoe pads on the drum. I have included a link to a video and at about the 4:39 mark our installed begins adjusting the brakes.

  • Troubleshooting Weak Trailer Brakes When Using Foot Pedal But Great Breaking with Manual Override
    It sounds like you have a proportional brake controller, like the Prodigy P3 # 90195, that activates the brakes on your trailer at the same time and with the same intensity as the brake pedal in your tow vehicle. What I think is going on is that you aren't adjusting the power output of the brake controller before heading down the road. The manual override will always provide the 12V of power but if you have the power output setting low on your brake controller (like a 5 or 6) then it...

  • How to Prep Brake Drums for Use with New Braking Assemblies
    The best way to prep your new drums would be to take them to a local shop and have them resurfaced. Although there may not be any visible pitting they could still be warped which could create more issues further down the road. You also need to make sure there is enough life left in the material which they will tell you before the resurfacing process. If you choose not to have them resurfaced then I recommend taking a bit of fine grit sandpaper and removing any surface rust off the top layer...

    The Hydraulic Brake Kit - Uni-Servo - Free Backing - Dacromet - 10" - Left/Right Hand - 3,500 lbs # AKFBBRK-35-D and the Hydraulic Trailer Brake Kit - Uni-Servo - Dacromet - 10" - Left/Right Hand Assemblies - 3.5K # AKUBRK-35-D are similar. The difference is the # AKUBRK-35-D is not a free-backing assembly meaning you will still have about 20% braking when in reverse without a reverse lockout solenoid or manual lockout.

    There is a difference between the two 3,500 lb 10-inch hydraulic brake assemblies you referenced, which is that one has a dacromet coating for better resistance to corrosion. Dacromet is an adhesive coating that gives added protection against corrosion so they are optimal for a boat trailer. - Dacromet Coating: Hydraulic Trailer Brake Kit - Uni-Servo - Dacromet # AKUBRK-35-D - Non-Dacromet: Hydraulic Trailer Brake Kit - Uni-Servo # AKUBRK-35 These are otherwise the same hydraulic...

    Essentially yes, all of them will work for your trailer assuming you have 3,500 pound axles and a 4 bolt mounting flange. However, there are some differences between the brake assemblies you mentioned. The # AKFBBRK-35 are free-backing brakes, meaning they will not engage when reversing with your trailer. If your trailer has a reverse lockout on it then this feature is not necessary. They're coated with an e-coat used for corrosion resistance. The Demco brakes # 40716-15 are galvanized...

    The Atwood 82541 you referenced was discontinued a while back. The replacement I recommend is the Brake Actuator with Manual Lockout - Bolt On - Drum - 2" Ball - 7,500 lbs # T63FR. Then for your EZLoader drum brakes I recommend the Hydraulic Trailer Brake Kit - Uni-Servo - Dacromet # AKUBRK-35-D if you have 10 inch drums or the Hydraulic Brake Kit - Uni-Servo - Free Backing # AKFBBRK-7 for 12 inch drums.

This actuator is zinc plated for corrosion resistance, will work with 1-7/8"/ 2" hitch balls, and can utilize an electric lockout like # T4748800 for easy reversing. It will fit a 3" wide tongue and comes with a one year warranty. I have attached a review video for you as well. Unfortunately, we would not have the correct brake cylinder...

We do not carry any replacement axles of that length but there is a great option for you with the Timbren Axle-Less Trailer Suspension System because it negates the use of axles altogether.
