Driver's-side and passenger's-side hydraulic drum brakes feature a single-plunger design. Automotive-grade friction pads and e-coated backing plates are long-lasting. Fit 14", 14", and 15" wheels.


  • Hydraulic drum brake assemblies are designed for use with a surge-type trailer brake actuator
  • 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
  • E-coated backing plates resist wear and corrosion
  • 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

  • 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

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.

The parts were the correct brake kit that I needed and was nice to just have to put them on and not rebuild the backing brake plate. I think it is the only way to go when fixing your trailer brakes and I would recommended them to any one. It would have been way more expensive to fix it any other way.


This went into a 30 year old boat trailer. Lost a grease seal and coated the brakes. I wanted to replace everything. I wish I would of bought the hardware with brakes. Would of saved me a 60 mile round trip. Everything went together easy.

We do have the hardware available. It is part # BRKH10B.


The advice I got was spot on, and my parts arrived quickly and in excellent condition. Surge brakes and bearings were easy to install. I will continue to buy from etrailer. Thanks!!


As far as I can tell, they look to be correct. The order process was seamless and shipping was extremely fast. I will be delivering these to my customer as soon as some other items arrive, that were ordered through our normal network. You guys have a great setup and I certainly appreciate your service. I have saved your site to my bookmarks for future use. Thank you.



It worked out wonderfully for my customer.


Wow, Fast shipping. We're scheduled for delivery on July 11, I received them on Thursday afternoon July 7.
Excellent quality of components and priced fairly. Easy and accurate replacement of my old shoes.....I'm SO GLAD I went this route with etrailer!


This kit was easy to install and works great, fit perfectly. The times I have ordered from etrailer have always been a good experience!


Excellent company Fast shipping We'll do business again with this company

Received the hubs, drums bearings and bearing buddies and installed. The parts were exactly what I needed. A big thanks to Adam for all his help. Will definitely use etrailer again. Many thanks.


Fit well half the price of Mastertow !!!



Outstanding no issues they work as intended


Took longer than expected delivery date. It was 2-3 day shipping and it took 11 days.


because everything i ordered work out great and fast deliverly


This product made a huge difference on my boat trailer. The pressed studs are good and "bad" on my opinion. The set I replaced had a standard nut and bolt to attached the assembly. The studs are great, but forced me to use a wrench instead of impact to tighten the nuts on because there isnt enough clearance on my application for a socket. Installed fairly easy and there is a noticable difference in stopping ability. To be fair, the set a relaxed had no braking material and was simply metal to metal. I would def purchase again if needed. Great customer service as well. I got an email to let me know the product shipped, and something I havent experienced before, I also received an email from someone to let me know the parts were delivered!

A year later and everything is still working together very well. Thanks again for a great product!


exactly as advertised, good pricing


After about a year my trailer brakes ar working like they are still new!!!


I am super happy with my replacement of the electric brakes on my camping trailer with this Electric Over Hydraulic Actuator and Hydraulic Brakes. It works SO much better than electric brakes ever did. I feel much safer towing the trailer now.


Very grateful these were available, as I couldn’t locate locally. The only problem was the backing plate hardware didn’t match my Eagle boat trailer, ( my original backing plates had captivated nuts ) but very glad to have trailer brakes again

Thank you, Ray Wolfbrandt

Only comes with studs no nut for them. Speacal fine thread nut. Also shipping was very very unacceptable. Not happy

These brakes do come with the mounting bolts however do not come with washers and nuts. You can reuse the ones that you have if they are in good condition or we do carry replacements part # BRKH10B. Customer service will be in touch about the shipping experience.


These are the way to go easier and cheaper to install then the individual components . Pictire of old and new


These brake kits are a great solution instead of trying to piece together an old, rusty set up. I did R & R the new brake shoes just so I can lubricate the backing plate where the shoes ride and I did have to drill a 3/8" hole in each backing plate for the water flush fitting. That's just me. Other than that these were a breeze to install and could very well be installed as-is right out of the box.


Just what I needed to get our tow dolly back on the road.


The brakes I ordered and put on my 98 Nitro trailer a year ago work perfect, have no problem going off the mountain at all, would recommend them to anyone for trailer brakes.


OUTSTANDING price to value ratio. Perfect match for my 2005 Dorsey Dual Axel trailer for my boat. Great parts for the drum and brake kit and could not be happier with shipping time and speed.


It is just as described and went on perfectly!! I always like getting things that fit right the first time and look to be quality made.
The two that were on my trailer were in very bad condition (JUNK), and these solved my problem very easily. Also, they are at a reasonable price. +++++ all the way!!
The staff that helped me are fantastic in knowledge of there product and SERVICE! One of the best parts is the Fast shipping! A PLUS

Thanks all the way to everyone!


Was not sure if these brakes would fit my trailer so I called etrailer and told them what trailer I had and they confirmed fitment. Product arrived in a timely manner and fitment was excellent! Love that they are assembled and ready to bolt on. Great product and even great company. Thanks again!
