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

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.

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

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


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


The ordering process was easy. The price was reasonable. The product was exactly what I wanted. I have more parts I need to order for my trailer and I will use etrailer when I do.


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


Excellent quality


These brake assemblies came to Me looking great, They fit great, work Great, and best of all was the Great Price and the free shipping! 5 STAR's for this Product. Also I want to give a 5 STAR Rating for Your Customer Support, The Fast Shipping Notifications, and the After the Sale Follow up. Keep up the Great Work.

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.


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.


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

Great prices, fast shipping!




Fit well half the price of Mastertow !!!


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!

Great product, price and service


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.


Speed of delivery and tracking was excellent. The product looks good. I will purchase parts through your company again.


Fits perfect and good quality and price


Great customer service Got parts quick, fit perfect will do business with them again


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!


Well packaged, however, the nuts for mounting maybe should have been included. There were none in the box.


Received everything a day before it was due. The trailer is 38 years old and due to your excellent web site I was able to correctly identify the correct part numbers for my trailer. This is the second time I've used etrailer for parts and both times my experience was excellent.


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.


The product fit very well


Only down side is when used on drop axel they are hard to adjust due to a 8 small notches in the manual adjuster.
