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.


  • 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


  • 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.

The brakes are great. Easy to install as one whole unit. I can not speak of the quality, I put these on a 22 ft boat trailer and used it for one season. it is not boating season for me right now but i will look at them in the spring when its time to get the boat ready. 757188


Excellent product that replaced 25 year old brakes on a boat trailer at a fraction of the price that local dealers wanted for them. I found all of the parts I needed by searching the site and everything installed very easily. 562004


Just as promised. Brakes are working wo nderfully. 875581


They were very helpful with orders and I was happy with how fast it was delivered 882998


The parts are exactly as advertised and they arrived on time. I would recommend etrailer to anyone who needs trailer parts. 870211

The brakes fit perfectly and work great 855450


Easy to install and fits perfectly for my 1985 EZ loader boat trailer. After one year they seem to be working great. 853716


Coated for a boat trailer, didn't rust up and fall off like most of them the first year. Adjusters froze and needed cleaning, pads are good still. Coating is starting to wear off, I figure if they are still less than double for the cheapest ones they should last 2x longer so I would use them again, unless I can find something way better. But like most of them , change them out before a long trip each year and that's just the way boat brakes are. 844175


Product was received when it was promised. However, the nuts to attached the brake kit to the axle were missing. It would have been nice to include them in the kit. Instead i had to run the the local hardware store to purchase 8 nuts for $3.60. 829540


Bolted on to the flanges on my trailer so easy install. I had to order nuts and washers separately 828454


Perfect fit..... works great ....thank u 827912


Glad I could purchase the entire assembly rather than replacing everything piecemeal. This will make it much simpler, and better when done. I was also very impressed with the purchase and delivery process. Of everything I have purchased online, this was the most efficient process I have seen. Great job! 820788


It would be nice if they came with nuts and lock washers. Also, the brake adjustment opening in the backing plate is directly behind the drop axel making adjustment difficult. 819659


Great looking product and it fit perfectly. Super easy installation, but the 7/16-20 nuts for the mounting lugs were not included. 818565


Brakes working as they should. Were easy to install, just not the easiest to adjust - difficult access. Just pulled boat out of storage for the first time this season, and all is well with the brakes. 808374


Easy to install. For me, the through bolts, instead of studs on the backing plate, would make it easier to get at with an impact. Overall, very good product. 808137


Recommend to everybody 808087




Great service and great product. They communicated everything you needed about shipping and when it would arrive. My favorite aspect is the helpful videos. I will use this company for all my future needs. 801173


These brakes are a perfect fit as an OEM replacement!!! 800099


Great quality product. Everything bolted right together. 799894


Works perfectly. I love that I can back up without having to get out and lock the tongue. Easy to adjust and worked after storing over winter. 790422


Easy replacement, perfect fit. Tara from customer service was great in assisting and reassuring that this would fit without complications. Thank you. Would but again 786388
