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 assemblies and right-hand (passenger's-side) brake assemblies included
    • Ideal for building multiple trailers
    • Mounting bolts and hardware (BRKH1225) sold separately
  • QAI and CSA certified


Specs:

  • Quantity: 25 left-hand and 25 right-hand assemblies
  • 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.

Very happy with all the items. Quick shipping and all appears to be of decent quality.



by:

Placed order on a Sunday. Parts were in stock but shipped on a Thursday. If you batch and queue shipments you should say that in your shipping information. Also, the packaging was completely unacceptable. Both parts stacked in a box with nothing to keep them from banging against each other. Upper brake assys had chipped brake lining. The other, missing bleeder cap.
