Free-backing, passenger-side drum brake won't engage when you reverse, even if your actuator is activated. Automotive-grade friction pads and e-coated backing plate are long-lasting. Fits 14-1/2", 15", 16", and 16-1/2" wheels.
Features:
- Hydraulic drum brake assembly is designed for use with a surge-type trailer brake actuator
- Free-backing design lets you back up without engaging the trailer brake, even if the actuator is activated
- Fall-away brake shoe only anchors on drum 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 gear allows for a more precise setting
- E-coated backing plate resists wear and corrosion
- Single plunger design
- Adjuster plugs (included) cover access holes to keep dirt and grime out of the assembly and off of the shoes
- Mounting bolts and hardware (BRKH12S) sold separately
- QAI and CSA certified
Specs:
- Application: most standard hub-and-drum assemblies, including Dexter, Lippert (LCI), and AL-KO
- Configuration: right hand (passenger's side)
- 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.
This free-backing hydraulic brake assembly 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.
This trailer brake assembly acts as part of your trailer's hydraulic braking system. A hydraulic trailer brake actuator is required for this brake to function.
Thoroughly Tested for Safety
This brake assembly meets the requirements for certification by the Canadian Standards Association (CSA). The CSA creates standards, which when complied with ensure a safe and quality product. This brake assembly underwent extensive testing to measure stopping distances when braking. This brake has 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 this brake assembly 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.

Brake assemblies fit perfectly in place of the OEM Dexter brakes. Quality looks fine, aluminum wheel cylinders are a notable improvement. We'll have to wait another 10 years to see if these hold up as well as the US-made Dexters.

Changing out the brakes on my boat trailer was actually much easier, and cheaper thanks to these guys, than I expected. etrailer.com had every single part I needed and the videos explanations made selection easy.
Will bookmark this site for sure.

Very helpful staff. I did all 4 breaks and bearings complete. Glad I checked things out, seals were gone and one wheel had bearings that failed and I was lucky I made it home. Also put on new brake lines and master cylinder, all good now. Tnks

I bought these new for less than the local brake materials shop quoted me to rebuild the old brakes. They have a nice coating that should resist rust for awhile. They seem to slow the trailer well. I would buy them again.

Review from a similar FreeBack 12 Inch in Accessories and Parts
Items were correct! Two boxes to ship the items. First box was damaged and required tape to keep the contents in tack. Second box was not damaged and contained two assembled backing plates. The right plate was missing parts (found in bottom of box) and the pin holding one of the shoes on was bent in two different directions. Had to straighten the pin in order to reassemble the plate and brakes.

As far as I can tell, everything will work. The box holding the left & right backplates looked like it had been dropped. I checked the box and found that one of the plates springs had broken loose. My husband fixed it. Maybe they should put into bigger box.

Review from a similar FreeBack 12 Inch in Accessories and Parts
Items are of good quality and easy to install. I had to make a small adjustment on the 5 mounting holes on the backing plate to 7/16" in order to use the original bolts since no hardware is supplied with the kit. The best was that all other parts were already assembled and factory set which made installation fast and easy. Also, by using the kit the cost of the job was less expensive then replacing all of the individual parts. This was a win win-win for me. Thank you etrailer.

After the old backing plate was removed from my 20 year old boat trailer, the installation of the new backing plate and break assemble took less then one hour . The drum with the bearings installed slid right on .

Review from a similar FreeBack 12 Inch in Accessories and Parts
Parts arrived on the date scheduled, the shipper for some reason couldn't find an address that they had delivered to before, this was not any fault of etrailer.com.
All parts fit exactly as they should have and now hopefully I will not have to fix someone else's neglect again, as shown in some of my pics. But if I do I will use etrailer.com.
Big thanks to Shawn for help above and beyond.

For our house etrailer.com brand we have the part # AKFBBRK-7R-D and # AKFBBRK-7L-D which is a 12x2 7k rated brake assembly that would work well for you. These are also dacromet coated which means they will resist corrosion.
view full answer... - How Do I Know If I Have Free-Backing Brakes?Your trailer must have free backing brakes if you have never used the surge brake actuating coupler reverse lockout. If you did not have free backing brakes, your brakes would most likely brake even if they didn't lock up when you back up because of the trailer weight pushing against the hitch ball. The only way to know for sure is to pull your hub/drum off the spindle and look at the hydraulic cylinder. Free-backing brakes like # AKFBBRK-7R-D will have only one pin coming out and it...

The spindle of these axles are usually come in odd sizes, making it them incompatible with standard trailer hubs and parts. If any of these part need replacing, then the standard trailer hubs and parts will not work and then you may have to change your axles. However, if you are going to reuse your wheel hubs and if you have a 5 bolt brake flanges on the axles, then we might be able to find the parts needed to convert over to hydraulic...

- Timbren Axle Less Setup for Trailer with 4 inch Lift and Surge Brake CompatibleBest option would be the Timbren Axle Less kit part # ASR35HDS05 which has a 3,500 lb capacity and has a 4 inch lift built into it. It has brake flanges on the spindle already too so all you need to do is attach the hydraulic style of assemblies you want as well as install the hub/drums. For a hub you'd need the part # 8-201-9UC3-EZ and for brake assemblies part # AKFBBRK-7R for the right hand side and part # AKFBBRK-7L for the left hand side.
view full answer... - Does Trailer Axle Determine Overall Capacity and Recommended 7,000 Pound Hub and DrumA trailer axle will typically be the best indicator of its overall capacity, but there are other components that may contribute to this as well. A trailer is always going to be limited by its weakest component. So, a trailer with two 7,000 pound axles will indeed have a capacity of 14,000 pounds, assuming that all other components on the trailer also match or exceed this rating. For example, if the trailer has two 7,000 pound axles but the hubs, wheels, or frame itself have a smaller rating,...
view full answer... - Choosing Replacement Trailer Brakes, Hubs and Actuator for 1978 Calkins Tandem Axle Boat TrailerYou'll want to check a few details on the trailer so you can select compatible replacement parts. First, you want to confirm the axles' rated capacity; this should be noted on a sticker or plate on the axles themselves. Based on the info you provided it may be that you have two 3500-lb axles. Your brakes and hubs must match the axle rating. Next you'll want to take note of the size of the current brakes. You need to confirm the diameter and depth. You also want to note their mounting...
