    • 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
  • Dacromet coating on backing plate offers superior corrosion resistance
    • Ideal for use on a boat or snowmobile trailer

  • Mounting flange bolt pattern: 4 bolt
  • Wheel size: 13", 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.


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.

Video Transcript for etrailer Trailer Brakes AKFBBRK-35R-D Review

Today we're going to take a look at the 10" Uni-Servo Free Backing Hydraulic Trailer Brake Assembly for 3,500lb axles. This is a right hand passenger side assembly and as you noticed it has a nice Dacromet matte finish to it. This hydraulic drum brake assembly is a Uni-Servo free backing design, which is used on trailer with surge type brake actuators with no reverse lock out. The Uni-Servo design, you can see right here, it's a single plunger design, the free backing design, the free backing you can always tell by the shoe that it has sort of a D shape to it. This design will let you back up without engaging your trailer brake, even if the actuator's activated. Basically the shoe, it's a fall-away shoe, provides full braking when your trailer's moving forward. That supplies only limited friction when the trailer's in reverse.

The other nice thing is the Dacromet coating over the whole wheel or over the whole brake assembly. That is used in marine applications because that coating provides superior corrosion resistance for fresh water or salt water use. The size on this is 10" by 2-1/4" passenger side electric brake assembly. When they say 10" by 2-1/4" what that measurement is, 10" would be from here to here, so straight across the diameter and the 2-1/4" would be the width of the pad on the brake shoe. If we take a ruler and go edge to edge you can see 10" and if we go the width of the pad right at 2-1/4". 10" by 2-1/4" and I did mention this is the right hand passenger side. A good way to tell what side this assembly goes on, on a new brake assembly it will always have a tag that'll say right hand or left hand.

That's the best way but by chance there wasn't a tag on here a quick way to look at it to tell what side it goes on is look at the size of the pad on the brake shoe. If you see one it goes here to here. If you look at this shoe it goes all the way from here to here. This is a longer pad, this is a shorter pad. The shorter pad is the primary shoe and that will always face the front of the trailer.

With that known you can see that this is passenger side or right hand side for the trailer. These brake shoes are lined with an automotive grade friction material, this friction material is fully bonded, its not riveted to the shoes. Gives a lot longer life, more braking torque. The pad that's on here has a nice tapered edge on each end. Some brake assemblies they just cut it off and there's a sharp edge. They actually taper it on both ends and then they do a circular grinding on the pad to prevent cracking and crumbling that can lead to mechanical lock up. This is a manual adjustment brake, so it does require periodic manually adjusting of it.

The adjustment gear right here, this is where you would adjust your brakes. This one's nice because it has a fine tooth brake adjustment gear, because of that it allows for a more precise adjustment. There is no break-in period needed following your initial adjustment. If you notice on the very bottom of the brake assembly there's two adjuster plugs already in there. Those are nice because you can pop those out, put your tool in there to do your adjustment. You do want to have adjuster plugs in there because if those holes are left open, you're going to get dirt in there and you don't want that in your braking system. Some brake assemblies you buy do not put plugs in there so this is a nice feature because they do put the plugs in there for you. If you noticed the backing plate has the nice Dacromet coating on it, as you can see it is designed to fit a 4 bolt brake mounting flange. The mounting bolts are all installed in it, it does require nuts and lock washers to install onto your brake mounting flange. We do sell those separately on our website. This assembly is certified by US SAE standards and CSA standards, which are the Canadian standards. Again, the dimensions on it is 10" by 2-1/4". It is designed for 3,500lb axles. You can use the 10" brake drums with this. That should do it for the review of the 10" Uni-Servo Free Backing Hydraulic Trailer Brake Assembly for 3,500lb axles, this is the right hand passenger side, with the Dacromet finish.

Perfect fit and simple to install. Pre installed studs are a great idea however the 4 nuts for those studs should be included as well. Also there is no hole to plumb a break flusher into if your trailer has one. Couple minor things but I still am extremely happy with the purchase. 697663

Stripping down a 16 year old 21 ft. salt water use trailer - from end to end. The folks @ etrailer were very knowledgeable, and helpful in my decision making.

Other distributors could learn from these people; in regards to customer service, following up, both office and warehouse. Unloaded the products last night, nothing short, all quality in regards to their products, with great pricing.

I cannot comment on it's performance, although I am sure that the brake assembly will work better than it's predecessor. Order the washer/nut kit as well, it is less than two dollars. One of my old ones actually broke and I had to put a good amount of heat on the other three to get them off. The adjustment screw was easy enough to move the brakes in as well. I will be ordering the left side brake assembly tomorrow. 317252

I used new mounting hardware BIK-00 and installed the new units without any issues. I did bleed the lines and cylinders, and the brakes really didn't need more then a few clicks to adjust, best the brakes have every worked since I owned the camper, I am the second owner. I also replaced the hitch coupler / master cylinder with a new unit from etrailer AT82543, Jayco used 4 bolts to secure it, super easy to change. Parts arrived when expected and in great condition!

The fit of these was perfect. My trailer is a 2002 so it had seen quite a few miles since it was new and I can't imagine the brakes were ever replaced given the condition. I highly recommend purchasing the hardware that goes with this and reading the instructions on proper adjustment. Along with a new actuator this has my trailer braking like new! 387328

  • Replacement Boat Trailer Brakes Rated for 3,500 lbs
  • Thank you for that info and I definitely recommend replacing your boat trailer's brakes and we have exactly what you need. Based on the Dexter 8-247 number you gave we know you have a 3,500 lb Dexter 10" Hub and Drum Assembly such as part # 84546UC3. For a hub and drum that size the best option is the Hydraulic Trailer Brake - Dacromet because they are designed for marine applications with their corrosion-resistant dacromet coating and mount to a 4-bolt mounting flange such as # 4-35....

  • Recommended Brake Actuator With Lock Out for 7000 LBS. Boat Trailer
  • The standard tongue weight on a trailer is approximately 10-15 percent of the GTW. On a boat trailer it generally stays at 10 percent because most of the weight of a boat is towards the back end of the trailer, reducing the need for more tongue weight. This is why all of our couplers have a tongue weight of 10 percent of the GTW. If you'd like to be more definite in your tongue weight, you can always use a scale like the Sherline Trailer Tongue Weight Scale # 5780. The Titan Zinc-Plated...

For complete brake assemblies that fit this hub and drum I recommend the free-backing etrailer brakes # AKFBBRK-35L for the left side and # AKFBBRK-35R for the right side. If this is going on a boat trailer I recommend # AKFBBRK-35L-D for the left and # AKFBBRK-35R-D for the right. These brakes have a corrosion resistant dacromet coating ideal for marine applications.

I would recommend a 10 inch brake assembly that is free-backing like the part # AKFBBRK-35R-D for the right hand side and part # AKFBBRK-35L-D for the left hand side. These are also Dacromet coated to fight corrosion which would be a great option for you since your trailer is a boat trailer.

  • Replacement Brake Assemblies for Escort Boat Trailer
  • You need to measure the inside portion of your hub drum. You need the width and depth like in the picture I attached. I can almost guarantee that you have 10 inch assemblies based on the 4 bolt mounting pattern though. So for free backing assemblies you would want the part # AKFBBRK-35R-D for the right hand side and part # AKUBRK-35L-D for the left.

The # AKFBBRK-35R-D and # AKFBBRK-35L-D brakes you've selected are for 3,500 pounds axles with a 4 bolt brake flange. For a tandem axle brake line kit you can use # DM5428.

  • Recommended 10-Inch Brake Assembly With Aluminum Wheel Cylinder
  • We have just what you are looking for. The brake I recommend is part # AKFBBRK-35L-D. This is a 10-inch brake assembly that is 2-1/4 inches thick and has an aluminum wheel cylinder. This assembly is designed for 3,500-lb axles and will work with 13, 14, and 15-inch wheels and it has a 4-bolt brake flange mounting pattern. This assembly is for the left hand(driver side) of the trailer. The brake assembly for the right hand(passenger side) is part # AKFBBRK-35R-D.
