Reverse Easily with Free-Backing Brakes

Backing up your trailer might be the only time you don't want the brakes to work. Normally, this would be a job for the reverse lockout on your hydraulic actuator. But if you don't have a lockout, you'll need brakes that will you allow you to back up freely instead.


How do they work, you ask?


A close-up shot of a hydraulic drum brake shows the components of the assembly.

During normal forward braking, a fall-away shoe expands to catch your brake drum with enough force to bring your rig to a stop. When driving in reverse, however, these brake assemblies prevent the shoes from fully catching on the drums. This takes away your braking control, allowing the wheels to continue to turn.


Note: Free backing brakes don't activate when you're in reverse. So, keep in mind that a trailer breakaway kit will not be effective if your trailer were to disconnect from your tow vehicle while you're backing up.


Automotive-Grade Friction Material

The pads on these trailer brakes are made of the same friction material that you might find on a car's drum brakes. In fact, the material is SAE-N certified. So, not only does it provide high-performance braking, but it's environmentally friendly, too! With these brakes, your trailer will be good to go on any road throughout the United States and Canada.


The superior quality of these pads is also due to the fact that they're bonded to the shoes, not just nailed down. Riveted brake pads will always give you a screeching reminder to replace your brake shoes. That's because the rivets will scrape against your drum as the friction material wears down. You won't have that noisy problem with bonded brake pads. You'll also get a little more friction pad contact because there aren't any cutouts for rivets. And more friction means more stopping power.


A close-up shot of a drum brake shows a tapered brake pad.

These pads are also tapered, which should help to prevent any broken, crumbly bits of material from rotating inside the drum as the pads wear over time. Brakes without these tapers are more likely to create a jarring braking experience that could cause the brakes to stutter and lock up.


Thoroughly Tested for Safety

A lot of resources have been invested to ensure that these brake assemblies meet the requirements for certification set by the QAI and CSA . Basically, these certifications tell you that these trailer brakes are well built and safe for use on the road. They've been tested for braking performance under real-world conditions to provide the most realistic scenario for the everyday tower.


How to Manually Adjust Trailer Brakes

The more miles you put on your trailer, the more your brake pads will wear down. As they lose contact with the drum, stopping distances get longer and longer. To keep your brakes working great, it's important to adjust them pretty routinely. For this job, grab a floor jack and either a brake adjustment tool (sold separately) or just a standard flathead screwdriver.


Jack up your trailer enough to get the wheel(s) off the ground. Remove the adjuster plugs from the backing plate on the brake, and insert the flat end of the tool through the back of the assembly.


Screenshot from an instruction video shows how to manually adjust the alignment on a drum brake

Push in on the star gear and lift it up. Keep doing this until the brake pads catch on your brake drum. When you can't spin your wheel by hand anymore, back the gear off by about 10 clicks (push down on the star gear). Does the wheel now spin freely (even if it sounds like the brake pads drag slightly on the drum)? Great! Then you're all done with that one and ready to adjust the rest.


How to Break In New Brakes

Once you get these assemblies installed, and your lines flushed with fresh fluid, you'll need to break in these brakes. First, find a long stretch of road or a big, empty parking lot. Speed up to about 40 mph and brake to slow to about 20 mph. Repeat this 15-30 times. The goal is to get the brake shoes properly seated into your drum. You'll know you've done that when it feels less jerky (and more consistent) each time you apply the brakes.


Note: The brakes will be very hot after doing this, so after every 10 stops you'll want to wait about 10 minutes to let the brakes cool off before continuing. If you don't, you might cook and crack the pad material.

  • Recommended Electric Over Hydraulic Conversion for Dutchmen Voltage 3818 Toy Hauler Triple Axle
    We do have the ability to convert your Dutchmen Voltage 3818 to Electric over Hydraulic brakes. First you will want the brake assemblies and for those, I recommend the Hydraulic Brake Kit - Uni-Servo - Free Backing - 12" - Left/Right Hand Assemblies - 5.5K to 7K # AKFBBRK-7 (one kit per axle). Then you will need brake lines like the Deluxe Hydraulic Line Kit - Tandem Axle - Drum # 9579-2 along with the Hydraulic Line Kit, 3rd Axle - Drum and Disc # 9579-01. Then I recommend the HydraStar...

    For your conversion to hydraulic brakes on your 7,000 lb dual axle RV, I recommend the Hydraulic Brake Kit - Uni-Servo - Free Backing - 12" - Left/Right Hand Assemblies - 5.5K to 7K # AKFBBRK-7. These assemblies are side specific and are labeled for you. These will work with your current hub and drum assemblies. For installation and adjustment, you will want the Brake Adjustment Spoon for Drum Brakes # W80630. If you need the mounting bolts for these assemblies, I recommend # BRKH12. If...

  • How to Find Replacement Drum Brake Assembly for Boat Trailer
    I can tell you exactly how to find compatible drum brake assemblies, though I took a look and could not find any type of reference to Dico 40511. To determine the brake assemblies that will fit your 2002 Escort boat trailer, you need to know your axle's weight capacity, your mounting flange bolt pattern and the inside diameter and depth of your drum. For example, Hydraulic Brake Kit # AKFBBRK-35-D are rated for 3,500 lb axles, have a 4-bolt mounting flange pattern and measure 10" diameter...

  • Parts Needed to Change a Triple Axle Kaufman Trailer from Electric to Electric Over Hydraulic Brakes
    To change your electric brakes on your Kaufman trailer to an electric over hydraulic (EOH) system you will need to hydraulic brakes, brake lines, an EOH actuator, a breakaway kit (which you should already have), and a brake controller (which you should already have). I highly recommend going with the HydraStar EOH Actuator # HBA-12 which is one of the best options out there and has received great reviews from other customers. We hardly ever see any troubleshooting questions about these...

  • Adding Electric Over Hydraulic Drum Brakes to a Trailer
    With 6,000 pound axles they must take 12 x 2 inch assemblies. For a left and right side pair of assemblies you can use # AKFBBRK-7. We do not have an option for self-adjusting brakes in this size with a single-servo design. For an actuator I recommend the Hydrastar # HS381-9066. This unit is rated to 1,200 psi so it provides a little extra kick above the 1,000 psi units. Since you have a couple of 6,000 pound axles you're going to want the best to slow the loaded trailer down. It also...

  • Replacement Brake Assemblies and Brake Line for 3,500 Hydraulic Trailer Brakes
    Do you by chance have a 3,500 ALKO axle 8500? Or an 8,500 lb axle? I believe you'd have the 3,500 lb axle but wanted to be sure. For 3,500 assemblies you'd want the part # AKFBBRK-35-D as replacing all of the individual parts you mentioned would end up costing more and be more labor intensive. For a brake line kit then we have the part # 9504 which would fit and work well.

  • Replacement Recommendation for Dexter Axle 8-201 Hub Assembly on Older Horse Trailer
    We've got you covered! To replace your wheel bolts you need the Dexter Wheel Bolt # 7-262 which is a 1/2" diameter and 2-11/16" long. Since your hub and drum assembly looks to be pretty worn though I recommend just replacing the whole thing so you have completely new bearings and a seal as well. To replace the whole drum assembly you'll need part # 8-201-5UC3-EZ. The bearings that come with this kit match your application (I checked with my contact at Dexter Axle) but you will want to...

    For your AL-KO 7210 braking assembly, you can use the Hydraulic Brake Kit # AKFBBRK-7 as a replacement. These braking assemblies measure 12" x 2", bolts onto a 5 bolt mounting flange, will work with wheel sizes from 14-1/2" to 16-1/2", and has maximum axle ratings of 5,200 lbs, 6,000 lbs, and 7,000 lbs. You're also going to need the mounting hardware # BRKH12, and the adjustment spoon # W80630. Also, for your grease seal 22333 KBN, you can use the Grease Seal # GS-2250DL.

  • Recommended Replacement Surge Coupler for ATWOOD 82541 and Brake Assemblies
    The Atwood 82541 you referenced was discontinued a while back. The replacement I recommend is the Brake Actuator with Manual Lockout - Bolt On - Drum - 2" Ball - 7,500 lbs # T63FR. Then for your EZLoader drum brakes I recommend the Hydraulic Trailer Brake Kit - Uni-Servo - Dacromet # AKUBRK-35-D if you have 10 inch drums or the Hydraulic Brake Kit - Uni-Servo - Free Backing # AKFBBRK-7 for 12 inch drums.

  • Replacement Brakes and Hub/Drum Assembly for Eagle Boat Trailer With 6k Axle
    Thank you for providing that information. Since you have a 6,000 lb axle we can narrow down the parts. However, you will still need to identify your grease seal. Unfortunately, the serial number won't help in this case since Axis Products, Inc. was sold in 2015 so no information is available. For brakes you can use the # AKEBRK-7-SA if you need electric brakes or the # AKFBBRK-7 for hydraulic brakes.

  • Is It Better To Replace 12 x 2 Trailer Brake Shoes Or Replace The Entire Assembly?
    The difference between the Titan Replacement Brake Shoes # T4798400 and # T4807700 is which brake assemblies the kits fit on. The # T4798400 fits brake assemblies # T4489600-500 where the # T4807700 fits discontinued braking assemblies T4203000. Both of the kits are per wheel and in general there is not a large cost difference between the replacement shoes and complete replacement braking assemblies. Due to that we recommend going ahead and replacing the entire braking assemblies using...

  • Replacement Hub and Drum Assembly for 2006 Karavan Trailer
    You already did all of the work here by finding the bearings. Since you have a # 25580 inner and # 15123 outer bearing the Easy Grease Trailer Hub and Drum Assembly for 6K Axles # AKHD-655-6-G-EZ-K will work as a replacement. The only other thing to match up is the bolt pattern and this has the same 6 on 5-1/2 you currently have. If you want replacement brakes as well you can use the # AKUBRK-7. If you don't have a lockout and need free backing brakes then we also have the # AKFBBRK-7.

  • Solution for Manually Locking Out Brakes on Actuator With Electric Lockout
    If you have an actuator like the Dexter # T4750620 you looked at, the only way to lockout the brakes is with the electric lockout. If you have a different model it is possible it has a spot for a key on the side like the # DX94FR which would work with an actuator like the # DX56FR. If you do not have this, there is still a solution for your problem. Although you can't manually lockout the actuator, you could add free-backing brakes to your trailer. These eliminate the need for the lockout...

  • 12" Hydraulic Brake Replacement for Karavan US-4100-78-SSB-ST Trailer
    Based on my research, your Karavan US-4100-78-SSB-ST trailer uses standard 12" x 2" drums, so for a set of hydraulic brakes, I recommend the Hydraulic Brake Kit - Uni-Servo - Free Backing - 12" - Left/Right Hand Assemblies part # AKFBBRK-7 (black powder coat finish) or part # AKFBBRK-7-D (dacromet finish). These are compatible with 5,200 lb, 6,000 lb and 7,000 lb axles. For the mounting bolts and hardware, you can use part # BRKH12.

    Hey Tom thanks for your questions. To answer your first question, yes, you can use the # AKFBBRK-7 or the # 23-342-343 free backing hydraulic brake assemblies on your dump trailer. All of these use the same standard 12" x 2" brake shoes. If you are trying to decide between the Dexter brand or our etrailer brand, personally I recommend etrailer brand # AKFBBRK-7. In my experience they are pretty much identical to the dexter brand but for a fraction of the cost. Were it my trailer, I would...

For regular hub use part # AKIHUB-655-6-EZ-K but if you are wanting to incorporate brakes then you want hub and drum part # AKHD-655-6-EZ-K with the brakes # AKEBRK-7-SA for electric or # AKFBBRK-7 for hydraulic.
