Quick Tip: There's really not a whole lot to getting new drum brakes. If you've confirmed that all of the specs listed above line up with what you need for your trailer, you can be pretty sure these will work for you.


Automotive-Grade Brake Pads

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 closeup shot of an etrailer 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.


Self-Adjusting Brakes Don't Require Routine Maintenance

With typical electric brake assemblies, you need to manually adjust them every now and then to make sure you're getting the shortest stopping distances every time you tow.


A trailer drum brake with a red callout shows the location of a tension cable and pulley on a self-adjusting trailer brake.

With self-adjusting brakes, though, you'll always have peak stopping power - simple as that! As the brake pads wear over time, a tensioning cable will automatically keep the pads in alignment so they'll consistently make contact with your drum when you brake. You won't have to do tedious manual adjustments anymore.


Thoroughly Tested for Safety

A lot of resources have been invested to ensure that these brakes 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 Break In New Brakes

Once you get these brakes installed, you'll need to break them in. First, find a long stretch of road or a big, empty parking lot. Once you're there, set your brake controller to its maximum setting and get moving. 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 and magnet 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.

  • Replacement Brake Assemblies and Grease Seal for 3,500 lb Trailer Axle
    Hey Phillip, since we know you have 3,500 lb axles we can help but it's not based on the VIN. Since we don't know what brake assembly brand you have on your trailer but we do know capacity the correct replacement assemblies are the part # AKEBRK-35-SA. It's oftentimes more cost effective to just replace the assemblies instead of the individual components plus it's a lot harder to find the parts. Then for a grease seal you'd want the part # RG06-050.

  • Can I Add Electric Brakes To A 1993 EZ Loader Boat Trailer
    Hello Mike. It sounds like you are wanting to add electric brakes to your boat trailer that currently has no brakes. This is possible, but you will first need to make sure that your axle is equipped with a brake flange at the base of the spindle. The brake flange is necessary for adding brakes. If you do have a brake flange, you will next need to determine your bearing sizes. Electric brakes will require new hubs and drum assemblies, and we need to be sure that there is a drum available...

  • How to Determine Replacement Hub Assembly for PacWest Utility Trailer
    It looks like PacWest has a number of different utility trailers with different capacities. In order to determine if the # AKIHUB-550-35-K will fit you are going to need to identify your axle or check your bearings. Assuming you have a 3,500 lb axle, more than likely this will fit. You could check your axle tag for identification and call PacWest or you could use your VIN number. The other option is to pull off your existing hubs and see which bearings you have now. The part number is...

  • Troubleshooting Trailer Brakes That are Still Weak After Adjusting
    Interesting situation you've got, Steve. Typically weak bakes are a sign that the brakes need to be adjusted, but since you've already done that, It makes me think that maybe the brake controller is not putting out enough voltage. To check, you'll need to turn the gain all the way up then test the brake output pin on the vehicle side connector using a multimeter # PT89ZR while someone applies the manual override on full. You should be getting 12v, but if you're not then there is an issue...

  • Replacement Trailer Brake Assembly Recommendation for Trailer with EZ Lube 3500 Axles
    If you have a 3,500 lb Dexter EZ Lube spindle we for sure have the parts needed to add brakes to your trailer or replace ones that you currently have. For a set of 10 inch assemblies that would fit and work well you'd want the part # AKEBRK-35-SA which will fit both sides and work well. If you have something different going on email me back and I'll help you further.

  • How To Use Jeep Wheels With Timbren Axle-Less Trailer Suspension System
    In order to use Jeep wheels with the Timbren Axle-Less Trailer Suspension System you'll need to go with the part # ASR1THDS03 which has a 2,200 lb weight capacity. This can then be used with the Trailer Idler Hub Assembly part # AKIHUB-550-35-EZ-K or the Trailer Hub and Drum Assembly part # AKHD-550-35-EZ-K and Electric Trailer Brake Kit part # AKEBRK-35-SA if you need brakes. This will give you a 5 on 5" bolt pattern to use the Jeep wheels as well as the lift and offset needed for clearance.

  • Changing from 10 x 1-3/4
    I do have an option for you but we no longer carry 10 x 1-3/4" brake assemblies. I recommend upgrading to 10 x 2-1/4" brakes as this is the more common size for 3,500 lb axles and will provide greater stopping power. For a set of 10 x 2-1/4" brakes, I recommend taking a look at the Electric Trailer Brake Kit part # AKEBRK-35-SA. These brakes are self-adjusting and use a 4 bolt brake mounting flange which is what should be equipped on your AL-KO axles. If you have a different brake mounting...

  • Replacement 3500 lb Hub/Drum for TruRyde RVD-H-65535 10 Inch Trailer Brake Drum
    The hub you describe is a 3500 lb 10 inch hub/drum with a 6 on 5-1/2 inch bolt pattern which uses an L44649 outer and an L68149 inner wheel bearing and a 58846 grease seal. For a replacement, I'd recommend the # AKHD-655-35-EZ-K hub/drum. The hub/drum includes the inner and outer bearings, races, the grease seal, dust caps for both EZ Lube and standard spindles as well as lug nuts. The hubs are pre-packed with grease. For replacement brake assemblies, I'd go with # AKEBRK-35-SA self-adjusting...

  • How To Determine If Boat Trailer has 10 Inch or 12 Inch Brake Assemblies
    When determining if you need 10 inch or 12 inch brake assemblies there are a couple of easy things to check to confirm the fit for your trailer. The first thing is you can measure the diameter of your hub. The second thing is you can look at the brake flange, if it has 4 bolts then it is 10 inch if it has 5 then it is 12 inch. Because you know you have a #84 spindle we can be confident that you have a 3,500 lb axle and you will need the 10 inch assemblies. I recommend the Hydraulic...

  • Parts Needed to Add Brakes to 3,500 lb Trailer Axle
    Since we know you have 3,500 lb axles we can pretty easily pick out the correct parts you'd need to add brakes to your trailer. You'd need new hubs that have integrated drums like with the part # AKHD-545-35-EZ-K which have the very common 5 on 4-1/2 inch bolt pattern. Then you'd need to add matching brake assemblies with the part # AKEBRK-35-SA and you'd be set aside from 10 gauge wiring like part # 10-1-1 which we offer that you'd want to wire up the assemblies with. This is sold by the foot.

  • What Ohms Should Trailer Brake Magnets Be?
    Assuming that when you tested the resistance of the brakes you were testing the two wires on each magnet and getting 2.0 and 2.8 ohms the magnets on your trailer are not working correctly and will need to be replaced. For 7" brakes you should get 3.8-4.0 ohms, and for 10-12" brakes you should have 3.0-3.8 ohms. If the brake shoes themselves are good you can replace just the magnet using 7" # AKBRKR-M7, 10" # AKBRKR-M10, or 12" # AKBRKR-M12. If the shoes are needing replacement as well...

  • Determining Correct Replacement Brake and Hub Assemblies for 2017 Karavan Boat Trailer
    In order to find the correct replacement electric brake assemblies for your boat trailer, you will want to first measure the depth and diameter of your drums (or just measure your existing brakes).

    To find the correct replacement brakes you will need to identify your axle capacity. Based on the specs of the trailer I'm sure you have a 3,500 lb or 4,400 lb axle. The Dexter Nev-R-Adjust Electric Trailer Brakes # K23-462-463-00 you looked at will work if you have the 4,400 lb axle. If you have a 3,500 lb axle you can use the # AKEBRK-35-SA or if you want to stick with Dexter the # 23-468-469.
