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.


Self-Adjusting Brakes Don't Require Routine Maintenance

With standard electric brake assemblies, you need to manually adjust them every now and then to make sure you're getting the shortest stopping distance 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

Dexter invests a lot of resources to ensure that these brakes meet the requirements for certification set by the Canadian Standards Association (CSA). Basically, a CSA certification tells you that these trailer brakes are well built and safe for use on the road.


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.

  • Will the Dexter 23-105-106-09 Fit AL-KO 5200k Axles
    The AL-KO brakes can have a few different mounting patterns, so I recommend measuring to double check. I included a picture of how the Dexter # 23-458-459 will measure to compare as well. Odds are these are correct, but it never hurts to double check. If it does end up being different, let me know what measurements you get and I can see what I have available for you.

  • Replacement Electric Brakes for Dexter PR-FF SEC-FF 5.2KPR-GGSEC-GG 12X2XQ 36-89
    Based on the photo and information you provided, I can tell you have 12 x 2 inch Dexter brake assemblies for 5.2K axles, for which the Electric Trailer Brake Kit # AKEBRK-7-SA will be an excellent replacement. These are self-adjusting brakes so they do not require periodic manual adjustment like standard brakes. To replace the original brake mounting bolts, nuts and lockwashers, you can use # BRKH12.

  • How to Pick Out Brakes for 3,500 lb Boat Trailer with Tandem Axles
    Installing brakes on a trailer really isn't too bad. The install is pretty basic and a DIYer like yourself wouldn't have a problem at all. To determine the parts you need though we need to for sure know what axles/spindles you have so that we pick out the right parts. I attached a couple guides for that down below for you to check out. There are a lot of boat trailers that have great results with electric drum brakes so if that's a route you are interested in that's what I would recommend...

  • Replacement Brakes for 2022 Keystone Cougar 316RLS
    Hey Rick! The correct replacement brakes are the Dexter Nev-R-Adjust Electric Trailer Brakes # 23-458-459. When you say rotors do you mean the hub and drum assembly? If that is correct, I will need some additional information to find the right hub and drum assembly. Can you tell me your current bolt pattern (it is either 6 on 5-1/2 or 8 on 6-1/2) and send me serial number off your axle tag? The grease seal varies within the same axle capacity so that is the only way to be sure. If you can...

  • When Do I Replace The Brake Assemblies On My 2013 Heartland Bighorn 3010RE
    Hello William. The Dexter 6K brake assemblies will come from the factory with a 3/16" thick brake shoe. Dexter recommends replacing them at 1/16" thick. So, you may not necessarily need to replace them now, but if not now, you will soon. If you want to replace the shoes only, I would need you to confirm exactly what brakes you have now. basically I just need to know if they are self-adjust or manual adjust. If there is a sticker or model number on the backing plate I should be able to cross...

    Hey Steve, Thank you for that information you provided, it sets me up to get you the direct replacements. For that replacement brake assembly you will want to go with the Dexter Nev-R-Adjust Brakes # 23-458-459.

    They sure will Thomas. The Dexter Nev-R-Adjust Electric Trailer Brakes - 12" - Left/Right Hand Assemblies item # 23-458-459 are exactly what you need for your 5,200 lbs axles.

  • Upgrading Axle on 2026 Keystone Cougar 260MLE
    Hi Gary; the highest capacity we have that matches your current axle length is 6,000 lbs. The Dexter Trailer Axle Beam with E-Z Lube Spindles - 86-1/2" Long # 8327826 will work as a replacement. Since the spring center measurement is slightly different you will also need to cut off the spring seats and weld on # TRSS300 to match your 68-1/2" measurement. If you want brakes as well you can use the # 23-458-459.

  • Replacing Warner 12 Inch Electric Brakes & 6 Bolt Mounting Flange
    So you'd have to change out everything, including the brake mounting flange, as the 6-bolt is simply not used anymore. There isn't a direct replacement from Dexter, so you'd need a 5-bolt brake mounting flange welded on (assuming you have a 3" diameter axle, which you should though you'll want to verify), the brakes, and a new hub and drum. The flange and brakes are the following: - Brake Mounting Flange for 3" Round Axle # 4-44-1 - Dexter Electric Trailer Brake Kit - 12" - 6,000 lbs...

  • Which Electric Drum Brakes for Dexter Nev-R-Lube Axle 410980-02 Hub 8-388
    I sent this to Dexter and this is what they sent back: I checked the number and it not a good hub number, and wheel tried pulls up 3,500 sprung axle from 2006 that doesn’t use a Nev-R-Lube hub. I would ask for confirmation on the number or some pictures of the product to confirm replacement parts that will work. If you can get me the info on your hub I can go from there. Look for a number on the outside of the drum.

  • Will Switching From a Drop Axle to a Straight Axle Increase Tire Clearance
    The 175/80-13 tire that you have now is 24" diameter x 6.9" wide and the new 225/75-15 tire is 28.3" diameter x 8.9" wide. Therefore, the new tire size will be 4.3" larger in overall diameter and 2" larger in overall width. However, you will only need to account for half of each measurement so 2.15" for diameter and 1" for width. The conversion from the 4" drop axle you have now to a straight axle is actually going to bring the spindle down in line with the axle which means you are actually...

    The 7K Dexter Nev-R-Adjust Electric Trailer Brakes, which comes in a set with both the Left Hand and Right Hand assemblies included as part # 23-464-465, can certainly be installed on your 6K axle assuming its 5 bolt pattern matches your existing flanges. In terms of size and bolt pattern these are indeed interchangeable with the Dexter 6K # 23-458-459. You are correct that the difference between the two sets just comes in their braking strength since they are meant to stop different...

  • Replacement Braking Assemblies for a 2014 Dutchmen Denali Trailer
    The best option for you is going to be to crawl under the trailer and read the tag on the center of the axle. This will tell you the weight capacity of your axle which will be needed to find the correct replacement braking assembly. I can see from the photo that you attached that your trailer uses a five bolt braking mounting flange therefore, it likely has either 6,000 lb or 7,000 lb axles. This would also make sense since you have a 3" diameter axle tube. The 4,400 lb axle capacity you...

  • Can 2016 Keystone Cougar 29RLI Be Upgraded to Use 6K Trailer Axles
    Hey Dave, thanks for reaching out. Before replacing everything, I recommend checking to make sure you didn't overload that one side of your rig and that your hub on that side of the axle is in good shape as those can cause weird tire tread wear as well. You could get away with 6K axles, but you'd want to stick with lower rated springs to avoid a stiff ride. The other thing to note is that using higher rated axles won't increase your weight rating either. From what I'm seeing on your...
