Great service from etrailer, very fast shipping!



by:

EASY INSTALL COMPARED TO REBUILDING EXISTING BRAKES, ALSO SELF ADJUST WILL SAVE ME SOME MAINTENANCE TIME SINCE WE PUT ON UP TO 8K MILES A YEAR WHICH NORMALLY REQUIRES SEVERAL AJUSTMENTS OF OLD BRAKES TO KEEP THEM WORKING UP TO PAR



by:

The brakes fit perfectly. Have not tried them yet, but they appear to be of good quality. I really want to comment on how great the service has been through the ordering process. The parts arrived even quicker than I had been told they would. When I called for technical assistance while installing them (for torque numbers), I was immediately connected to someone who could answer my questions. This is the second time I have ordered from them, and will not hesitate to do so again.



by:

These new brakes worked perfect with my 6k axles. I will be placing another order soon for the dust caps. Thanks for a quality product at a reasonable price.



by:

I got this to replace the brakes on my horse trailer and they worked great!! Easy to install after taking the hubs off just remove 5 nuts bolt new assembly on. That easy. This is the 2nd set I have gotten I did a friends horse trailer last year and they love it. Thanks Etrailer!!!!!



by:

I ordered a set of four for my tandem axle trailer on a Friday and they arrived on Wednesday. They were Incredibly easy to install! The bolts lined up perfectly, and from start to finish took about two hours, that included repacking the bearings. Best pat is the, MADE IN USA label I am very very pleased so far. I cant wait to try them out and see if the automatic adjustment works. Thanks etrailer!!



by:

This brake backing plate fits the ALKO axle on my Keystone trailer. Bolt holes align exactly. I ordered three more to replace all of the problematic OEM ALKO brakes which shuddered and squealed since new.

  • Recommended Suspension Upgrade for Grand Design 17MKE Travel Trailer
    Since your Grand Design 17MKE has a GVWR of 6,395 lbs, you more than likely have 3,500 lb axles. That being the case, the Roadmaster Comfort Ride Leaf Spring Suspension Kit # RM-2460-2560 will not fit your travel trailer. Although Roadmaster does not have a kit like this for 3,500 lb axles, I do have another option. I recommend the Roadmaster Comfort Ride Shock Absorbers for Tandem Axle Trailers # RM-2450 which are designed for 3,500 lb axles. Your trailer will need to have the leaf springs...

  • What Is The Difference Between the 6K and 7K Dexter Axle Electric Brake Assemblies
    You are correct, the difference between the Electric Brake Assembly for 6K Axles, part # 23-458 / 23-459 and the Electric Brake Assembly for 7K axles, part # 23-180 / # 23-181, is that the 7K brake assembly has a stronger magnet, and also has a different compound on the brake shoes than the 6K electric brake assemblies for more stopping power. Both the 6k and 7K brake assemblies, fit the same axle. Yes, the 7K backing plates on part # 23-180 / 23-181, will fit on 6K pound axles.

  • Do Nev-R-Adjust Brakes and Self-Adjusting Brakes Work the Same Way
    Nev-R-Adjust is Dexter's specific trade name for self-adjusting brakes like # 23-458 and # AKEBRK-7L-SA. Self-adjust and Nev-R-Adjust are the same type of brakes. After their initial adjustment both will automatically maintain correct braking pressure. With self-adjusting brakes, the brake shoes are always properly aligned, so there's no need to manually adjust the brakes after the initial adjustment. As a result, you get optimum performance without having to take the time to continually...

  • When Do Brakes Need to be Added to Both Axles of Tandem Axle Trailer
    There really isn't a particular maximum trailer weight that is used to determine when brakes need to be added to both axles of a tandem axle setup. While I do still recommend checking your local laws, I am also not aware of any general laws that indicate when brakes need to be put on all axles of a multi axle trailer (only laws that state when a trailer needs to be equipped with them). With all of this in mind, we always recommend adding brakes to both axles of a tandem axle trailer....

  • Troubleshooting Weak Brakes on 2008 Everest After Having Bearings Repacked
    Either they somehow got grease on your brakes and they aren't working because of that or the brakes are way out of adjustment. Are the brakes manual adjust or self -adjust? If they are self adjust they should start working again after a several brake applications while moving. If they are manual adjust you'd want to click the star wheel of the assemblies until you feel a light drag as you turn the wheel by hand. Either way though I'd recommend speaking with the shop you had work on the...

  • Initial Adjustment Of Nev-R-Adjust Electric Brakes
    When you install Nev-R-Adjust drum brakes like Dexter part # 23-458 and part # 23-459 the initial setup will be different. The Nev-R-Adjust has a small lever that prevents the brake star wheel from backing off as you do when you adjust standard brakes. With the Nev-R-Adjust brakes, you simply turn the wheel backwards after everything is installed, until you get a slight drag. If you continue turning the wheel it would keep adjusting the brakes until it locks the wheel. You would then...

  • Do Dexter Nev-R-Lube Hubs Require Greasing Spindle
    Hey Christopher, when installing hubs that have Nev R Lube bearing setups there is no initial grease required. Since it's totally sealed it would be pointless to do this.

  • Replacement Brakes And Drums For A 2022 Rockwood Signature Ultra Light 5th Wheel
    Hi Carl! While I couldn't find what bearing combination comes on your 2022 Rockwood Signature Ultra Light 5th wheel, the 5,200 pound capacity did help me narrow it down. You will either need to pull a hub off to see what you have or contact Rockwood with your Vin to have them tell you. I have the options listed below with the corresponding bolt pattern. 6 on 5-1/2" Bolt Pattern: -Inner bearing: 25580 + Outer bearing: 15123 - etrailer Easy Grease Trailer Hub and Drum Assembly for 5.2K...

  • Are 12"x2" Left Hand Brake Assemblies Available?
    Hi Robert! Single assemblies can be somewhat difficult to find on our website, but I have Dexter and etrailer options listed below. All are 12" x 2" left side electric brake assemblies, but the first set are manual adjusting and the second set are self adjusting. You didn't mention which style you were looking for, so I figured I would include both. Manual Adjust: Dexter Electric Trailer Brake Assembly - 12" - Left Hand - 6,000 lbs # 23-105 Dexter Electric Trailer Brake Assembly - 12"...

  • Which is Best Brand of Trailer Brake Assemblies
    Dexter brand trailer axle components are considered by most people to be the highest quality around. Whenever possible I recommend them over the other brands. For 12 inch diameter Dexter brake assemblies that are self-adjusting the Dexter kit part # 23-458 for the left hand side and part # 23-459 would be what I'd recommend.

  • Recommended Axles For Travel Trailer With 68-1/4 Inch Spring Center To Spring Center Measurement
    You do have some odd measurements. You can absolutely use the parts that you mentioned and drastically change all of your trailer connection points (Plan A), however, I recommend doing something much easier and cleaner. It won't require finding new connection points for your springs, building outer wells, or adding different springs. So consider this Plan B. We have the Timbren Heavy-Duty Axle-Less Trailer Suspension - 4" Lift Spindle - Off-Road Tires - 3,500 lbs # ASR35HDS02. This...

  • What Brake Replacements Do You Recommend for My Dexter 5200 Pound Axles?
    For a great option of Nev-R-Adjust brakes on your 1999 Jayco Designed 5th-wheel trailer, I recommend the Dexter Nev-R-Adjust Electric Trailer Brake Assembly - 12" - Right Hand # 23-459 along with the Dexter Nev-R-Adjust Electric Trailer Brake Assembly - 12" - Left Hand # 23-458. Both of these brakes have a 6,000-pound capacity and will have enough weight capacity for your 5200 pound axles. If you need the hub-and-drum assembly along with the brakes, the ones you need depend on the lug...

  • How To Break In Self Adjusting Dexter Brakes On Horse Trailer
    Since the Dexter 12” self-adjusting brakes part # 23-459 and part # 23-458 are brand new and the braking is weak there is a chance the brakes are not fully adjusted yet. The brake assemblies haven't been activated enough times for them to find the right setting. I would not manually adjust the brakes anymore instead keep testing the brakes by driving around 15-20 MPH on a flat surface (like a parking lot) and hitting the brakes or use the manual override on your brake controller.

  • Replacement Bearings, Hubs, and Brakes For Dexter Axle On 2019 Jayco Eagle 25.5REOK 5TH Wheel Camper
    Your Dexter axle needs the Bearing Kit # BK3-300 to fit the Hub # K08-201-98 that came on your axles. We do have the Dexter Nev-R-Adjust Electric Trailer Brake Kit # 23-458-459 if you are needing to replace the assemblies. They are also available separately Right # 23-459 and Left # 23-458 or as just the Right Shoes # K71-676 and Left Shoes # K71-675. I recommend the Seal Puller # PTW1219 and Install Set # PTW83020 to make changing the bearings and races easier.

  • Should 7k Trailer Brake Assemblies be Used on a 6k Trailer Axle
    Dimensionally they'll fit and they will operate but you don't actually get a stronger braking action. Instead the brakes will be harder to setup and get the correct amount of braking action. The heavier duty assemblies have a magnet that's more sensitive which helps with heavier weights but when used on a lighter trailer they become harder to setup and not anymore powerful. Best option is go to with 6k brake assemblies like the part # 23-459 for the right hand side and part # 23-458 for...

  • Trailer Brake Magnets Not Making Full Contact with Inside of Brake Drum
    The brakes should still work fairly well. The magnets, when energized, cling to the armature surface of the drum and the rotations of the drum pull the magnet which then pushes out the shoes to make contact with the drum. If the brakes seem weak then you could adjust them out to be a little more aggressive to compensate for the little bit of the magnet not making contact with the drum. And if that still is not enough then you would need to replace the drums.

  • Replacement Trailer Brake Assemblies for part Number 023-357 as well as Replacement Seal 10-36
    The Dexter part number 023-357-00 is a 12x2 electric brake assembly. The correct RH assembly to use to replace what you have would be the part # 23-459 and for the LH assembly you would want the part # 23-458 if you have 6K axles. For 10-36 seals you then would want the part # RG06-070.

  • Can Hydraulic Trailer Brake Drums be Used with Electric Brakes
    Some drums can be used with hydraulic or electric brakes and others cannot. You would have to check with the drum manufacturer unless it specifically says on the drum somewhere. You mentioned a ridge which would indicate to me that you may not be able to use electric brakes with the hubs you have. The magnet does need a flat surface to attach to. This is called the armature surface. The less surface area there is on the armature surface the weaker the connection between the magnet and...

  • Does it Matter Which Trailer Brake Assembly is Right and Which is Left
    The braking performance will not be very good if you install brake assemblies on the wrong side of the trailer. The left side assembly is the driver's side (if the trailer were a car) and the right side is the passenger's side. The actuating arm that is attached to the brake magnet should be pointing towards the front of the trailer like in the picture I have included.

    For your 5,000lb axle, with a 12" brake assembly, you can use the: -Dexter Nev-R-Adjust Electric Trailer Brake Assembly # 23-458. Even thought this is stated to work for a 6K axle, it will work perfectly fine with your 5K axle. Should you want the left and right sides, you can use the Dexter Nev-R-Adjust Electric Trailer Brake Kit # 23-458-459. I have included a couple installation videos for you to check out as well.
