After a problem with a brake assembly I had purchased Ashley in customer service helped by sending me another brake assembly at my expense. She advised me to send the old one for a warranty inspection. After a few weeks the purchase price was refunded. They did stand behind their warranty and Ashley was very helpful. 570593

I was originally going to replace a brake magnet that came apart but quickly realized it was cheaper and less work to replace the entire brake assembly. Delivery of my new parts was very fast and came in a heavy duty box so everything was in great shape. I also ordered bearings and new grease seals. I e-mailed your company to ask which parts I needed and I received a very prompt reply with a list of everything I needed. I am a very satisfied customer and I will purchase from e-trailer again and also tell my fellow campers about the good and prompt service I received from your company. 559253

Did a remove and replace. Original Dexter Brake assemblies had curved wear and missing the brake adjusting plugs, getting dust and no doubt water in them from the Airstream plant in Jackson Center, OH. All EIGHT of eight wheels had them missing. That was my Problem. Now the Cure: etrailer had two Brake Assembly kits at my door three days after ordering. I installed them today and they work and had supplied five fresh locking bolts and the two plastic brake adjusting plugs. I am one happy Airstream trailer camper. First time doing brakes on a trailer and it was much easier doing the complete assembly. Will break them in as suggested in their installation instructions. I recommended etrailer.com on the Airforums.com that Airstream owners follow for information. One member already said he ordered parts, as he did not know how to find what he needed. Excellent service ordering from my computer. Notice of parts being shipped was emailed to me. Parts were dropped off at my doorstop. If the carton had some glazed doughnuts included... it would have been 5% better. George J.... you did me right as a first time customer. 554896

Ask the Experts about this Dexter Axle Accessories and Parts

  • New Nev-R-Adjust Brakes Seem Weaker than Old Brakes on 5th Wheel Trailer
    Nev-R-Adjust brakes such as # 23-459 do require an initial adjustment. If you made that initial adjustment you should be able to hear a slight but constant drag of the brake pads on the drum when the wheel is turned. If you do not hear that then they will need to be adjusted out more or they will eventually adjust out themselves. Driving forward is all you would have to do to get them to adjust themselves but it can take a while without the proper initial adjustment. You may also...

  • Dexter Brake Assembly Recommendations to Replace Part Number 023-357-00
    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. If you have 7k axles you would want part # 23-464 for the LH side and part # 23-465 for the RH side.

  • Why Are Dexter Trailer Brake Assemblies More Expensive
    The higher cost of Dexter electric brakes like the Nev-R-Adjust # 23-459 definitely has a lot to do with their name. The name is so recognizable in the industry because they have been around for a very long time, their parts are extremely reliable, and they are made right here in the USA. With that being said the more cost-efficient options we offer still do a great job. In fact our etrailer.com brake assemblies such as # AKEBRK-7L-SA for the Left Hand and # AKEBRK-7R-SA for the right...

  • Is there a Difference Between Dexter 6k and 7k Rated 12x2 Electric Brake Assemblies
    Actually for a 6k rated Dexter 12x2 brake assembly you would want the part # 23-459 for the right hand side and part # 23-458 for the left hand side. Then for a 7k rated assembly you would want part # 23-465 for the right hand side and part # 23-464 for the left hand side. The magnets are rated differently. That is the biggest difference.

  • 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 I Replace my Manual Brake Assembly with the Dexter Nev-R-Adjust Brake Assembly
    You will be able to use the Dexter Nev-R-Adjust Electric Assembly for 6,000 lbs. Axles # 23-459 for your trailer even though your axle is rated for 5,200 lbs. However, you are limited by the 5,200 lbs. capacity of your axles and cannot load 6,000 lbs. in your trailer because you installed this brake assembly. I do not recommend installing brake assemblies with two different ratings on your vehicle. While your trailer brakes will work, the Dexter manual adjust assembly # 23-181 rated...

  • Can Dexter Electric Drum Trailer Brakes Replace AL-KO Trailer Brakes
    We actually have 12 x 2 inch electric drum brake assemblies that are replacements for the AL-KO brake assemblies. Take a look at Hayes/AL-KO 12 x 2 Electric Brake Assembly, # 185150. This is the right hand assembly. The left hand assembly is # 185100. The Nev-R-Adjust Electric Brake Assembly, # 23-459, will fit provided that the bolt hole pattern on the brake mounting flange matches your existing set up. It should have a 5 on 3-7/8 inch bolt pattern, like flange # 4-44-1, to work.

  • Recommended Replacement Electric Trailer Brakes for Jamco 4 Horse Trailer
    To select replacement electric brake assemblies for your Jamco horse trailer you'll need to confirm a few details about your trailer set-up. First you need to confirm the axles' capacity to ensure your new brakes will have the required stopping power. Axles in Jamco horse trailers can be rated from 3500- to 8000-lbs. There should be a sticker on the axles that indicates the capacity. You also need to match up the size of the brakes, both their diameter and width, and confirm the mounting...

  • Do Dexter Nev-R-Adjust Trailer Brakes Automatically Adjust Going Forward or in Reverse
    The Dexter Nev-R-Adjust trailer brake assembly # 23-459 and matching left hand side # 23-458 adjust automatically when traveling. It does not matter if it is forward or reverse. When traveling and using the brakes they will automatically rotate an adjuster to adjust the lining out. There is an initial adjustment you will want to do though, otherwise it can take awhile for the brakes to adjust out when new. I have linked a video that explains this for you.

  • Do Self-Adjusting Trailer Brakes Require Reversing the Trailer for Adjustment
    Self-adjusting trailer brakes like the Axle Technology # AKEBRK-7L-SA and # AKEBRK-7R-SA do require an initial manual adjustment as you noted but after that they will automatically maintain the correct pad pressure with normal driving. The auto-adjust works whether you are driving in a forward direction or in a reverse direction. The automatic mechanism uses a fine-toothed gear that can make precise adjustments and saves you the hassle of re-adjustment after initial break-in.

  • Replacement Dexter 6K Electric Trailer Drum Brakes
    To replace your Dexter right-hand 6K electric drum brake 023-358-00 you can use part # 23-106-09. For a left-hand brake use part # 23-105-09. If you decide to replace both left and right brakes we offer both in a set as part # 23-105-106-09. These brakes fit both 4-bolt and 5-bolt brake mounting flanges. If you need mounting hardware you can use bolt # 7-5, lock washer # 38LW and nut # 38N.

  • Replacement Brake Assembly Availability for Rockwell Trailer Axle
    I looked up what Rockwell brake assemblies look like and found that they are the standard style of drum brake assemblies. Since you said you have a 5 lug mounting flange on your trailer most likely you need a 12 inch brake assembly like the part # 23-458 for the left hand side and part # 23-459 for the right hand side. These assemblies have the 5 lug mounting bolt pattern and are for 6k axles. If you need a different assembly check out the link I attached that will take you to a...

  • Are New Backing Plate Bolts Included With Electric Brake Assembly for 6K Axles # 23-459
    I walked out to the warehouse to look at the Electric Brake Assembly for 6K Axles, part # 23-459. The brake assembly does not include the backing plate bolts. I would recommend installing new bolts and nuts for easier installation and safety. For mounting bolt, you would need Brake Mounting Bolt, part # 7-5, which is sold as a quantity of 1. For mounting nuts, you would need Nut for Brake Mounting Bolt, part # 38N, which is also sold in quantity of 1. You will also want to use Lockwasher...

  • Electric Trailer Brakes Work in Reverse But Not Going Forward
    You may have switched the left and right sides by accident when you installed the new brakes. this would not change how the magnets power up but for trailer brake assemblies there is a left and a right and switch them can negatively affect braking. The magnet actuator arm should point towards the front of the trailer. So for # 23-459 as an example based on placement of the brake assembly that has the magnet arm pointed forward you can tell this is a right hand assembly. If you do...

  • Where to Start for Adding Electric Brakes to a Trailer
    If you check out the link I attached you will see a guide that covers everything needed to add electric brakes to a trailer. It's a fairly straightforward process, but before I can recommend you any parts you will need to know what spindles you have on your trailer so that we can pick out the correct replacement hub/drums. Basically everything builds off of what hubs will fit your spindles so I cannot recommend anything until we know what you would need for hubs.

  • Would the Dexter Brake Assembly part # 23-459 fit a Henschen Dura Torque Axel
    If the bolt pattern on your current hub matches the dimensions of the picture I attached the brake assembly part # 23-459 would work well as an assembly to fit it. The matching assembly for the other side of the trailer is part # 23-458.

  • Difficulty Adjusting Nev-R-Adjust Trailer Brakes
    The adjustment wheel that you are using to tighten the brakes just needs to be turned the other way. The adjustment wheel just pushes out the spread of the shoes or takes them back in if turned the other way. Nev-R-Adjust brakes like # 23-459 work the same way as regular brakes except they have a cable in them that works to push the shoes out automatically. Otherwise they can be adjusted just the same as regular brakes. However, on a Nev-R-Adjust accessing the teeth on the adjustment...

  • Bolt Torque Specification for Mounting a 12 Inch Brake Assembly
    According to Dexter Axle, the attachment bolts for a 12 x 2 brake assembly should be torqued to 25-50 foot/lbs. If you don't have a torque wrench handy, if you tighten the bolts until the lock washers flatten out, you'll be pretty darn close to that range.

These self-adjusting brakes have a weight capacity of 2,000 pounds and fit 12 inch x 2 inch drums. For a replacement drum, you will want to use # 8-201-5UC3 if you have standard spindles and # 8-201-5UC3-EZ if you have EZ Lube spindles. The grease seal that comes with these hubs has a smaller inner diameter...

  • Dexter Nev-R-Adjust 6K and 7K Electric Brake Assembly
    The Nev-R-Adjust Electric Brake Assembly for 6K pound axles # 23-459, # 23-458 and the brake assembly for the 7K pound axles # 23-464, # 23-465 are interchangeable in that both are mounted on a 5-bolt pattern and would fit on 12 inch hub/drums. However, the 7K brake has a stronger magnet and upgraded brake shoes with greater stopping power than the 6K. Even though they would fit, you would not want to put the 6K Nev-R-Adjust # 23-459, # 23-458 on a trailer with a 7K pound axle....

    The Dexter and Tekonsha electric trailer brakes we offer are both usable on the same trailers provided that they are the correct drum size, have the correct mounting bolt pattern and are rated appropriately for the trailer's axles.

  • Should Electric Brakes Be Used on a Boat Trailer
    Electric brakes are typically NOT used on boat trailers because water and electricity don't work well together. But what you could do is use an electric over hydraulic braking system. With this set up the tow vehicle will use the electric brake controller (but the Primus is not compatible) to control an actuator on the trailer that, in turn, will control hydraulic drum or disc brakes (depending on how the trailer is set up).

    For a set of 12 x 2-inch electric drum brakes rated for a 6K axle that include the parking brake feature you can use parts # 23-113 (right) and # 23-112 (left) from Dexter. These feature a 5-bolt brake flange mounting pattern. Adjustment of these brakes is made easier by using an adjustment spoon # W80630. We do not offer a kit to allow the parking brake feature to be added to an existing brake assembly.

  • 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.
