Pam was great to work with. Ordered on Friday night they arrived on Tuesday. This may not be the cheapest way to do a break job, but it is the easiest. I went to the dexter dealer near home, they could order them, but it would be at least 4 weeks to get them, if they were in stock at the warehouse.

I was in trouble time wise to get my trail brakes fixed. I called Montrell at etrailer...He was extremely helpful to quickly process my order. The brakes came before the time quoted, and they were put on and done quickly. I will always start with etrailer when I need products that you have. Thanks to your company and Montrell.

My order was taken courtesly, delivered on time and received as ordered! The Dexter brake assembly was the correct match and installed with minimal effort. I haven't pulled the 5th wheel yet so can't comment on practical use but dealing with etrailer has been seamless. Thanks.

I ordered 2 sets of 10" 2 1/4 electric shoes / self adjusting for my Jayco eagle. Received them about 5 days after i ordered them. have installed all but 1 on rear axle. They were very easy to install and wire. tested them today while burnishing them going to another park so far they work well. hope to finish the last on soon. I did replace all bearings and seals on each wheel as i was changing them out.

Review from a similar Nev-R-Adjust in Trailer Brakes


Thanks to everyone that helped get the correct breaks for my 1905 Roockwood Mimi light. They are installed now. Just need to be broke in.

I have had new brakes on my rockwood mini light for a year now. I have about 10,000 miles on them and they are still working like new. I could not be happier with them.

Review from a similar Nev-R-Adjust in Trailer Brakes


Everything fit just right wired up just fine takes a little while to break these things in but once they start biting they work really nice I did a little bit more than just replace the brakes I did the shocks, springs and equalizer then re-painted everything underneath too,pretty much rebuilt the entire suspension sure makes a difference. I'm including some before and after pictures here they're probably out of order but them's the berries folks !

Excellent product. Had minor grinding to perform to weld on axle Plates. Would recommend to everyone installing brakes on a trailer. Was very surprised to have the quick turn around time from ordering and receiving. Will definitely use etrailer in the future. Thanks

Ask the Experts about this Dexter Axle Trailer Brakes



  • Choosing the Correct 10 x 2-1/4 Inch Electric Brakes
    The brakes need to fit the axle. Or more specifically the hubs and the brake mounting flanges on the axle. One thing that may be confusing you is that brake assemblies for 4,400 pound axles and those for 3,500 pound axles are both 10 x 2-1/4 inches. The difference will be the brake mounting flange bolt hole pattern. If your axle is a indeed a 3,500 pound axle # AKEBRK-35-SA will work for you. The mounting bolts are included but you need part # BRKH10B for the nuts and lock washers. If...

  • Adjustable Electric Trailer Brakes for 4,400 lb Axle
    Thank you for the photo, which has your axle's capacity at 4,400 lbs; what that means is the correct self-adjusting trailer brakes are the Dexter Nev-R-Adjust Electric Trailer Brake Kit - 10" - Left and Right Hand Assemblies - 4,400 lbs # K23-478-479. If instead you were referring to brakes which are manually adjustable then you would need the Dexter Electric Trailer Brake Kit - 10" - Left and Right Hand Assemblies - 4,400 lbs # K23-462-463-00; you would also need the Brake Adjustment...

These are the standard manual adjusting brakes but we also have the Nev-R-Adjust (self-adjusting) brakes as well as part # K23-478-479 if you'd like to go that route. The hub/drum assembly isn't included with this kit but it is available as part # 8-407-5UC3-EZ. This has a 6 on 5-1/2" bolt pattern...

  • Difference Between Dexter 3500 lb and 4400 lb Brake Assemblies
    Actually, there's a little more to it than that. The magnets on the # K23-478-479 are a little different, but the primary difference is the mounting bolt pattern. On a typical 3500 lb brake assembly, the mounting studs will all be 2-7/8 inches apart on center. On the # K23-478-479 4400 lb brake assembly, the top studs are 2-7/8 inches apart, but the bottom ones are spaced a bit further apart to prevent a 3500K brake assembly from being used on a 4400K axle.

  • Replacement Brake Assemblies and Grease Seals for Dexter 4400 lb Trailer Axle
    I'm assuming the hubs are used on a 5th wheel, is that correct? For a tandem axle setup, the combined axle capacity would be 8800 lbs. The remainder is carried by the rear axle of the tow vehicle, since the pin weight of a 5th wheel is typically 20% of the GVWR, the axles are properly rated for your RV. For replacement brake assemblies, I'd recommend the # K23-478-479 from Dexter, which includes right and left auto adjusting brake assemblies. After the initial setup, the brakes will constantly...

    There is no difference between buying the brake assemblies individually or as a kit with the Dexter Nev-R-Adjust Electric Trailer Brake Kit - Left and Right Hand Assemblies # K23-478-479.

  • Replacing Electric Brakes and Grease Seals on Dexter 4400-lb Axle
    Trailer axles with EZ-Lube spindles like # TRU74FR or Bearing Buddy grease caps like # BB1980A-SS do certainly make it a lot easier ensure your hubs are adequately greased, but like many before you (and many that will inevitably follow) you have found out that this feature also makes it easy to accidentally over-fill your hubs with too much grease which can result in blown out grease seals and also contaminated brakes. We can help you with both new seals for your hubs and new electric brakes...

  • Which Replacement Hub/Drums for 4.4K Dexter Torsion Axle
    The 4.4K axle uses a fairly unique bearing set, so you'll want to check the reference numbers on your inner and outer wheel bearings to ensure the replacement hub uses the same wheel bearings. If your current hubs use a LM67048 inner and a L44649 outer bearing (which they should), then the correct replacement hub drum is part # 8-407-5UC3-EZ. The hubs have a 6 lug on 5-1/2 inch bolt pattern and are sold individually. The hub includes the inner and outer bearing, the races which are pre-installed,...

    Thank you for the photos, though there is only one measurement there so it would be very difficult for me to tell you exactly what you currently have.

    For your Lippert 4,400 pound axle I definitely recommend going with 4,400 pound electric brake assemblies. Lower rated assemblies will have a weaker magnet that won't provide sufficient stopping for a heavier trailer like yours. For this the Dexter Electric Brake Kit # K23-462-463-00 or the Nev-R-Adjust # K23-478-479 for easier maintenance will work perfectly.

  • Replacement Trailer Brakes for Tandem 3,700 lb Axle Trailer
    Trailer brakes can definitely wear faster depending on the style of driving and the terrain, but that sounds like excessive wear. You should get way more than 3,000 miles out of a set of brakes. With your axles you must be using the 4,400 lb assemblies instead of the 3,500 lb assemblies. For the replacements I recommend the Dexter Nev-R-Adjust Electric Trailer Brake Kit - 10" - Left and Right Hand Assemblies - 4.4K # K23-478-479 or the manual assemblies # K23-462-463-00.

  • Does Surge Coupler Need to Be Replace if Trailer is Converted to Electric Brakes
    It isn't necessary to remove the existing hydraulic coupler, but you'll want to come up with a method to prevent the coupler from articulating. Many hydraulic couplers have a hole on either side that allows you to install a cross-bolt to prevent the movement, or you could tack weld the lockout so it stays on all the time and prevents movement. If this isn't an option, you could certainly replace the coupler using a 2 inch coupler for a 3 inch channel frame member like Demco eZ Latch, part...
