Correct part that was ordered

I’m so glad eTrailer is that good! Its the only seller of this 4,400# brake. Thanks so much



by:

I am happy to say that my Dexter Nev-R-Adjust Electric Trailer Brake Assembly is working great. I especially appreciate how easy the installation was. My originals got really fried and left me with no trailer brakes going over the mountains.



by:

Replaced bearing, seals, drums and breaks. Everything fit after we changed the breaks that I had originally ordered. Again that’s to all that worked with me to exchange brakes for the correct ones. Looking forward to going to Florida for the winter now.

Everything is working great. Just finished re- lubricating the axel bearings and we have went close to 10,000 miles now on the brakes and bearings. I only have 1 axle so I can’t afford a brake down. But you never know what will happen.



by:

Great price and quick delivery. The local RV service center did not carry the Dexter electric brake assembly and could not fix my trailer brake quickly enough because they were booked for a month. I was able to replace the brake myself with the unit I got from etrailer. It was easy to install since it comes preassembled and ready to mount. There are a number of online videos available showing how to connect the wires and the proper way to mount the brakes.



by:

Genuine Dexter parts at very reasonable prices with free shipping at certain $$$ levels. Excellent part discriptions with accurate & precise pictures. Quick shipping, excellent refund policy just be sure to keep original packaging until sure about part being correct. etrailer is my 1st choice for parts for my trailers or towing accessories.



by:

The dexter Nev -r-adjust electric trailer brake assembly had to be replaced after 3ooo miles ..a piece of junk.



by:

Received product today and it was packed in a very protective, sturdy container. There was excellent communication with Etrailer during the procurement process. I won't be unpacking the items for a bit but I'm very confident everything will be OK. You know, that gut feeling kind of thing. Thank you Etrailer.



by:

The assembly arrived undamaged and with all the required installation hardware. It was a simple install. The only improvement opportunity is with the enclosed instructions, they did not provide direction on the initial adjustment of the brake shoes, but only referred to Dexter's website for such instruction.



by:

Received said parts on time. ordering and shipping process was easy, straight forward and much appreciated. Have not installed or looked at parts at this time but expecting all to go well.



by:

I have never had any complaints about the parts or assistance received from E-trailer. I'll be back for more "stuff" as needed. Thanks for filling my needs in such a professional manner. I hope this will get everyone a well deserved raise.



by:

I’m very happy with the service from etrailer

  • Never Adjust Dexter Brake Assemblies to Replace Dexter 023-454-00 and 023-455-00 Assemblies
    The Dexter Nev-R-Adjust Electric Trailer Brake Assembly equivalent to your current assemblies is part # K23-478-00 for the left and part # K23-479-00 for the right side. Please check the mounting pattern of your current assemblies to the # K23-478-00 for the left and part # K23-479-00 for the right side because these have a very specific mounting flange pattern. I am not able to add the photo right now but if you go to the product pages of K23-478-00 and K23-479-00 you can see the diagram.

  • Recommended Trailer Brakes for 2006 Bigfoot 21 FT Travel Trailer
    From the research that I have done it looks like a 21 ft Bigfoot is going to weigh about 4000 lbs so I am going to assume that it has 4400 lb axles. Since there is a very good chance that it has the 10 inch x 2-1/4 inch brake assemblies, you could use the Dexter Nev-R-Adjust Electric Brake Assemblies, # K23-478-00 for left hand and # K23-479-00 for right hand. Unfortunately a collective OEM trailer parts catalog does not exist, so the best way to determine what parts you will need is...

  • Cushioned Equalizer Fit for 2015 Prime Time Lacrosse 318BHS
    Looks like you have a longer equalizer setup on your 2015 Prime Time Lacrosse 318BHS but I would need the length of the equalizer to ensure we get you the correct replacement. We do have the Equa-Flex Cushioned Equalizers # LC314336 which appears to be what you are in need of. It measures 14-5/8 inches from the side holes and then 3-1/4 inches vertically so you'd need to measure yours to compare. This is a cushioned equalizer setup that will smooth out the ride quality of the trailer.

  • Brake Assembly Replacement Recommendation for Dexter Assemblies 36-19-47
    Based on what you described you have a standard 4-bolt trailer brake assembly bolt pattern. For brake assemblies that match that and the 4,400 lb axle capacity you have you'd want the part # K23-478-00 for the left hand side and part # K23-479-00 for the right hand side. For a brake flange you'd then want the part # 4-35 if you were also in need of that.

  • Can Electric Trailer Brakes for a 4,400 Pound Axle be Used in Place of Brakes for a 3,500 Pound Axle
    Electric trailer brake assemblies for both 3,500 pound and 4,400 pound axles are 10 x 2-1/4 inches and both have the 4 hole square mounting pattern. So you can use 4,400 pound axles brakes. For the left use # K23-478-00 and for the right use # K23-479-00. These are Nev-R-Adjust assemblies which means after you adjust them the first time you will not have to manually adjust them again.

  • Brake Assembly Recommendation for a Dexter 4,400 lb Axle with 10 inch Assemblies
    By the time you add up the cost to replace the magnets and shoes on your trailer you are at the cost (or more) for all new assemblies plus you end up saving yourself the trouble of messing with trying to install all the components. For an exact replacement for the assemblies of your trailer you would want the part # K23-478-00 for the left hand side and part # K23-479-00 for the right hand side. Replacement parts for these assemblies are even harder to find than normal assemblies due...

  • Replacement Brakes, Bearings & Seals for AL-KO 4400-lb Axles on 5-Year-Old Tandem Axle RV
    The # K23-478-00 and # K23-479-00 Dexter brake assemblies you mentioned are not compatible with your AL-KO T-44 axle. According to my contact at Dexter (AL-KO was acquired by them), the replacement brake assemblies for your AL-KO axle are now obsolete as they have been discontinued. The only option is to replace the axles on your RV. Since we don't carry any 4,400 lb axles, the closest rated axle we have (that would also match the 6 on 5-1/2 wheel bolt pattern found on the T-44 hubs)...

  • Electric Brake Assembly Compatibility with T-44 4,400 lb AL-KO Axles
    The AL-KO company was bought out by Dexter, so he may have been thinking Dexter axles which the # K23-478-00 and # K23-479-00 would fit with the 4 bolt mounting pattern. The K23-538-00 and K23-539-00 are the correct ones for the AL-KO T-44 axle, as you mentioned but they have been discontinued. The only option is to replace the axle(s). Depending on the hub face and spring center dimensions of your existing axle and wheel bolt pattern, we may have what you need. I have included a link...

  • Replacement Brake Assemblies for AL KO 4,400 Trailer Axle
    For 4,400 AL KO trailer axles the correct replacement brake assemblies are part # K23-478-00 for the left hand side and part # K23-479-00 for the right hand side. It is much easier to just replace the assemblies instead of trying to individually replace all of the components. It often ends up costing about the same as well.

  • Nev-R-Adjust Brake Assemblies for a 4400 lb Dexter Axle
    There are a few differences between the Dexter 3,500 lb brake assemblies and the 4,400 lb brake assemblies including the brake shoes, magnets, adjusters and adjuster springs. Because the 4,400 lb brake assemblies must be able to provide more stopping power than the 3,500 lb brake assemblies they will have upgraded components. The 4,400 lb brake assemblies also have a different bolt hole pattern on the backing plate to mount to the brake mounting flange on the axle than the 3,500 lb brake...

  • Is There a Difference Between Brake Assembly Kit and Individual Brake Assemblies for 4,400 lb Axle
    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. Prices have to do with things like demand, and some people only need individual assemblies, so the prices can be different because technically they are different part numbers. But to get to the heart of your question, you can absolutely order the brakes individually and there is no difference. - Dexter...

  • What is the Difference Between All the 10 x 2-1/4 Inch Brakes
    When it comes to 10 x 2-1/4 inch brake assemblies there are a few things you need to consider before purchasing. The first you will need to know is if you have electric or hydraulic brakes on your trailer. There is also a difference in the weight capacity of the axles the will fit. There are 3,500 lbs and 4,400 lbs axles ratings. However, the 3,500 lbs and electric brakes are the most common size. After these two factors are determined, then the rest is a personal preferences.The etrailer/Axle...

  • Can Self-Adjusting Brake Shoes Be Used On Manual-Adjusting Dexter Brake Assembly?
    I do not recommend using the self adjusting brake pads for your manual adjust brake assembly as they are not designed to be used together. If you want the self adjusting setup then you will want to go with Dexter Nev-R-Adjust Electric Trailer Brake Assembly - 10" - Left Hand - 4,400 lbs # K23-478-00 and Dexter Nev-R-Adjust Electric Trailer Brake Assembly - 10" - Right Hand - 4,400 lbs # K23-479-00.

  • Torque Specs of Mounting Flange Bolts on Dexter Nev-R-Adjust Electric Trailer Brakes
    I spoke with a representative of Dexter who told me that the 4 mounting flange bolts on the Dexter Nev-R-Adjust Electric Trailer Brake Assembly # K23-478-00 (left hand) and # K23-479-00 (right hand) who was unable to confirm the specific torque specs of these assemblies. However, based on similar assemblies from Dexter we do know that in the past the recommended torque is between 45-70 foot lbs.

  • What Parts Are Needed to Replace Hub/Drums and Brake Assemblies 4,400 lb Trailer Axle
    Hey Rob, sorry to hear about the problems you had with your current hub/drums. The good news is you did order everything you would need and no additional parts would be necessary. The two pieces you pointed out with your yellow arrows do need to come off as they are parts of the old bearings that were destroyed.

  • Replacement Dexter 10 Inch Electric Brake Assemblies for Off-Road Camper
    To replace the 10 inch brake assemblies on your offroad camper I recommend the Dexter Electric Trailer Brake Kit # K23-086-087-00. This kit includes both the Left Hand and Right Hand assemblies and will work perfectly as replacements to your existing Dexter units that include the manual parking brake levers. I do agree that going with a complete replacement will be easier and likely more cost-efficient than trying to replace individual components. I have attached a short video demonstration...

  • Brake Assembly Recommendation for a 2004 Keystone Cougar 285 Camper Trailer
    I did some research on your 2004 Keystone Cougar and it looks like it's a tandem axle trailer with a dry weight of 7,340 lbs. Keystone almost always uses Dexter axles so the correct brake assemblies should be 4,400 lb rated 10 x 2-1/4 inch brake assemblies like the part # K23-478-00 for the left hand side and part # K23-479-00 for the right hand side. Or if you measure the diameter of your assemblies and they are 12 inches you would instead need the part # 23-459 for the right hand side...
