As usual with etrailer I ordered a much cheaper brake kit but that one was out of stock and back ordered. It’s frustrating cuz this seems to happen a lot with etrailer. The Dexter brake kits were top quality, bolted on easily and work great. They are made in USA which all of us should be more concerned with. The first product I selected was a chinese made product but the price was right. I am very pleased with the product it’s self, however coming out of pocket with almost $200 more for the the Dexter brakes was an unexpected cost. etrailer needs to stop selling products they do not have in stock!!

Outstanding is the word that comes to mind regarding my experience with the brake kits that I received from etrailer!
I purchased a used Airstream and the brakes were toast.
I called etrailer and spoke to Joseph and he set me up with the kits I needed.
They arrived in 3 days with free shipping and I had all 4 installed in about 2.5 hours on a Saturday morning.
I would definitely do business with these guys again. It was painless!!!

Great!

I recently completed a brake upgrade on my trailer. The new Never Adjust Dexter Brakes went on flawlessly. I found the process to be straight forward. The self-adjusting feature was an upgrade from the previous brakes but bolted on with no issues. I like the idea of not needing to adjust brakes as the pads wear down. I needed all new brakes, this seemed like the best decision for replacements.




by:

The brake kit is excellent. Very easy to install, and in my opinion, they are very good quality. The trailer has about 22,000kms since installation, and the brakes are still in great condition. Have used these before and would recommend these to anyone.




by:

Had problems with regular braking systems applying enough breaking power, No matter how well you kept the brakes adjusted on the trailer the problem was still there I drive a 2021 Ford F-350 a 2015 f350 and a 2012 all with the same problem! Switched to the never adjust breaks and now they work great , this is on a 1990 Logan coach trailer I also have a 2010 platinum trailer with the same problem and will switch to the never adjust brake system on it also
This seems to be a Ford problem but Ford hasn’t been able to come up with a fix, no matter how high you set the brake settings you end up with the same problem very little braking power, was quite surprised and pleased to have the problem solved with the never adjust braking system, don’t know why they work and quite frankly don’t care




by:

If a new RV isn't going to have disk brakes, then they should all come with these. Pretty straight forward replacement. I didn't get new drums, just had the old ones turned.




by:

A reviewer on your site mentioned his grease seals leaking. Well that's just what seems to have been the problem on our trailer. Although the brake shoes and magnets were worn the real problem was the grease, I think from the previous owner pumping too much grease in after each use. I've replaced the brake units and inner seal on one axle(the front) and it should make quite a difference. Glad I went with original Dexter parts.




by:

Super easy to install, very fast shipping and packaged well. I replaced all the brakes on my horse trailer, due to worn out wiring on the magnets, which was causing brake failure.




by:

Easy Peasy to install. Just need a chisel, snap ring pliers, and 36mm socket to get the drums off. (Never-Lube bearings) Then a 9/16" socket and some wire cutters to get off the backing plate. Be sure to get heatshrinking crimp-on connectors to reattach the wires behind the backing plate. Everything went together smoothly. Still need to tow the trailer and let the self adjusters do their thing, but it'll be awhile before our next trip.
FWIW we have an Airstream with about 50K miles on it and I replaced the brakes as a precaution. They actually still had many miles remaining on the linings and magnet.




by:

It’s been a year and almost 5K miles on the new brakes. Absolutely no problems whatsoever. Will definitely purchase again when the time comes.


Comments
I replaced them about 4 months ago with the Lippert brakes. I wasn’t happy with the performance I was getting out of the Dexter Brskes.
Bill S - 09/28/2021


by:

To be honest they ate still in the nox sitting in my shop. We are too busy to place the trailer putbof service and do the work. So as of Now they are looking great in the box.




by:

Everything was packaged well, and received the brake assemblies in a very timely manner. Great service.




by:

After one year, brakes are still working


Comments
Working perfectly!
Nick - 02/12/2022


by:

Etrailer service was great, install was very easy, and so far they are staying in adjustment. Very happy with this product.




by:

i have only used the new brakes for 1000 miles or so, but they have worked as expected. delivery was prompt. i would definitely buy from etrailer again.

when installed, i was chasing a brake issue which my in the cab brake controller identified as an intermittant short circuit. i could have diagnosed the cause to a specific wheel, but decided to replace all four wheel brake assemblies since the existing units were original, about 12 yrs old, but in good condition. doing so did not fix the problem, but eliminated the brake assemblies as a possible cause. the cause of the fault was in one of the two cross axle wire cables. i replaced all of the trailer brake wiring starting ahead of the forward axle, and that solved the issue although i was not able to find the exact location of the short. while replacing the cable, i re-routed the wiring so that none went through an axle tube and the length of the cable to each wheel brake was equal to the others. keeping the runs equal in lenght insured equal power to each wheel with the hope that all four wheels would brake evenly.


Comments
after about another 1000 miles and one year, im pleased to report the new brake assemblies from etrailer as well as the rewire of the trailers brake system are performing well.
Tg - 01/30/2020



by:

Very nice brake set up. Delivered as stated. Installation was a snap.
Pre lubed hubs are the way to go. Just slide them on and set the tension.
One dust cap was dented in shipping or packaging? But did not defray from the product quality.




by:

Everything came and went on fine. check to make sure the shoes and adjusters are seated properly before installation. Mine weren't. One inner grease seal was damaged and I had to buy another one at the local parts store to complete my installation (hence the 1 star reduction). Note that the outer washer is not included with the hub/drum kit and you will have to reuse your old ones.


Comments
Thank you for your review. I apologize about the grease seal. Customer Service will be contacting you to remedy it.
-- Etrailer Expert Sierra K - 08/03/2021


by:

It took me a while to get them right, but now they're working well. You have to put the hub on and off, adjusting the shoes, until the shoes are out as far as possible, centering the shoes, by operating the brakes between trys. After that they will adjust themselves, but if they are not adjusted close, they won't.
The installation and wiring is child's play, just make sure the shoes barely scrape the drums. After that they've stayed adjusted up well. I took a 3000mi. trip and they performed well.


Comments
Definitely 5 stars. They took a little tinkering to get adjusted to the point where they would adjust themselves, but that 2 years ago, and Im very happy. My 37ft.5th wheel stops so much better. Id do this again in a heartbeat.
Jim S - 12/01/2020


by:

Pre-assembled with all the parts needed, installed very easily. My only improvement would be for longer wires for connecting the brakes.




by:

The whole experience of ordering my replacement brake assemblies was awesome. Teresa did a fantastic job of figuring out which parts I needed. I would not hesitate to order parts from e-trailer in the future. The quality and fit-up of the Dexter brake assemblies made repairing my rv easier than I could have imagined. I am one happy camper. Thank you for an awesome consumer experience from start to finish.


Comments
The parts I purchased are working fantastic. I still consider the complete experience to be a 5-star transaction and will definitely order from e-trailer if I need parts in the future.
Kent C - 04/25/2020

One year later: replacement brakes were an exact fit and have performed flawlessly on the trips which took us from SC to Florida Keys, then to western NY and back to SC. Thanks etrailer.com.

    The correct electric trailer brake kit for a 2013 Jayco Jay Flight 28BHBE is the Dexter Nev-R-Adjust Electric Trailer Brake Kit part # 23-458-459. That said, I understand this may be confusing because the axle tag says you have a 4,400 lb axle and the above brakes are for a 6,000 lb axle but this particular axle actually uses the larger brakes so no need to get hung up on this.

  • Troubleshooting the Adjustment or Lack of Adjustment on Self-Adjusting Brakes
    To get your brake assemblies to start self-adjusting after the initial manual adjustment at install, you will need to hit the brakes hard multiple times. I recommend having the truck and trailer on a fairly smooth and level surface in a parking lot for this adjustment. You will slowly accelerate to no more than 20 mph, then hit the manual override on your brake controller to its max. It will be jarring, so be prepared. You will need to do this a few times. Then you can do the same...

    Yes, since the brake kit is rated up to 6000 per axle and has a 12 x 2 Inch drum you should have no issues applying Dexter Nev-R-Adjust Electric Trailer Brake Kit # 23-458-459. This kit fits wheel sizes 14-1/2", 15", and 16". The (extra) steel cable you see is part of the linkage mechanism which makes the assemblies adjust automatically.

    You can initially adjust your Dexter Nev-R-Adjust Electric Trailer Brakes # 23-458-459 but the adjustment tool you are using might just be too thick to get to the adjustment wheel. You should use something that allows you to more easily access that wheel (as shown in picture) such as a flathead screwdriver.

    It sounds like you are asking what wire should be ground and which is power for installation of the Dexter Nev-R-Adjust Electric Trailer Brake Kit # 23-458-459. The wires can be used for either, so if you want to use the black for ground you can, and the white wires will then be the power wires.

  • Troubleshooting Trailer Brakes on One Side that Apply Harder than the Other
    The issue seems to be different adjustment than the other side. Most likely the time delayed onset of the braking pressure is locking up the one side of the trailer before the other due to it being a tighter adjustment. What you can do is tow the trailer around at a slower speed and apply the trailer brakes with your override lever several times and witch each application they will tighten by one click until they are equally tightened between both sides.

You do need to connect each of the wires to your brake assemblies, and each should have its own ground.
