  • Adjuster plugs (included) protect internal components from dirt, grime, and road debris
  • Durable magnets ensure consistent braking power

Quick Tip: There's really not a whole lot to getting new drum brakes. If you've confirmed that all of the specs listed above line up with what you need for your trailer, you can be pretty sure these will work for you.


Self-Adjusting Brakes Don't Require Routine Maintenance

With standard electric brake assemblies, you need to manually adjust them every now and then to make sure you're getting the shortest stopping distance every time you tow.


A trailer drum brake with a red callout shows the location of a tension cable and pulley on a self-adjusting trailer brake.

With self-adjusting brakes, though, you'll always have peak stopping power - simple as that! As the brake pads wear over time, a tensioning cable will automatically keep the pads in alignment so they'll consistently make contact with your drum when you brake. You won't have to do tedious manual adjustments anymore.


Thoroughly Tested for Safety

Dexter invests a lot of resources to ensure that these brakes meet the requirements for certification set by the Canadian Standards Association (CSA). Basically, a CSA certification tells you that these trailer brakes are well built and safe for use on the road.


How to Break In New Brakes

Once you get these brakes installed, you'll need to break them in. First, find a long stretch of road or a big, empty parking lot. Once you're there, set your brake controller to its maximum setting and get moving. Speed up to about 40 mph and brake to slow to about 20 mph. Repeat this 15-30 times. The goal is to get the brake shoes and magnet properly seated into your drum. You'll know you've done that when it feels less jerky (and more consistent) each time you apply the brakes.


Note: The brakes will be very hot after doing this, so after every 10 stops you'll want to wait about 10 minutes to let the brakes cool off before continuing. If you don't, you might cook and crack the pad material.

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!

Just like to say that those self-adjusting brakes that I bought a year ago working fine way better that my old breaks that I had to adjust myself you got yourself a satisfied customer etrailer



by:

Excellent service and etrailer was very helpful on which brakes I needed.



by:

My Brake order was delivered on time .Brake assemblies were in seperate boxes (4) which were in a oversised box allowing them to bang around and dislodge the shoes on one assemblies.Trip to Orilleys auto parts for tools to take assembly apart and reline shoes again .Couple of Hrs. wasted.



by:

perfect replacement on my 3 axle toy hauler camper. Fast shipping and good commication.



by:

The Dexter brake kit was easy to install and are working great. I recommend that you also replace the brake drums as well. I didn't replace mine and the magnets are already getting grooves in them from the worn drums. Next time, I will replace the brakes and drums at the same time.



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:

I ordered 4 brake assembles for my Fifth wheel trailer to be delivered to an RV park we were staying in. They arrived on the day they said they would when I put in the order. Well packaged. Replaced my worn out brakes perfectly. I have ordered from etrailer a few times now and have yet to disappointed with delivery or product.



by:

Fast shipping - parts installed with zero issues.

Brkes survived winter storage without locking up and still work perfectly!



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.

Still working fine. Have put many miles on the new brakes - like participating in a caravan that went around the island of Newfoundland for two months...



by:

Once I received undamaged assemblies the install was straight forward. I was happy with customer service in exchanging parts. Brakes seem to work fine…(have not had to panic stop yet) Only complaint was the burnishing process. (Burnishing procedure is required for all brands of trailer brakes)



by:

Exact replacement for original brakes and way less expensive than rebuilding the brakes part by part. I like the made in America labels too!



by:

William was a great help with his advice on replacing my trailer brakes and hubs and what parts and equipment I needed. I purchased with total confidence. To my amazement the parts arrived in two days! Outstanding service from a company I've come to know and trust over many years.



by:

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:

Every thing went well. Excellent servic e!



by:

Everything fit and works as it should.



by:

Easy to Install. Working great.



by:

Brakes were perfect fit and still working great.
Would highly recommend.



by:

Great customer service! Excellent help finding the correct parts. I had some unusual issues that where resolved quickly. Was even provided a direct phone number. Don't get that kind of service much these days!



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.

I ordered 4 brake assemblies 4 mo ago and just got around installing them. Found one assembly bad and contacted etrailer expecting them not to replace due to the time frame. Thanks to Kate F., she made things right and sent a replecement.



by:

Thank You etrailer and in particular Adam E. I realized that the brakes on my 2005 Airstream Safari were not going to adjust enough to provide safe braking for our planned trip from Indianapolis, IN to Santa Fe, NM, Cortez, CO, and Moab, UT I called etrailer on Thursday Sept 26 and spoke with Adam E. I explained my trailer setup -
12 x 2" brakes on a 4400# Henschin double axel The brakes I was looking at were listed for Dexter and Lippert axels - there was no mention of the Henschin axels I was working with. I asked Adam E. if he had the bolt spacing for the 5 bold mounting flanges - he researched a diagram in etrailer archives which showed the bolt pattern and spacing - I matched the pattern and ordered for overnight shipment - Adam E. made shure my order was shipped - they arrived as requested on Sept. 27 I installed the Dexter brakes successfully on Sept. 28 and we left Sept. 29 on a wonderful 4100 mile trip through the great SouthWest with comfort and confidence knowing we had plenty of stopping power for any terrain we might find. Thank You Adam E. and etrailer Great People / Great Service / Great Products / Great Prices

  • 12 x 2 Self-Adjusting Electric Brakes For 6,000 lb or 7,000 lb Dexter Axle
    For a 12" x 2" hub and drum, there are a couple of options for self-adjusting electric brakes, depending on if your Dexter axle is rated for 6,000 lbs or 7,000 lbs: - 6,000 lbs: Dexter Nev-R-Adjust Electric Trailer Brake Kit # 23-458-459 - 7,000 lbs: Dexter Nev-R-Adjust Electric Trailer Brake Kit # 23-464-465 For the installation you will also need the Mounting Bolts and Hardware for 12" Brake Assemblies # BRKH12.

  • How To Make a 2020 Airstream Globetrotter Be Able To Go Off-Road
    The best option we have for you to make a 2020 Airstream Globetrotter more off-road savy is with the Timbren Heavy-Duty Axle-Less Trailer Suspension like part # ASR35HDS02 which has an integrated 4" lift, 3,500 lb weight capacity, and larger spindle to accommodate off-road tires. The independent design when combined with the axle-less clearance will be ideal for off-road driving and the incorporated lift will again provide better clearance as well as allowing for larger tires to be used....

This brake kit is self adjusting so that you will not have to adjust the brakes after the first 200 miles or every 3,000 miles after that. It has the same 5 bolt mounting pattern and includes a brake for the left and right side. The Dexter Trailer Hub and Drum Assembly # 8-201-9UC3-EZ contains 1 complete hub assembly with the correct...

  • Replacement Brake Assemblies for Dexter 5,500 lb Torflex Axle
    Since you have self adjusting brakes on your Torflex 5,500 lb axle the correct replacement would be the part # 23-458-459. It's almost always best to replace entire assemblies and not just the pads as the pads end up costing quite a bit, are much harder to install, and you don't end up with new magnets at same time which do wear out as well.

  • Does it Matter Which Wires are Power or Ground for Electric Trailer Brakes
    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. You should then connect the ground wire to the trailer frame and connect the others to power like in the cut out I added. This is from the linked help article "Parts Needed to Add Electric Drum...

  • Can 7k Trailer Brake Assemblies be Used in 6k Trailer Axle Hub/Drums
    Yes, 7k trailer axle brake assemblies like # 23-180-181 will fit 6k axle hub/drums. They use the exact same dimensions and bolt patterns which allows that. The difference is the strength or sensitivity of the magnets in the assemblies. The 7k axles have a magnet that is more sensitive and will pull harder on the drums. This might seem like it would give you more stopping power but in reality a 6k assembly set would just as easily lock up the brakes so there is no more stopping power gained....

  • Availability Of Hub/Drum Kit With Brakes And Hardware Similar To Part BPH1206EPR
    Hello Brian, we do offer some parts that will work for your application and will be very similar to the BPH1206EPR kit that you mentioned. Like you said, the 12 x 2-1/2 drums are pretty uncommon, so I would have to recommend going instead with the standard 12 x 2 drums which will be readily available. Take a look at the parts below. Aside from the drum depth specs will be identical. Dexter Trailer Hub and Drum Assembly - 5,200-lb and 6,000-lb Axles - 6 on 5-1/2 - Pre Greased # 8-201-9UC3-EZ Dexter...

  • Replacement Brake Assembly Recommendation for 2004 Fleetwood Prowler Regal 32'
    Best option is to match the part number you found on your trailer. Realistically the 6k and 7k brake assemblies are mostly interchangeable as they both are 12 inch diameter by 2 inch width so either would technically fit, but going with the correct rating gives you a setup that's easiest to fine tune braking power. If you go with an assembly rated too high the magnet is more sensitive and you'll find that the brakes are harder to get the exact amount of braking power. It'll either feel...

    The Dexter Trailer Hub and Drum Assembly # 8-174-5UC3 is for 6,000 lb and 7,000 lb axles and has a 12" diameter x 2" wide drum. The best brake assemblies that fit a 12" x 2" drum are the Dexter Nev-R-Adjust Electric Trailer Brake Assemblies. For a 6,000 lb axle you need the Dexter Nev-R-Adjust Electric Trailer Brake Kit # 23-458-459 and for a 7,000 lb axle you need part # 23-464-465.

  • Is There a Kit That Can Convert Dexter Manual Adjusting Brakes Over to Nev-R-Adjust Brakes?
    I spoke to Dexter and the # DX43QR will be the replacement kit for 12" Electric Nev-R-Adjust brakes. Unfortunately, they said adding this on to your manual adjusting brakes will not make them work the same as the Nev-R-Adjust ones. If you want to get the Nev-R-Adjust brakes on your trailer, you will need to go with the # 23-464-465 for a 7,000 pound axle, or the # 23-458-459 for a 6,000 pound axle. Both of these options will fit your 8-219 hub/drum without issue.

  • Replacement Brakes for 1983 Airstream Excella
    Based on an old brochure from Airstream it looks like you have 12" electric drum brakes like the Dexter Nev-R-Adjust # 23-458-459. These are 12" diameter x 2" wide brake assemblies with a 5 bolt brake flange pattern. I recommend double checking what you currently have to verify this information. As for shocks, everything indicates you have torsion axles. Unfortunately, we do not carry any shock kits for torsion axles.

  • Are Initial Adjustments Necessary for Dexter Nev-R-Adjust Trailer Brake Assemblies
    Technically speaking, it's not really necessary to pre-adjust Nev-R-Adjust brakes. You'd find a big empty parking lot, set your brake controller gain to 50 percent or so and speed up to 25. Then hit the manual brake switch on your brake controller without using the tow vehicle brakes. These should be hard stops. Once you do this a few time, you'll feel the brakes becoming more and more effective. Once you've done this 6 or 8 times and the braking intensity doesn't seem to change, then you...

  • 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.
