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.

After doing my homework on what I needed for my Grand Design 230 RL finding the original equiptment replacement parts was essential. After much time on the internet E Trailer had what I needed. I was taken back by the pricing after my search showed some less expensive replacements of the not OE quality. Upon receipt of my purchase I see why the price. Very high quality. Happy me.



by:

Easy to install and have been good reliable brakes for several trips so far. Although, extremely expensive. At over 3 times the cost of the next size down, seemed excessive, but if that’s the size you need you have no choice.

Great service. Got everything fast and complete. Great product and service.

It took awhile to get the correct part numbers, but when done, the product installed nicely! Highly recommended.

The parts received were the correct ones. After trying to find them locally and being sold the incorrect parts and then after several days being told they were unavailable, it was a relief to easily find, order and receive the corect parts. Thank you etrailer!



by:

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.

  • How to Determine 3,500 lb Electric Brake Assembly Fitment
    The Electric Trailer Brake Assembly - Self-Adjusting - 10" - Right Hand - 3,500 lbs # AKEBRK-35R-SA and Left Hand # AKEBRK-35L-SA may be a fit for your 2016 Heartland Mallard M32 though you do need to ensure you have the correct weight capacity, drum size and brake mounting flange. However, since you referenced a part number for brakes that fit trailers for axles before 2009, you may be talking about a kit from Dexter for 4,400 lb axles. Since you have a 2016 trailer they would not fit,...

  • Can 2013 Forest River XLR 27HFS Toy Hauler W/ 4400lb Axle Use 3500lb Brake Assemblies?
    We have exactly what you are looking for! Since your 2013 Forest River XLR 27HFS toy hauler has a 4400lb axle instead of a 3500lb axle you would not want to go with 3500lb braking assemblies. The reason for this is the strength of the magnet will be less and you will have less braking power. Even though a 3500lb assembly and 4400lb assembly are the same size and could be interchanged, I recommend going with the Dexter Nev-R-Adjust Electric Trailer Brake Kit - 10" - Left and Right Hand...

  • Best Brake Assembly Setup for Trailer with 4,400 lb Axles
    For a set of brake assemblies that are a fit for the 4,400 lb axles you have on your trailer the part # K23-478-479 would be the best option. You'd need to verify the bolt pattern of the mounting flanges though. See picture. These are Dexter and they are self adjusting which means you'll never have to mess with adjusting assemblies. Also make sure the trailer is using 10 gauge wire for all of the brake controller wiring like our part # 10-1-1 which we offer by the foot.

  • Replacement Brake Assemblies for 4400 lb Axles on 2013 Keystone Outback TT
    From what I've been able to determine, your axle is a AL/KO 4400 lb axle, which would use a 10 x 2-1/4 inch brake assembly. Dexter offers a set of self adjusting brake assemblies, part # K23-478-479 that would be compatible, but I'd like you to measure the bolt hole spacing of your brake mounting flanges, just to be sure. If the top holes are 2-7/8 inches apart and the bottom are 3-1/4 inches apart as shown in the provided photo, then the # K23-478-479 would work for you.

  • What Brake Assemblies for 4400 Lb Axles
    A 12 inch 5200 lb rated brake assembly isn't compatible with the 10 inch hub used by a 4400 lb axle, but we do indeed offer 4400 lb brake assemblies, as part # K23-462-463-00 for standard brakes or for self adjusting brakes (which I'd recommend), use part # K23-478-479. Either set of brake assemblies would be compatible with the brake drums used on your 4400 lb axles. Either set of brake assemblies mentioned above include the adjuster hole covers and mounting hardware.

  • How Do I Determine What Electric Brake System Works With My Trailer
    Nowadays you would be able to find the axle capacity stamped on your axles, but that was not always the case. If you are unable to find that information on your axles, you still have other options. The first thing I would do is try to determine the make and model of your trailer, since you already know the year, and contact the manufacturer. A picture of the trailer and/or a description might help determine the axle you have on your trailer. If that does not work, there is one more option,...
