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.


High-Quality Brake Pads

Riveted brake pads will always give you a screeching reminder to replace your brake shoes. That's because the rivets will scrape against your drum as the friction material wears down. You won't have that noisy problem with bonded brake pads. You'll also get a little more friction pad contact because there aren't any cutouts for rivets. And more friction means more stopping power.


A close-up shot of a drum brake shows a tapered brake pad.

These pads are also tapered, which should help to prevent any broken, crumbly bits of material from rotating inside the drum as the pads wear over time. Brakes without these tapers are more likely to create a jarring braking experience that could cause the brakes to stutter and lock up.


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.

    Yes, The Dexter Electric Trailer Brake Kit - Self-Adjusting - 12 inch - Left Hand and Right Hand - 8K # K23-532-533-00 will work with your Hayes 8k 4 bolt axle.

  • Brake Assembly for 12 Inch Brake Drum With 4-Bolt Mounting Pattern
    Is there any tag or label on your axle that would help identify it? You could possibly have a AL-KO/Hayes axle that used a 4 bolt pattern that measured as follows: • The top two holes are 3-1/8 inches apart • The bottom two holes are 2-1/2 inches apart • The top row of holes is 3-3/8 inches apart from the lower holes I've provided a photo showing these dimensions. If the spacing matches up, and your existing brake drums are 2 inches deep, the # 23-105-106-09 brake assemblies would be...

  • Are Trailer Brakes Interchangeable Between 7k and 8k Axles
    There is a size difference between the brake assemblies that fit 7k axles and 8k axles so you would not be able to use 7k assemblies on an 8k axle. You'll have to measure your current assemblies do determine which kit you'd need: # K23-532-533-00 for 12 inch by 3-3/8 inch # DX32QR for 12 1/4 inch by 2-1/2 inch # 23-434-435 for 12-1/4 inch by 3-3/8 inch

  • What Size are Dexter Electric Brakes for 8,000 lb AL-KO/Hayes Axles
    I checked the sizes for you, and both of these electric brakes are in fact 12" diameter x 3-3/8" wide: - Left Hand Side: Dexter Electric Trailer Brake Assembly # K23-532-00 - Right Hand Side: Dexter Electric Trailer Brake Assembly # K23-533-00 They also come in a set, the Dexter Electric Trailer Brake Kit # K23-532-533-00 These are a only a fit for the 4-bolt mounting flange on 8,000 lb AL-KO / Hayes axles.

  • Replacement Hub and Drum/Brakes for AL-KO 8k Axle
    I ran that through the Dexter cross reference for AL-KO parts and it did not come back as anything. If you're looking for replacement brakes the # K23-532-533-00 will fit as long as you have a 12" x 3-3/8" drum. This will match the 4-bolt brake flange pattern since it is designed for AL-KO. If you're looking for a replacement hub and drum assembly the # DX46XR will work as long as you have a # 25580 inner and # 02475 outer bearing.

  • Replacement Brake Assembly and Oil Seal for Dexter 00828510 Brake Drums
    It looks as if you have the # 8-285-10UC3-A Dexter Oil Bath hubs. Thanks for sending the photo! Those hubs take a 12 x 3-3/8 inch brake assembly, I'd recommend a self-adjusting brake assembly kit like # K23-532-533-00 which are compatible with a 4 bolt brake flange. This includes the right and left brake assembly. The correct oil seal for your hubs is # 10-63, which has a 2.25 inch ID and a 3.376 inch OD.

    To get the correct replacement brake drums for your 8,000 pound axles, you will need a few things to be verified. The first will be if they are are hydraulic or electric brakes.

  • Brake Assemblies For 8,000LB Trailer Axles
    Having 8,000lb axles you are going to need either the 12-1/4" X 3-3/8" Electric Trailer Brake Kit # AKEBRK-8 or the 12" X 3-3/8" Dexter Electric Trailer Brake Kit # K23-532-533-00. The 12" X 3-3/8" Dexter kit is what is generally used on older AL-KO / Hayse axles. If you are unsure you can check your axles for any identifying marks or measure the diameter of your current brake drums. The Electric Trailer Brake Kit # AKEBRK-6 you found is only for 5,200-7,000lb axles with a 5 bolt brake flange.
