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.

  • Parts Needed to Convert Dexter 15k Air Brakes to Electric Brakes
    What you'd need to convert your 15k Dexter air brakes to electric brakes is just new electric brake assemblies part # 23-446-447 to replace the air brake assemblies you have now. I checked with Dexter and the drum you have now will work fine with these assembly replacement. You'd be able to pull off all of the air brake components you have now and replace everything with basically just wires that lead back to the brake drum magnets with 10 gauge wire like part # 10-1-1 which is sold by the foot.

  • Is There a Way to Tell Difference Between 12k and 15k Trailer Brake Assemblies
    12k trailer brake assemblies like the part # 23-442-443 and 15 assemblies like part # 23-446-447 can both be 12-1/4 inch by 5 inch and use the same 7 bolt mounting pattern so dimensionally it's hard to say. I would look for part numbers on your assemblies to see if you can determine it that way or you could look on the axle for a capacity listed. The big difference between the two will be magnet sensitivity as the higher rated assemblies will need a magnet that grabs a little harder....

  • Replacement Brakes For Gooseneck Trailer With Heavy Axles

  • Replacement 12-1/4 x 5 Brake Assemblies For a 15,000LB Dexter Axle
    Currently Dexter only offers 12-1/4" x 5" brakes with a 7-Bolt mounting flange. I do see Dexter does offer a mounting flange 004-048-00 which you can get to update your axle to the 7 bolt flange. We currently do not carry this but it will allow you to use either their Electric # 23-446-447 or Hydraulic # 23-406-407 brake assemblies.

    To confirm that the Dexter Electric Brake Kit # 23-446-447 will operate properly on your Dexter 15,000lb axle you will need to confirm that your hub is compatible with electric brakes. The Dexter Trailer Hub and Drum Assembly # DX78QR for a 15,000lb axle, you can see the smooth surface inside the drum where the mounting bolts are that confirms it will work with electric brakes. The only other parts you will need is some 12 Gauge Wire # 12-1-1 to run from the 7-way connector to the brakes...
