  • Will Dexter 12-1/4" x 4" Brakes Fit in Place of Old Brakes with Stamped Backing Plate
    Provided that your existing brakes are 12-1/4" x 4" and use the same 7-bolt mounting pattern then you can use Dexter Electric Trailer Brake Kit # 23-438-439. I have included a link to a video review of this kit for you.

  • Availability of 10,000 lb Axle Dexter Trailer Brake Assemblies
    The only option we have for 10k axle rated Dexter electric brake assemblies is the part # 23-438-439 that you referenced. 10k trailer axles with drum brakes just aren't as popular as other options so there isn't as much competition for this size.

  • Brake Assembly for Dexter 10k Axle with 12 1/4 x 4 Brakes
    I have a solution for you but part # AKEBRK-10 is not what you are looking for. Instead the Dexter Electric Trailer Brake Kit Left/Right Hand Assemblies part # 23-438-439 is the set you need. The others are just a little too narrow for your application.

  • Replacement Brake Assemblies for Trailer with Dexter 10k Axles
    If you can measure the width of your current brake assembly pads I can get you the correct brake assembly set for your Dexter 10,000 lb axles. If the pads are 3-3/8 inches wide you'd want the part # 23-450-451 or if they are 4 inches wide you'd want the part # 23-438-439. I tried looking up the numbers on the tag you sent a picture of and was not able to find anything.

  • Brake Assemblies for Dexter 10k Trailer Axles of 1999 Eager Beaver
    Is there a capacity listed anywhere on the axle? I can give Dexter the serial number of your axle but it may take a couple days and if you could get me the diameter of your axles or the capacity I could much quicker get you what you need.

  • Electric Drum Brakes for 10K Axle Conversion from Hydraulic Brakes
    Your choice of electric drum brakes to replace your hydraulics will be based on axle weight capacity.

For example, Dexter Self-Adjusting brake set # 23-438-439 uses the same 7-bolt mounting pattern as the item you referenced, # AKEBRK-10R, but will properly fit your drums.

  • Recommended Brakes, Bearings and Seals for Dexter 10k General Duty Axle
    I reached out to Dexter and found that your axle is a 10,000 lb general duty axle. The correct inner bearing and race is the # 387A and # 382A, the correct outer bearing and race is the # 25580 and # 25520. For a replacement seal you want the # 10-51. For electric brakes I recommend the Dexter Electric Trailer Brake Kit - Self-Adjusting - 12-1/4" - Left/Right Hand Assemblies - 10K # 23-438-439. These are self-adjusting brakes so there will be no need for manual adjustment. I have attached...

  • Replacement Hub/Drums and Brake Assemblies for Dexter 10k Trailer Axle
    Since your trailer has Dexter 10k axles the correct hub/drum you need is the part # 8-430-5UC3 which comes with bearings, races and seal. Since you need shoes and magnets it would be easiest to go with new assemblies altogether like with the part # 23-438-439. Otherwise for shoes you'd need the part # BP04-325 for the left hand side and # BP04-335 for the right hand side. Then for a replacement magnet # BP01-301.
