  • Replacement Dexter Electric Brakes for Trailer with 9,000 or 10,000 Pound Axles
    For the axles on your trailer, I recommend the Dexter Electric Brake Kit # 23-450-451. These are self-adjusting brake assemblies that measure 12-1/4 inches x 3-3/8 inches. These particular brake assemblies are designed for 9,000-10,000 pound Dexter axles, so they will work great whether you actually have a 9,000 pound or 10,000 pound axle on the trailer. To ensure they will fit perfectly, you can take a couple of quick measurements on your existing drum to verify they are 12-1/4 inches...

  • Installing the Magnet Retainer Clip on a 10K Electric Brake
    The magnet clips # BP19005 should not be making contact with the drum while the brakes engage, so I do not think that is the problem. What I think is going on is it's just not seating all the way. These can get a little squished or deformed causing this to happen, so it is fairly common. When snapping in place, you definitely want to push it in harder than you would expect to. You should get a pretty solid click/snap when it is fully seated. You should be able to gently pull on the magnet...

  • Does the Oil Seal On a Dexter 10K Hub Need To Be Replaced After Removing
    I think you are asking if the oil seal must be replaced each time the drum is removed and if that is the case then no, the oil seal if in good condition can be reused. For replacement braking assemblies you can use the Dexter Electric Brake Kit part # 23-450-451 which are self-adjusting. If you just want to replace just the lining that is an option as well using part # BP04-255 and part # BP04-245.

  • 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.

  • Difference Between etrailer Electric Trailer Brakes And Dexter Electric Trailer Brakes
    The differences between the Electric Trailer Brake Kit w/ Dust Shields # AKEBRK-10 and the Dexter Electric Trailer Brake Assembly # 23-450 are the different manufacturers and that the # AKEBRK-10 have dust shields, and the # 23-450 does not. Also # 23-450 is just the driver side brake assembly, where # AKEBRK-10 includes the driver and passenger side brake assemblies. If you wanted the Dexter Kit you would need the Dexter Electric Brake Kit # 23-450-451 which includes both brake assemblies. Both...

  • Replacement Brake Assemblies for Dexter 10,000 lb Trailer Axles
    How is the adjustment of the assemblies? Typically the problem you are having is due to the assemblies not being adjusted properly. Ideally they are tight enough that there's a light drag as you turn them by hand. To see how to manually adjust trailer brake assemblies check out the video I attached, fast-forward to the 4:35 mark of the video. Since we know you have 10k Dexter axles the correct brake assemblies are the part # 23-450-451 for if you have an electric brake setup or part...

  • Correct Replacement for Dexter Hub/Drum 8-415
    I was able to cross reference the Dexter Hub/Drum 8-415 to the Dexter Trailer Hub Drum Assembly part # 8-430-5UC3 which should be an exact replacement. I don't have any depth measurements of the above/drum but what you would need to measure to confirm is the inside of the contact surface on the hub where the shoe rides and this should measure 12-1/4" x 3-3/8". If so, you should be good to go. In regards to braking assemblies, the best option we have is the Dexter Brake Kit part # 23-450-451...
