Ask the Experts about this Dexter Axle Trailer Brakes



  • Is Dexter Electric Trailer Brake Kit for 7,200 lb Axles for One Axle or Two
    The Dexter Electric Trailer Brake Assembly - 12-1/4" - Left Hand # 23-428 is just one left hand brake assembly; the other side is the Dexter Electric Trailer Brake Assembly - 12-1/4" - Right Hand # 23-429. That is for one axle, and you can order them as a unit with the Dexter Electric Trailer Brake Kit - 12-1/4" - Left and Right Hand Assemblies - 7,200 lbs # 23-428-429. For an adjustment spoon you will need the Brake Adjustment Spoon for Drum Brakes # W80630, and the correct mounting...

  • Electric Trailer Brakes for 6,000 lb or 7,200 lb Axle
    The only way to know for sure what the capacity is of your axle is to contact the manufacturer with the serial number, but since you said they are 3 inch round axles, you are correct they will almost certainly be either 6,000 lb, 7,000 lb, or 7,200 lb axles. We can actually get you set up with new electric brakes based on the size of your hub and drum. You just need to measure the inside diameter and depth of your drum, as well as know the brake flange mounting bolt pattern to be sure....

  • Parts Needed to Add Brakes to Mobile Home Axle
    From the measurements you mentioned it sounds like you have a spindle that could be compatible with a hub and drum like the Dexter 8 on 6-1/2 # 8-393-6UC3-A, but by the time that you added a brake assembly like the # 23-428-429 you'd more than likely save yourself time, money and work by completely replacing the axle. If you wanted to just replace the hubs and add brakes, to confirm which hubs and brakes you'll want to use, you'll need to match the bearings on your current hubs. The Dexter...

  • Trailer Brakes Compatible with 12x2 inch or 12-1/4x2-1/2 Inch Hubs
    We have a fit for 12x2 inch hubs or 12-1/4x2-1/2 inch hubs. The Dexter Electric Trailer Brake Kit - 12-1/4" - Left and Right Hand Assemblies - 7,200 lbs # 23-428-429 is the only fit we have for the larger hubs and it has a 4 bolt versus 5 bolt brake flange connection, but we have both electric or hydraulic options for the 12x2 inch hubs. I've linked the page to all those options.

  • Mounting Hole Pattern for Dexter 12 x 2 Electric Drum Brake 23-105-09
    Most of our 12 x 2 electric drum brake assemblies like Dexter left/right kit # 23-112-113 use a 5-bolt mounting pattern but the Dexter brake kit # 23-105-106-09 has both 4-bolt and 5-bolt mounting holes. I went to our warehouse and measured the spacing of the 4 bolt holes. You can see this center-to-center hole spacing in the photo I prepared for you. Please note that we do have a brake in a similar size, 12-1/4 x 2-1/2, for a 7200-lb axle that uses a 4-bolt pattern. This is brake set...

  • Mounting Bolt Pattern for Dexter 12-1/4 x 2-1/2-Inch Electric Drum Brake Assemblies
    All of our 12-1/4 x 2-1/2-inch brake assemblies use a 4-bolt mount. These appear on the linked page. We have none with a 9-bolt flange mounting pattern. I did check with several of our install and technical staff and I learned that some brake assemblies will use a backing plate that has extra holes, holes not intended for mounting purposes.

  • Testing and Replacing Brakes on a 2012 Carriage Cameo Trailer
    I've attached an article to help you test the magnets. You also should inspect the wiring for the brake that's giving you issues. If you need to replace the brake you don't have to do both. However, it might be easier in the long run and if the others are showing wear it's a good idea. It can save you time and money later. To determine which brakes to get you can measure the inside diameter of your drums. If they're 12 inch drums then I recommend using # AKEBRK-7-SA. These are self-adjusting...

  • Is The Distance Between Races On Dexter Hub 8-285-11 and 8-393-6UC3-A The Same?
    I had our warehouse measure the distance between the inner and outer races of the Dexter Trailer Hub and Drum # 8-285-11 and # 8-393-6UC3-A and they found that both of them have the exact same 1-3/4" measurement, so as long as you have the # 25580 inner bearing and # 02475 outer bearing combination either hub will fit fine. You will just need to match the hub to the correct brake assemblies as the # 8-285-11 uses 12-1/4" x 3-3/8" brake assemblies # 23-434-435 where the # 8-393-6UC3-A uses...

  • Replacement Hub and Drums For PJT Trailer With 008-393-03 Installed
    Thanks for all of the information on your PJT Trailer! Based on your drum part number you have a 12-1/4" Drum that is oil bath. The Dexter # 8-393-4UC3 is almost right, but it is designed for grease and not oil. You will need the # 8-393-4UC3 and oil seal # 10-63 for each hub. This hub does not include the bearings so you will also need new inner bearing # 25580 and outer bearing # 02475 for each hub. If you need replacement brakes now or in the future you will need # 23-428-429 for...
