    The Dexter Electric Trailer Brake Kit # 23-434-435 referenced in your question is designed for 8,000 pound axles.

  • What is Mounting Bolt Pattern of Dexter Brake Assemblies # 23-434-435
    I attached a picture that shows the 4 bolt mounting pattern of the brake assembly part # 23-434-435 which is 2-7/8 inches left to right and 4 inch accross. Keep in mind these are designed for 8,000 lb axles. For 9,000 to 10,000 lb axles, you'd want to use part # 23-450 and # 23-451. These use a 7 bolt mounting pattern.

  • Testing Trailer Magnets On A Trailer With 12" Electric Drum Brakes
    I have linked an article below on testing brake magnets for you to reference. You will need a Multimeter # PT89ZR to test the magnets in the Dexter Electric Trailer Brake Kit # 23-434-435. First you will begin by testing the output coming from the vehicle. Each magnet should see 3.2-4.0 amps of power between 12-13 volts with the brake controller set to max. This test can also be performed with a 12v battery to determine if the problem is with the brake controller or wiring and not...

  • Converting Hydraulic Brakes To Electric On Tri-Axle Livestock Trailer

The 10,000 lb axle 12-1/4 inch diameter Dexter hub and drum assembly part # 8-430-5UC3 that we carry is hydraulic and electric brake compatible which may be what you have. If you can tell me the part number of the Dexter hubs and drums you have specifically I can find out if they are compatible. If your hubs are compatible, I recommend Dexter Electric Brake Kit part # 23-434-435. These Dexter brakes measure 12-1/4" diameter...

  • Will etrailer.com 12-1/4 inch by 3-3/8 inch Brake Assemblies Replace Dexter Brand
    For your Dexter drums that take assemblies that are 12-1/4 inch by 3-3/8 inch our etrailer.com brand asssembly set part # AKEBRK-10 is a confirmed fit and will save you money over the Dexter kit # 23-450-451. These are both kits for 10k axles. If instead you have 8k you'd need # AKEBRK-8 for etrailer.com brand and # 23-434-435 for Dexter.

  • Do Electric Brakes Need Certain Amount of Stopping Power?
    That isn't the sort of figure that is factored into brakes. What you need to choose the right brakes is your axle's capacity, which is going to lead you in the right direction in terms of the brakes you need. For example, a 3,500 lb axle capacity would need electric brakes # AKEBRK-35-SA whereas an 8,000 lb axle would use # 23-434-435.

  • 8k Rated etrailer Hub/Drums that Work as Replacement for Dexter 8-285 Hub
    Yes the etrailer hub/drum # AKHD-865-8-K that you referenced would work great as a replacement for the Dexter 8-285 hub part # 8-285-10UC3-A that you also mentioned. Then for a set of brake assemblies we have the self adjusting Dexter kit part # 23-434-435 which would work great or the etrailer equivalent part # AKEBRK-8.

  • How to Determine Correct Bearings, Seals, and Electric Brakes for Hub and Drum
    I was unable to find a reference to that axle, but there is a simple way to find out the exact replacement bearings and seals you need. Simply take apart your hub assembly and look at the bearings themselves; wipe away the grease and you should be able to see the part number stamped directly on them. If you are unable to find them, you need to use Digital Caliper # 301-17068 and measure your spindle to the thousandths of an inch where the bearings ride, as well as where the grease seal...
