Which Hub Drums and Brake Assemblies for 3500lb Axle on Utility Trailer


I have a single axle utility trailer with regular hubs (no brakes). The trailer does have the 4-hole brake flanges, and its got a 3500 lb axle. The inner bearing is L68149 and the outer is L44649. I don't have the grease port on the spindle, so I think I need the AKHD-545-35-K. Can you confirm this? Which brake assembly do you recommend? I've got the wiring run already, so that's ok.

It sounds like you have a pretty good handle on what you need. If your existing hubs use the 5 lug on 4-1/2 inch bolt circle, and the surface of your spindle where the grease seal rides is around 1.719 inches, the # AKHD-545-35-K is the proper hub/drum.

You can go with standard brake assemblies, like # AKEBRK-35L for the left side and # AKEBRK-35R for the right. However, I'd recommend going with self adjusting assemblies like part # AKEBRK-35R-SA or the right sided and # AKEBRK-35L-SA for the left. As the brake pads wear, the assemblies will self-adjust so you'll always have optimal braking performance. Please note, the mounting hardware and adjuster hole plugs aren't included. The brake assemblies have the mounting studs integrated into the back of the assembly, but for each assembly, you'll need 4 nuts, part # 6-17 and 4 lock washers, part # 5-8.
