Question:

I have a 2004 12 Ton Econoline Backhoe Pro trailer. It has the 4 axle multimax independent axel system with 8 lug wheels. The specs online state #5000 axles with 12”x2” Brakes and 14.5 wheels. It has 8 brake drums total. What electric brake setup would be best for me?

Expert Reply:

If you have 12" x 2" brakes and are needing to replace them only then we have exactly what you are looking for.

Our Electric Trailer Brake Kit # AKEBRK-7-SA includes left and right self adjusting brake assemblies that have a 12" diameter and are 2" wide. They are compatible with 14-1/2", 15", 16", and 16-1/2" wheel sizes and 5,200 lbs, 6,000 lbs, and 7,000 lbs axles so they will work for your application.

If you are needing to replace your hub and drum assemblies as well then you will need to change out your tires and wheels as the sizes you have are not typical. This may be beneficial for any future repairs or if you need spare parts.

If you are wanting to stick with 14-1/2" wheels then we have the Dexter Trailer Hub and Drum Assembly # 8-201-9UC3-EZ which is rated for 5,200 lb - 6,000 lb axles, has a 6 on 5-1/2" bolt pattern, and is compatible with the above mentioned brakes. Since your axles are rated for 5,000 lbs you may want to measure the B, C, and D parts of your spindle (see attached picture) to make sure that this assembly is compatible with your spindle. If B measures 2.125", C measures 1.75", and D measures 1.25" then you are good to go. Otherwise let me know what those measure and I can see what we have.

Since you have 8 lugs on your current wheels they will not be compatible with this hub and drum assembly. I recommend going with the Westlake ST225/75R15 Radial Trailer Tire w/ 15" Silver Mod Wheel # LHAW124. This has the same 6 on 5-1/2" pattern that the previously mentioned hub and drum assembly has and it comes in a load range of E (2,830 lbs at 80 psi). This tire has a slightly larger diameter at 28.3" as compared to the 27.7" diameter of your current tires. This puts the tire about 1/4" closer to the underside of your trailer so you will want to make sure there is enough clearance.
