To determine which brake assembly you need, measure the width of your brake linings, as shown in the photo I edited for you.

If your existing brake shoes measure 4 inches wide, the # 23-438 you mentioned would be an example of a good replacement for you if your existing brake assemblies use 7 mounting bolts (some use 4) and the diameter of the assembly is 12-1/4 inches in diameter when measured from the outside of one brake shoe directly across to the outside of the other shoe as shown in the photo. If this is indeed the correct replacement assembly for you, you would also need the right hand assembly, # 23-439. You will also need the mounting hardware which is not included with the assembly. You will need 7 each of the following for each brake assembly:

Mounting bolt, # 7-5
Split lock washer, # 38LW
Nut, # 38N

If your existing brake assembly uses the 7 bolt flange, and the brake shoes measure 3-3/8 inches wide, you would need # 23-450 for the right side and # 23-451 for the left. The same mounting hardware mentioned above would apply.

The brake assembly you referenced, Dexter 12-1/4 x 4-Inch Left-Hand Electric Brake #23-438, is indeed rated for 10K axles. This brake matches up to Right-Hand brake #23-439. You can check for fit on your existing axle's brake flanges by checking…

Yes, I spoke with my contact at Kodiak and I sent him the picture you submitted to us and told him what axle setup you have and he said that the Kodiak Disc Brake Kit part #K2HR12A11-120DW will fit and work well. It will fit with 16 inch wheels on an…

An easy way to tell if your hubs were originally oil filled or packed with grease is to remove the cap of the hub. Typically, if it is a press-in cap it is a grease hub, and if it is a screw-in cap it is an oil bath hub. Not only do semi trailers use…

I did some checking and the hub/drum we offer that will work for you is the part #8-430-5UC3. This uses the same bearings as the 8-415 and will be an exact fit aside from the fact this is a non-ABS setup and the 8-415 came in an ABS setup and non-ABS…

Since you have a wheelbase/axle spacing of 38 inches the correct hanger kit for slipper springs would be the part #HAP-105-205-01. And then for a 7k trailer axle the u-bolt kit you'd want would be the part #APUBR-8. I attached the diagram to use…
