It sounds like you need the brake mounting flange that needs to be welded to the axle.

You will need to know the diameter of your axle to make sure you choose the correct brake mounting flange. If you have a 1-3/4 inch round 2,000 lb axle, the brake flange you need is part # 4-34. This has a 4-bolt mounting pattern with a center hole that measures 1.64 inches diameter. This will work with 7 inch brake assemblies like part # 23-398 for hydraulic and part # 23-48 for electric brakes.

If you have a different size axle let me know the size and diameter and I can make some recommendations that will work for you. If you need the brake assemblies, drums, hubs or other components just let me know what kind of brakes you need.
