Question:

We bought a used stock trailer and all parts houses in our town are having trouble getting replacement brake backing plates. I’m hoping the backing plate part number 23-106-09/23-105-09 with work for me.

I can help you find the right assemblies, but I do not know exactly which ones you have on your trailer.

To pick out the correct brake assemblies for your trailer you need to know a few things.

You will want to measure the inner diameter of your hub/drums and the depth of the drums to determine what brake assembly dimensions you need. For example the part # 23-105-09 is a 12 inch by inch thick brake assembly.

You also want to determine what the bolt pattern is of your assembly mounting flange. The standard size is 5 bolt. You also want to determine the axle capacity of your trailer and go with an assembly that has the same rating, the # 23-106-09 and # 23-105-09 are both 6k
