How to Pick Out Replacement Brake Assembly to Replace One with Broken Mounting Studs


I removed the brake unit from one wheel on my FW RV trailer today and all of the studs that secure it to the axle sheared off. What part do I need to repair this. It all seems intact but with the studs absent.


Expert Reply:

It's time for a new brake assembly since you broke off all of the mounting studs of your old one.

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 # 40716 is a 10 inch by 2-1/4 inch thick brake assembly.

You also want to determine what the bolt pattern is of your assembly mounting flange. The standard size is 4 on 4 inch. You also want to determine the axle capacity of your trailer and go with an assembly that has the same rating, the # 40716 has a 3,500 lb capacity.
