Converting from hydraulic to electric brakes. Currently have a Dico 15638 10inch 5x41/2 drum need to buy electric brake drum to replace the Dico. Which drums can I use, not sure what my bearing specs are.

I have attached a link to a helpful article that explains what is needed to add electric drum brakes to a trailer.

Your Dico brake assemblies are 10 inch by 2-1/4 inch so the part # T4423400 and # T4423500 would both work as replacements.

The best way to make sure you get the right components is to pull the hub and get the bearings numbers from the side of the bearings as shown in the attached photo. If you cannot find the numbers on the bearings, I recommend using a digital caliper like part # PTW80157 and measure the axle spindle where the bearings ride and then measure the inside dimension of the hub.

After you have gotten the measurements let me know and I will be glad to make some recommendations that will work for you.
