Convert Air to Electric Brakes
Hello all,,,, first time here.
I'm helping my cousin convert Air brakes to electric. Most of it is nothing new to us. Except the drums that are on the trailer now,, do not have the flat surface needed for the magnet to make contact. But it looks as though there are "pre threaded" holes for mounting a plate/disc inside the drum. Am I correct in assuming this?? And if so,,, where can I find the plate/disc for it??
Here is a pic of the drum,,, and I circled the threaded holes to help.
(Wisconsin Trailer,,, 12 1/4 drum size)
