When they are worn down to the little screw heads? Is there a finite thickness measurement?
Help would be gratefully accepted.
When round magnets wear down to the TOP
of the 3 brass screws, there done.
If you go beyond that, they will wear into the wire coil.
When that happens, you will have an electrical short facing the controller.
Then, anything can happen.
An electrical short, of any kind, is never OK.
