I once had disks and pads replaced by a local garage and years later

Most brake pad warning systems show an error if the sensors aren't
connected.

That may be true of more sophisticated cars but the two Fords I had about 10
and fifteen years ago simply had a single wire that was open circuit until the
pad contact wore down to short it to earth. So they had no idea whether they
were connected.
