There is a very good chance that wheel is doing the braking while at least one of the others is not working. Have you checked the amperage draw and voltage at each magnet? Each magnet should draw 3A when energized per
Dexter Axle. (scroll down to "brakes") A better description may be found
here.
While some folks curse electric brakes they are a good, safe, design-when properly maintained.
Boeing is using electric brakes on their new 787, and
Bombardier (Canada) is testing electric brakes on an aircraft.
