Magnets
Your electric brakes are equipped with high quality electromagnets that are de-
signed to provide the proper input force and friction characteristics. Your magnets should
be inspected and replaced if worn unevenly or abnormally. As indicated below a straight-
edge should be used to check wear.
Even if wear is normal as indicated by your straightedge, the magnets should be
replaced is any part of the magnet coil has become visible through the friction material
facing of the magnet. It is also recommended that the drum armature surface be refaced
when replacing magnets. Magnets should also be replaced in pairs (both sides of the
axle). Use only genuine Dexter replacement parts when replacing your magnets.
