Wiring for the electric brake magnets were damaged on all 4 of the two axle set received, due to poor packaging. One of the 4 backing plate assy's. Required splicing a short length of wire to replace the portion pinched off. All 4 had pinched/damaged insulation, which I repaired beading shrink wrap over the damaged insulation areas.
None of this was a major concern, just was an unnecessary annoyance to have to repair the wiring on newly received parts.
