Harley-Davidson has decided that a defect which relates to motor vehicle safety exists on certain model Street motorcycles brake calipers. See below for year, model. These brake calipers may experience corrosion in the caliper bore area if subjected to a corrosive external environment over time, especially in coastal environments or coastal environments where road salt is used. This corrosion could result in the pistons dragging in the caliper bore. If this condition remains undetected it could lead to increased brake drag, possibly resulting in a crash.
