Brakes and Traction Control: Service Precautions
WARNING:
^ Do not re-use any fasteners that are worn or deformed in normal use.
^ Some fasteners are designed to be used only once, and are unreliable and may fail if used a second time. This includes, but is not limited to, nuts, bolts, washers, circlips and cotterpins. Always follow the recommendations-replace these fasteners with new parts where indicated, and any other time it is deemed necessary by inspection.
