INSPECT COMPONENTS
Make sure that the mounting conditions (looseness, backlash, etc.) of each component are normal.
Check the following:
–Device assembly for bend, damage and cracks. Replace if there are.
–Cables and equalizer for wear and damage. Replace if there are.
–Parking brake switch. Replace if it does not work correctly.
ADJUSTMENT
