  5. Disconnect the Cable:
    • Disconnect the parking brake cable from the rear brake calipers or drums. This may involve removing retaining clips or fasteners.
  6. Remove Old Cable:
    • Trace the cable’s path and remove any clips or brackets that secure it to the vehicle’s chassis or body.
    • Carefully remove the old parking brake cable from its routing.
  7. Install New Cable:
