  4. Release Tension:
    • Release the tension on the parking brake cable by loosening the adjusting nut or bolt at the handbrake lever inside the vehicle’s cabin.
  5. Disconnect the Cable:
    • Scollegare il cavo del freno di stazionamento dalle pinze o dai tamburi dei freni posteriori. Potrebbe essere necessario rimuovere le clip di fissaggio o gli elementi di fissaggio.
  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:
    • Route the new parking brake cable through the same path as the old one.
    • Fissare il cavo in posizione con clip o staffe e assicurarsi che segua il percorso originale.
  8. Connect to Rear Brakes:
    • Reconnect the parking brake cable to the rear brake calipers or drums. Use new grommets or clips if necessary.
  9. Tension the Cable:
    • Use a brake cable tensioning tool to adjust the cable tension. Consult your service manual for the proper tensioning procedure.
  10. Test the Brake:
    • After connecting the cable, test the parking brake to ensure it engages and disengages correctly.
  11. Adjust the Handbrake Lever:
    • Adjust the handbrake lever inside the vehicle to the appropriate tension.
  12. Controllare il corretto funzionamento:
    • Con il veicolo ancora sollevato in sicurezza sui cavalletti, assicurarsi che il freno di stazionamento tenga saldamente in posizione il veicolo.
  13. Lower the Vehicle:
    • Once you’re satisfied with the cable installation and parking brake function, carefully lower the vehicle to the ground.
