Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is on a level surface and securely elevated using jack stands.
  • Disconnect the negative battery terminal to prevent accidental electrical discharge.
2. Inspect and Test Parking Brake Components
  • Tools Required: Multimeter, socket set, brake cleaner.
  • Remove the rear wheel to access the parking brake assembly.
  • Inspect the parking brake cables:
    • Look for fraying or corrosion.
    • Check for binding by manually pulling on the cables.
  • If any issues are found, replace the damaged cables.
3. Check Parking Brake Switch and Module
  • Tools Required: Multimeter.
  • Locate the parking brake switch (typically near the center console).
  • Disconnect the switch connector and use a multimeter to check for continuity when the switch is engaged.
  • If the switch is faulty, replace it. If the switch is fine, inspect the electronic parking brake module for faults.
4. Brake Pad and Caliper Inspection
  • Tools Required: Brake tool set, torque wrench.
  • Inspect the brake pads and calipers for wear or seizing:
    • Remove the caliper and check for smooth operation.
    • Clean any corrosion from the contact points.
    • Replace any worn or seized components as necessary.
5. Reassemble and Adjust
  • Reinstall all components in reverse order.
  • Adjust the parking brake as per manufacturer specifications, ensuring proper tension.
  • Reinstall the wheel and lower the vehicle.
