Solution

1. Preparation

Gather tools: jack, jack stands, socket set, screwdriver, and OBD-II scanner.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to avoid electrical issues.

2. Inspect and Adjust Parking Brake Lever

Remove any covers or trim around the parking brake lever.
Check for obstructions around the lever; clear any debris.
If the lever is stuck, apply lubricant to the pivot points and operate the lever several times.

3. Check Parking Brake Cables

Raise the vehicle using a jack and secure it with jack stands.
Locate the parking brake cables leading to the rear brakes.
Inspect for damage, rust, or disconnection; replace if necessary.

4. Inspect and Replace Parking Brake Shoes

Remove the rear wheels to access the brake assembly.
Inspect the parking brake shoes for wear; if they are worn down, replace them.
If replacement is needed, follow these sub-steps:
- Remove the retaining clips and springs.
- Install new parking brake shoes in reverse order of removal.
- Adjust the shoes to ensure they do not drag against the rotor.

5. Testing Electronic Parking Brake (if equipped)

Reconnect the battery and use an OBD-II scanner to check for error codes.
If codes are present, address the specific issues indicated (e.g., faulty motor or module).
Clear codes and test the electronic release function.
