Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to prevent electrical short circuits.
Ensure the vehicle is on a flat surface and securely supported.

2. Inspect and Clean Components

Remove the rear wheels to access the brake components.
Inspect the electronic parking brake calipers for any visible damage or debris.
Clean the caliper mechanisms and ensure no dust or rust is present that could interfere with operation.

3. Replace Components (if necessary)

If the caliper is found to be defective, replace it:
1. Disconnect the caliper mounting bolts using a socket wrench.
2. Carefully remove the caliper from the rotor.
