Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, brake fluid, multimeter, brake pad spreader.
Park the vehicle on a level surface and turn off the ignition.
Disconnect the negative battery terminal to ensure safety while working on the brake system.

2. Check and Refill Brake Fluid

Locate the brake fluid reservoir under the hood.
Remove the cap and check the fluid level; if it’s below the "MIN" line, clean the area around the cap to prevent contamination.
Fill with the appropriate brake fluid (DOT 3 or DOT 4 as specified in the owner’s manual) to the "MAX" line.
Reinstall the cap securely and reconnect the battery terminal.

3. Inspect and Replace Brake Pads (if necessary)

Remove the wheel using a socket set to access the brake assembly.
Inspect brake pads for thickness; replace if they are less than 3mm.
If replacement is needed:
- Use a brake pad spreader to compress the caliper piston.
- Remove caliper bolts and detach the caliper from the rotor.
- Replace old pads with new ones, ensuring proper orientation.
- Reattach caliper and torque bolts to manufacturer specifications (typically around 25-35 ft-lbs).
Reinstall the wheel and torque lug nuts to specification.

4. Test the Parking Brake

Ensure the parking brake lever is fully released.
If the warning light persists, inspect the parking brake switch for proper operation.
Adjust or replace the switch if necessary.
