Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, brake fluid, brake pad spreader, and safety glasses.
Park the vehicle on a level surface and engage the parking brake.

2. Check Brake Fluid Level

Open the hood and locate the brake master cylinder.
Inspect the fluid level; if it’s below the minimum line, top it up with the appropriate brake fluid (DOT 3 or DOT 4 as specified by the manufacturer).
Close the cap securely.

3. Inspect Brake Components

Remove the wheel using a socket set.
Visually inspect brake pads for thickness; replace if they are worn down to 3mm or less.
Check the rotors for scoring or warping; replace if necessary.
Reinstall the wheel and torque to manufacturer specifications (usually around 80-100 ft-lbs).

4. Address Any Leaks

Examine brake lines and hoses for any signs of leakage or damage.
Replace any damaged components and ensure all fittings are secure.

5. Clear Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Retrieve and note any DTCs related to the braking system.
Clear the error codes and observe if the brake warning light returns after the repair.
