Solution

1. Preparation

Gather tools: socket set, brake fluid, OBD-II scanner.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Wear safety gloves and goggles for protection.

2. Check and Refill Brake Fluid

Open the hood and locate the master cylinder reservoir.
Remove the cap and check the brake fluid level. If low, add the recommended brake fluid (DOT 3 or DOT 4 as per the vehicle specifications).
Replace the cap securely.

3. Inspect Brake Components

Lift the vehicle using a jack and secure it on jack stands.
Remove the wheel to access the brake components.
Inspect the brake pads for thickness; they should be at least 1/8 inch thick. Replace if worn.
Check the brake rotors for scoring or warping; machine or replace if necessary.

4. Check for Leaks

Inspect brake lines for signs of wear or damage.
Look for fluid leaks around the calipers and master cylinder.
If leaks are found, replace the damaged component or line.

5. Reset Brake Warning Light

After resolving any issues, use the OBD-II scanner to clear any fault codes.
Start the vehicle and verify if the brake warning light is off.
