Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Tools Required: Jack and jack stands, OBD-II scanner, brake fluid, socket set, torque wrench.

2. Check and Refill Brake Fluid

Locate the brake fluid reservoir under the hood.
Remove the cap and check the fluid level; it should be between the minimum and maximum marks.
If low, top up with the recommended brake fluid type (DOT 3 or DOT 4).
Replace the cap securely.

3. Inspect Brake Components

Raise the vehicle using a jack and secure it with jack stands.
Remove the wheels to access the brake assembly.
Inspect brake pads for thickness; replace if below 3mm.
Check rotors for scoring or excessive wear; replace if necessary.
Tools Required: Socket set for wheel removal.

4. Check for Leaks

Visually inspect the brake lines and hoses for any signs of leaks or damage.
If leaks are found, replace the affected lines or hoses.
Tools Required: Wrench set for line replacement.

5. Reset the Brake Warning Light

After addressing any identified issues, connect the OBD-II scanner to the vehicle's diagnostics port.
Clear any error codes related to the brake system.
Start the vehicle to check if the brake warning light is still illuminated.
