Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is parked on a flat surface and engage the parking brake.
Tools Required: Jack and jack stands, socket set, brake fluid, OBD-II scanner, multimeter.
Safety Warnings: Always wear safety glasses and gloves. Ensure the vehicle is securely supported on jack stands before working underneath.

2. Check and Refill Brake Fluid

Locate the brake fluid reservoir, usually near the driver's side rear of the engine bay.
Remove the reservoir cap and check the fluid level against the markings.
If the fluid is low, add the recommended brake fluid (DOT 3 or DOT 4 as specified in the owner’s manual) until it reaches the proper level.
Replace the cap securely.

3. Inspect for Leaks

Visually inspect the brake lines, master cylinder, and brake calipers for any signs of fluid leaks.
If any leak is found, trace the source of the leak.
For minor leaks, you may need to replace the damaged section of the brake line or component. For major leaks, replace the affected parts.

4. Brake Pad and Rotor Inspection

Remove the wheel to access the brake components.
Inspect the brake pads for wear; replace if they are below the minimum thickness (typically 3mm).
Examine the brake rotors for scoring or warping; if damaged, resurface or replace them.

5. Reset the Brake Warning Light

After addressing all issues, if the brake warning light remains illuminated, use an OBD-II scanner to clear any error codes.
Disconnect the battery for a few minutes, then reconnect to reset the vehicle’s computer.
