Solution

1. Preparation

Gather tools and materials: OBD-II scanner, brake fluid, socket set, jack and jack stands, and safety goggles.
Ensure the vehicle is on a flat surface and the engine is turned off.
Disconnect the battery before working on the braking system for safety.

2. Check Brake Fluid

Open the hood and locate the brake fluid reservoir.
Remove the reservoir cap and check the fluid level.
If low, top off with the recommended brake fluid type (DOT 3 or DOT 4) as specified in the owner's manual.
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 (should be at least 3 mm) and check for uneven wear.
Check the rotors for scoring or warping.

4. Examine Brake Lines

Inspect all brake lines for leaks, cracks, or corrosion.
If any damage is found, replace the affected brake line using a suitable replacement part.
Bleed the brake system to remove air from the lines.

5. Test Brake Light Switch

Locate the brake light switch near the brake pedal.
Disconnect the switch connector and test continuity using a multimeter.
If defective, replace the switch with a new one and reconnect it.
