Solution

1. Preparation

Tools Required: Safety glasses, gloves, brake fluid, brake cleaner, socket set, jack and jack stands.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Inspect Brake Fluid

Remove the brake fluid reservoir cap and check fluid levels.
If low, top off with the manufacturer's recommended brake fluid (DOT 3 or DOT 4).
Inspect for any leaks around the reservoir and lines.

3. Inspect Brake Components

Lift the vehicle using a jack and secure it with jack stands.
Remove the wheels to access brake components.
Inspect brake pads for thickness; replace if below 3mm.
Check rotors for grooves or warping; replace if necessary.
Inspect brake lines for cracks or leaks; replace any damaged sections.

4. Check Electrical Connections

Locate the brake light switch and ABS module.
Inspect wiring for damage or corrosion.
Ensure all connections are secure; clean any corroded terminals.

5. Clear Codes and Test Drive

Use the OBD-II scanner to clear any fault codes.
Test drive the vehicle to ensure the brake warning light does not re-illuminate and that braking performance is restored.
