Solution

1. Preparation

Gather necessary tools and safety equipment.
Ensure the vehicle is parked on a level surface and the ignition is off.
Wear safety goggles and gloves.

2. Check Brake Fluid Level

Open the hood and locate the master cylinder reservoir.
Inspect the brake fluid level; it should be between the "MIN" and "MAX" marks.
If low, top off with the manufacturer-recommended brake fluid (DOT 3 or DOT 4, depending on the specification).

3. Inspect Brake Pads and Rotors

Safely lift the vehicle using a jack and secure it on jack stands.
Remove the wheel to access the brake assembly.
Visually inspect the brake pads for thickness (minimum thickness should be 3 mm) and check for any uneven wear.
Check the rotors for scoring, warping, or excessive wear.
Replace any worn pads or rotors as necessary.

4. Examine Brake Lines and Hoses

Visually inspect all brake lines and hoses for signs of leaks, cracks, or corrosion.
Tighten any loose connections and replace damaged lines or hoses immediately.

5. Check ABS System Components

Inspect the ABS sensor wiring and connectors for damage.
If error codes related to the ABS are present, follow the manufacturer's specifications to diagnose and resolve those issues.

6. Reassemble and Test

Reinstall the wheel and lower the vehicle.
Start the engine and check if the brake warning light is still illuminated.
Test drive the vehicle at low speeds to ensure proper brake function.
