Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, brake fluid, brake cleaner, and a torque wrench.
Ensure the vehicle is on a level surface and securely supported with jack stands.
Disconnect the battery before working on the brake system.

2. Inspect and Replace Brake Fluid

Remove the brake fluid reservoir cap.
Check the fluid for contamination (cloudiness). If contaminated, proceed to replace.
Use brake cleaner to clean the area around the reservoir before opening.
Siphon out the old fluid and refill with new brake fluid (DOT 3 or DOT 4 as per manufacturer specifications).
Replace the reservoir cap and ensure it is secure.

3. Inspect Brake Components

Remove the wheel to access the brake components.
Check the thickness of the brake pads; replace if below 3mm.
Inspect the rotors for scoring or excessive wear; replace if damaged.
Ensure the brake calipers are functioning properly and not seized.

4. Bleed the Brake System

Attach a clear hose to the bleeder screw on the brake caliper.
Have an assistant pump the brake pedal several times, then hold it down.
Open the bleeder screw to allow air and fluid to escape, then close it before the pedal is released.
Repeat until no air bubbles are visible in the fluid, and then tighten the bleeder screw.

5. Check Brake Warning Light Circuit

Inspect the connectors and wiring leading to the brake warning light for any damage or corrosion.
Clean or replace any faulty connectors.
Reconnect the battery and check if the warning light has cleared.
