Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is parked on a level surface.
Engage the parking brake for safety.

Tools Required:

Brake fluid (DOT 3 or DOT 4 compatible with your vehicle)
Brake bleeder kit (or a clear plastic hose and catch container)
Wrench or socket set (for bleeder valves)
Funnel
Gloves and safety glasses

2. Access the Brake Fluid Reservoir

Open the hood and locate the brake fluid reservoir.
Remove the cap carefully, wiping it clean with a lint-free cloth to prevent contamination.

3. Remove Old Brake Fluid

If using a brake bleeder kit, attach it to the bleeder screw on the farthest brake caliper from the master cylinder.
Open the bleeder valve slightly (usually a 10mm or 12mm nut) and pump the brake pedal slowly to draw out old fluid into the container.
Repeat this process until clean fluid is seen flowing through the tubing.
Close the bleeder valve securely before releasing the brake pedal.

4. Fill with New Brake Fluid

Using the funnel, pour new brake fluid into the reservoir until it reaches the "MAX" line.
Replace the reservoir cap securely.

5. Bleed the Brake System

Move to the next brake caliper and repeat the bleeding process (from farthest to closest to the master cylinder).
Ensure that you keep checking the fluid level in the reservoir and refill as necessary to prevent air from entering the system.
Once all calipers have been bled, make sure all bleeder valves are tightened.

6. Final Checks

Inspect the reservoir for any leaks after replacing the cap.
Clean up any spilled brake fluid as it can damage car paint.
