Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety glasses and gloves for protection.

2. Inspect Brake Fluid Reservoir

Open the hood and locate the brake fluid reservoir.
Check the fluid level against the minimum and maximum markings.
If low, top up with the recommended brake fluid (DOT 3 or DOT 4).

3. Examine Brake Lines and Hoses

Follow the brake lines from the master cylinder to the wheels.
Look for any visible leaks, cracks, or corrosion.
If any damage is found, mark the area for repair or replacement.

4. Check Calipers and Wheel Cylinders

Remove the wheel for better access to the brake components.
Inspect the brake calipers and wheel cylinders for any signs of fluid leaking.
If leaks are detected, replace the affected caliper or wheel cylinder.

5. Inspect Master Cylinder

Check around the master cylinder for signs of fluid leakage.
If the seals are leaking, replace the master cylinder.

6. Replace Damaged Components

For any damaged brake lines, hoses, calipers, or wheel cylinders, replace them as necessary.
Use a flare wrench to avoid rounding off fittings when disconnecting brake lines.

7. Bleed the Brake System

After replacing any components, bleed the brake system to remove air.
Start at the wheel farthest from the master cylinder and move to the closest.
