Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and securely supported with jack stands.
Disconnect the negative battery terminal to prevent electrical issues.

2. Identify and Repair Leak

Inspect Brake Lines and Hoses
- Use a flashlight to inspect brake lines for fluid stains.
- If a leak is found, replace the affected brake line or hose with a new part.
- Tools Required: Wrench set, brake line cutter, flare nut wrench.
Examine the Master Cylinder
- Remove the master cylinder reservoir cap.
- Check for fluid leakage around the master cylinder base.
- If leaking, replace the master cylinder.
- Tools Required: Wrench set, brake fluid.

3. Replace Brake Fluid

Drain any old brake fluid from the system using a brake bleeder tool.
Refill the brake fluid reservoir with the manufacturer's recommended brake fluid type (DOT 3 or DOT 4).
Tools Required: Brake bleeder tool, funnel.

4. Bleed Brake System

Start from the furthest brake from the master cylinder (usually the right rear).
Open the bleeder valve and have an assistant pump the brake pedal until no more air bubbles appear.
Close the valve and repeat for all four brakes.
Tools Required: Bleeder wrench, clear tubing.

5. Final Checks

Recheck all connections and ensure they are secure.
Reconnect the battery terminal.
