Solution

1. Preparation

Gather tools: Brake fluid, brake line wrench, socket set, vacuum bleeder, and safety goggles.
Ensure the vehicle is parked on a level surface and the ignition is off.
Wear safety goggles to protect your eyes from brake fluid and contaminants.

2. Check and Refill Brake Fluid

Locate the master cylinder reservoir under the hood.
Inspect the brake fluid level. If low, add the appropriate type of brake fluid (DOT 3 or DOT 4 as specified in the owner’s manual).
Securely close the reservoir cap.

3. Inspect Brake Lines and Components

Visually inspect all brake lines for cracks or leaks, especially at connection points.
If leaks are found, replace the damaged brake line or fittings as necessary.

4. Bleed the Brake System

If the brake fluid is at the correct level and there are no leaks, proceed to bleed the brake system to remove any air bubbles.
Use a vacuum bleeder or perform manual bleeding:
- Start with the wheel farthest from the master cylinder (usually the rear passenger side).
- Attach a hose to the bleeder valve on the brake caliper and place the other end in a container.
- Open the valve and have an assistant press the brake pedal several times, then hold it down while you close the valve.
- Repeat until clear fluid without bubbles flows out, then move to the next wheel (rear driver side, front passenger side, and finally front driver side).

5. Test Brake System Functionality

After bleeding, check the brake pedal firmness by pressing it down. It should feel firmer.
Conduct a test drive in a safe, controlled environment to assess brake response and effectiveness.
