Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Wear safety glasses and gloves.

2. Check and Refill Brake Fluid

Locate the master cylinder reservoir under the hood.
Inspect the fluid level; it should be between the "MAX" and "MIN" lines.
If low, top off with the manufacturer's recommended brake fluid (typically DOT 3 or DOT 4).

3. Inspect Brake Lines and Components

Visually inspect brake lines for any signs of leaks or corrosion.
If leaks are found, replace the damaged sections of the brake line.
Inspect brake calipers for leaks; replace if necessary.

4. Bleed Brake System

Start with the brake furthest from the master cylinder (usually the passenger rear).
Attach a clear hose to the bleeder valve and place the other end in a container.
Have an assistant pump the brake pedal several times, then hold it down.
Open the bleeder valve to allow air and fluid to escape until the pedal feels firm, then close the valve.
Repeat for each wheel in the correct order (passenger rear, driver rear, passenger front, driver front).

5. Test Brake Booster

With the engine off, pump the brake pedal several times until it becomes hard.
Keep the pedal pressed down, then start the engine. The pedal should drop slightly, indicating the booster is functioning properly.
If not, replace the brake booster.
