Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Engage the parking brake for safety.

2. Check Brake Fluid

Sub-steps:
- Locate the brake fluid reservoir; it is typically near the driver's side of the engine bay.
- Clean the area around the reservoir cap to prevent contamination.
- Remove the cap and check the fluid level against the "MIN" and "MAX" marks.
- If low, top up with the recommended brake fluid type (usually DOT 3 or DOT 4).

3. Inspect Brake Components

Sub-steps:
- Remove the wheel to access the brake assembly.
- Inspect brake pads for thickness; replace if below 3mm.
- Check rotors for scoring, warping, or excessive wear.
- Replace any worn or damaged components.

4. Examine Brake Lines and Hoses

Sub-steps:
- Inspect all brake lines for signs of leaks or damage.
- Tighten any loose connections.
- Replace any damaged lines or hoses with OEM parts.

5. Test Brake Booster

Sub-steps:
- With the engine off, press the brake pedal several times to deplete vacuum.
- Start the engine while pressing the brake pedal; it should feel softer after starting.
- If there is no change, the brake booster may need replacement.
