Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a level surface and the engine is off.
  • Wear safety goggles and gloves.
2. Brake Fluid Inspection
  • Remove the master cylinder reservoir cap.
  • Check the brake fluid level; if it's low, top it off with the manufacturer-recommended fluid.
  • Inspect for any signs of contamination in the fluid.
3. Brake Booster Testing
  • Disconnect the vacuum hose from the brake booster.
  • Using a vacuum pump, apply vacuum to the brake booster. Ensure that it holds vacuum without leaking.
  • If it does not hold vacuum, replace the brake booster.
4. Brake Line Inspection
  • Visually inspect brake lines for any leaks or corrosion.
  • If any leaks are found, replace the affected lines and bleed the brake system to remove air.
5. Reassemble and Test
  • Reconnect the vacuum hose to the brake booster.
  • Refill the brake fluid if necessary and replace the master cylinder reservoir cap.
  • Test the brake pedal feel by pressing it several times and ensure it operates smoothly.
