Solution
1. Preparation
  • Tools Required:
    • Brake fluid
    • OBD-II scanner
    • Vacuum gauge
  • Ensure the vehicle is parked on a level surface and the engine is off.
  • Wear safety goggles and gloves.
2. Inspect Brake Fluid
  • Open the hood and locate the master cylinder.
  • Check the brake fluid level; if low, top it off with the recommended brake fluid type (usually DOT 3 or DOT 4).
  • Inspect the fluid condition (should be clear, not dark or contaminated).
3. Inspect for Leaks
  • Visually examine all brake lines, hoses, and connections for signs of leaks.
  • If leaks are found, replace the affected lines or components as necessary.
4. Test Brake Booster
  • With the engine off, pump the brake pedal several times until it feels hard.
  • Start the engine while keeping pressure on the pedal; if the pedal sinks slightly, the booster is functioning correctly. If not, the booster may be defective.
5. Replace Brake Booster (if necessary)
  • Disconnect the negative battery terminal.
  • Remove any components obstructing access to the brake booster.
  • Disconnect the brake lines from the master cylinder, and unbolt the master cylinder from the booster if necessary.
  • Unbolt the brake booster from the firewall, and remove it from the vehicle.
  • Install the new brake booster, reversing the removal steps, ensuring all bolts are torqued to specifications (check service manual for specifics).
