Solution
1. Preparation
  • Gather tools: socket set, OBD-II scanner, vacuum gauge, and safety goggles.
  • Ensure the vehicle is parked on a level surface and the ignition is off.
2. Check Brake Fluid
  • Locate the master cylinder reservoir under the hood.
  • Remove the cap and check the brake fluid level.
    • If low, top off with the manufacturer's recommended brake fluid (DOT 3 or DOT 4).
3. Inspect the Brake Booster
  • Visually inspect the brake booster for any physical damage or signs of fluid leakage.
  • If damaged, proceed to replace the brake booster.
    • Tools Needed: socket set, torque wrench.
    • Safety Warning: Disconnect the battery before starting work.
4. Test Brake Booster Operation
  • With the engine off, pump the brake pedal multiple times to exhaust any vacuum.
  • Start the engine while pressing the brake pedal; it should depress slightly.
    • If it remains hard, the brake booster may be defective.
5. Inspect Vacuum Lines
  • Trace the vacuum lines from the engine to the brake booster.
  • Look for any cracks, disconnections, or blockages.
    • If damaged, replace the affected vacuum line.
6. Replace Brake Booster (if needed)
  • Disconnect the brake lines from the master cylinder and remove the master cylinder.
  • Unbolt the brake booster from the firewall.
  • Install the new brake booster, ensuring all bolts are torqued to the manufacturer’s specifications.
  • Reattach the master cylinder and brake lines.
