Solution
1. Preparation
  • Gather all necessary tools and parts.
  • Ensure the vehicle is parked on a level surface with the engine off.
  • Disconnect the negative battery terminal to prevent electrical shorts.
2. Inspect and Replace the Brake Booster

  • Inspect the Brake Booster:

    • Remove the engine cover if necessary.
    • Visually inspect the brake booster for any signs of damage, cracks, or leaks.

  • Replace the Brake Booster:

    1. Disconnect the vacuum line from the brake booster.
    2. Remove the retaining nuts/bolts securing the brake booster to the firewall.
    3. Detach the brake master cylinder from the brake booster (may need to remove brake lines; ensure to have a catch pan for any fluid).
    4. Remove the old brake booster from the vehicle.
    5. Install the new brake booster by reversing the removal steps; ensure proper sealing of the vacuum line.
    6. Reattach the brake master cylinder and secure it with the appropriate torque specifications.
3. Refill and Bleed the Brake System
  • Refill the master cylinder with the recommended brake fluid type (DOT 3 or DOT 4).
  • Bleed the brake system to eliminate any air bubbles:
    1. Start with the wheel farthest from the master cylinder (usually the right rear).
    2. Open the bleeder valve while an assistant presses the brake pedal.
    3. Close the valve before the pedal is released.
    4. Repeat until no bubbles emerge; move to the next wheel in proper order.
4. Final Checks
  • Reconnect the negative battery terminal.
  • Start the engine and check for any abnormal noises.
  • Test the brakes by applying pressure to ensure they feel normal.
