  • Ensure the vehicle is parked on a flat surface, and the ignition is turned off.
  • Wear safety gloves and goggles.
2. Inspect and Replace Brake Booster

  1. Remove the Engine Cover (if necessary):

    • Use a socket set to unbolt any fasteners.
    • Carefully lift off the engine cover.

    • Carefully disconnect it, checking for damage or cracks.

  3. Remove the Brake Booster:

    • Unbolt the brake booster from the firewall using the socket set.
    • Disconnect the pushrod from the brake pedal by removing the retaining clip.
    • Carefully pull the brake booster out of the engine compartment.

  4. Inspect the Brake Booster:

    • Check for any internal damage or signs of failure.
    • If the brake booster is faulty, replace it with a new one.

  5. Install the New Brake Booster:

    • Position the new brake booster into place and reconnect the pushrod to the brake pedal.
    • Bolt the booster back onto the firewall using the socket set.
