Solution
1. Preparation
  • Gather tools and parts.
  • Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
  • Wear safety glasses and gloves.
2. Inspect and Replace Brake Booster

  1. Remove the Brake Booster:

    • Disconnect the negative battery terminal.
    • Remove the master cylinder by unbolting it from the brake booster.
    • Unbolt the brake booster from the firewall.
    • Disconnect the vacuum line from the brake booster.
    • Carefully remove the brake booster from the vehicle.

  2. Inspect and Clean:

    • Check for any visible damage to the brake booster and vacuum line.
    • Clean any debris from the mounting surfaces.

  3. Install New Brake Booster:

    • Position the new brake booster into place and secure it to the firewall.
    • Reconnect the vacuum line and ensure it is airtight.
    • Reattach the master cylinder to the brake booster, ensuring proper alignment and torque specifications (typically around 15-20 ft-lbs).
3. Brake Fluid Check and Replacement

  1. Inspect Brake Fluid:

    • Check the condition of the brake fluid in the master cylinder; if it appears contaminated, replace it.
    • Use DOT 3 or DOT 4 brake fluid as specified in the owner's manual.

  2. Bleed the Brake System:

    • Start at the furthest brake from the master cylinder (usually the passenger rear).
    • Attach a clear tube to the bleeder valve and submerge it in a container of brake fluid.
    • Have an assistant pump the brake pedal several times, then hold it down.
    • Open the bleeder valve to release air and fluid; close the valve before releasing the pedal.
    • Repeat until no air bubbles are present, then move to the next brake in order (driver rear, passenger front, driver front).
