Solution
1. Preparation
  • Gather necessary tools and parts.
  • Park the vehicle on a flat surface and engage the parking brake.
  • Disconnect the battery to ensure safety during repairs.
2. Check Brake Fluid and Lines
  • Open the hood and locate the brake master cylinder.
  • Use a clean rag to wipe the area around the master cylinder cap before removing it.
  • Check the brake fluid level; top off with the manufacturer-recommended brake fluid (usually DOT 3 or DOT 4).
  • Inspect the brake lines visually for leaks or damage. If leaks are found, replace the affected line.
3. Inspect and Replace Brake Booster
  • Locate the brake booster, which is typically mounted on the firewall.
  • Disconnect the vacuum line from the brake booster. Inspect the line for cracks or any signs of damage; replace if necessary.
  • Remove the mounting nuts or bolts (usually 4-6) securing the brake booster to the firewall.
  • Carefully pull the brake booster away from the firewall, and disconnect the pushrod from the brake pedal.
  • Install the new brake booster by reversing the removal steps, ensuring all connections are secure.
4. Bleed the Brake System
  • With the new brake booster installed, check the brake fluid level again and top off if necessary.
  • Bleed the brake system to remove any air that may have entered during the repair:
    • Start with the brake farthest from the master cylinder (usually the rear passenger side).
    • Have an assistant pump the brake pedal while you open the bleeder valve on the brake caliper, allowing fluid to flow until no air bubbles are present.
    • Repeat for the remaining brakes in the order of farthest to closest (rear passenger, rear driver, front passenger, front driver).
5. Final Checks
  • Reconnect the battery.
  • Test the brake pedal feel and check for any leaks around the brake booster and lines.
