Solution
1. Preparation
  • Gather necessary tools and parts.
  • Park the vehicle on a flat surface and set the parking brake.
  • Wear safety gloves and goggles.
2. Inspect Brake Fluid Level
  • Open the hood and locate the brake fluid reservoir.
  • Check the fluid level; if low, top it up with the recommended brake fluid (DOT 4 or as specified in the owner’s manual).
3. Check for Brake Fluid Leaks
  • Visually inspect brake lines, connections, and the master cylinder for signs of leakage.
  • If leaks are found, replace damaged hoses or seals as necessary.
4. Test the Brake Booster Functionality
  • With the engine off, pump the brake pedal several times to deplete any vacuum.
  • Start the engine while pressing the brake pedal; the pedal should sink slightly, indicating proper booster operation. If it does not, the booster may need replacement.
5. Inspect Vacuum Hose
  • Trace the vacuum hose from the engine to the brake booster.
  • Check for any cracks or disconnections; replace the hose if damaged.
6. Replace Brake Booster (if necessary)
  • Disconnect the negative battery terminal.
  • Remove the vacuum hose from the brake booster.
  • Detach the master cylinder from the brake booster (may require unbolting).
  • Unbolt the brake booster from its mounting points.
  • Install the new brake booster by reversing the removal steps and ensuring all connections are secure.
