Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is on a level surface and secure it with wheel chocks.
  • Disconnect the negative battery terminal for safety.
2. Inspect Brake Fluid
  • Remove the master cylinder cap.
  • Check the brake fluid level; if low, top it up with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
  • Inspect for any contamination in the fluid.
3. Check Brake Booster and Vacuum Supply
  • Locate the brake booster vacuum hose and ensure it is securely connected to the intake manifold.
  • Use a vacuum gauge to check for proper vacuum (should be between 18-22 inHg at idle).
  • If vacuum is low, inspect the hose for leaks or kinks.
4. Test and Replace Brake Booster (if needed)
  • If the brake booster fails the vacuum test, disconnect the brake booster vacuum hose and remove the mounting bolts securing the brake booster to the firewall.
  • Carefully remove the brake booster and disconnect the pushrod from the brake pedal.
  • Install the new brake booster by reversing the removal process, ensuring all connections are tight.
  • Torque the mounting bolts to the manufacturer's specifications.
5. Final Checks
  • Refill the brake fluid reservoir if necessary.
  • Reconnect the negative battery terminal.
  • Pump the brake pedal several times to ensure proper function.
