Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a level surface with the engine off and the parking brake engaged.
  • Wear safety glasses and gloves.
2. Check and Replace Brake Fluid
  • Open the master cylinder reservoir cap:
    • Use a clean cloth to wipe around the cap before opening.
  • Inspect the brake fluid:
    • If low, top off with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
  • If the fluid is contaminated, drain and replace all brake fluid:
    • Use a brake bleeder kit to flush the system if necessary.
3. Inspect and Replace Brake Booster
  • Remove the vacuum line from the brake booster:
    • Use pliers to loosen any clamps if necessary.
  • Check for cracks or obstructions in the vacuum line.
  • Remove the brake booster:
    • Disconnect the master cylinder from the booster.
    • Unbolt the brake booster from the firewall (typically 4 bolts).
  • Install the new brake booster:
    • Follow the reverse order of removal.
    • Torque the bolts to the manufacturer's specifications (usually 15-20 ft-lbs).
4. Check Master Cylinder Functionality
  • Inspect the master cylinder for signs of wear or leakage:
    • If damaged, replace the master cylinder.
  • Reattach the brake lines to the master cylinder and torque to specifications.
5. Final Checks
  • Reconnect the vacuum line to the brake booster.
  • Start the vehicle and check for any abnormal noises or leaks.
  • Test the brake pedal feel by pressing it several times to ensure it feels normal.
