Solution
1. Preparation
  • Gather necessary tools and parts.
  • Park the vehicle on a level surface and engage the parking brake.
  • Disconnect the negative battery terminal to ensure safety.
2. Inspect Brake Fluid Level
  • Remove the master cylinder cap and check the brake fluid level.
  • If low, top off with the recommended brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).
  • Reinstall the cap securely.
3. Check and Replace Brake Booster Hose
  • Locate the brake booster hose connected to the intake manifold.
  • Inspect for cracks or leaks. If damaged, replace the hose using a socket set.
  • Ensure a secure fit to prevent vacuum loss.
4. Test Brake Booster Function
  • With the engine off, pump the brake pedal several times to deplete the vacuum.
  • Start the engine; the brake pedal should drop slightly due to the booster assisting.
  • If there is no change, the brake booster may need replacement.
5. Replace Brake Booster (if necessary)
  • Remove the brake booster by unbolting it from the firewall (typically 4-5 bolts).
  • Disconnect the master cylinder from the brake booster (may require removal of the master cylinder).
  • Install the new brake booster by reversing the removal steps, ensuring all bolts are torqued to specifications (typically 15-20 ft-lbs).
