Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a level surface and engage the parking brake.
  • Disconnect the negative battery terminal.
2. Check Brake Fluid
  • Open the hood and locate the brake master cylinder.
  • Remove the cap and check the fluid level.
  • If low, top off with manufacturer-recommended brake fluid (DOT 3 or DOT 4 as specified).
3. Inspect Brake Booster
  • Locate the brake booster (it is mounted on the firewall).
  • Inspect for any physical damage or corrosion.
  • If the booster is faulty, remove it:
    • Disconnect the vacuum line from the booster.
    • Unbolt the booster from the firewall using a socket set.
    • Remove the pushrod from the brake pedal.
4. Replace Brake Booster (if necessary)
  • Install the new brake booster:
    • Attach the pushrod to the brake pedal.
    • Bolt the new booster to the firewall with proper torque specifications (generally around 15-20 ft-lbs).
    • Reconnect the vacuum line ensuring a tight fit.
5. Test the Brake System
  • Refill the brake fluid reservoir if necessary.
  • Reconnect the negative battery terminal.
  • Start the engine and press the brake pedal to verify normal operation.
  • Check for any leaks around the brake components.
