Solution
1. Preparation
  • Tools Required: Socket set, screwdrivers, vacuum gauge, OBD-II scanner.
  • Ensure the vehicle is parked on a flat surface and the engine is off.
  • Disconnect the negative battery terminal to avoid electrical issues.
2. Check Brake Fluid Level
  • Locate the master cylinder reservoir.
  • Remove the cap and check the fluid level; if low, top off with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
  • Reinstall the cap securely.
3. Inspect Brake Booster
  • Visually inspect the brake booster for any signs of cracks or leaks.
  • Disconnect the vacuum line from the brake booster and check for any obstructions.
  • If necessary, replace the vacuum line if damaged.
4. Test Brake Booster Functionality
  • Press the brake pedal several times with the engine off to deplete any vacuum.
  • Start the engine while pressing the brake pedal; if the pedal sinks slightly, the booster is functioning correctly. If not, replace the brake booster.
5. Reassemble and Reconnect
  • If components were removed, reinstall them in the reverse order of disassembly.
  • Reconnect the negative battery terminal.
  • Ensure all tools are removed from the vehicle.
