Solution
1. Preparation
  • Gather tools and parts: OBD-II scanner, vacuum gauge, socket set, brake fluid.
  • Ensure the vehicle is on a level surface and secure it with wheel chocks.
  • Disconnect the negative battery terminal to prevent any electrical issues.
2. Inspect the Brake Booster
  • Remove the engine cover if applicable for better access.
  • Visually inspect the brake booster for any signs of cracks, corrosion, or fluid leaks.
  • Check the mounting points for security and integrity.
3. Check the Vacuum Supply
  • Locate the vacuum line connected to the brake booster.
  • Inspect the line for any signs of wear, cracks, or disconnections.
  • Replace any damaged vacuum lines with new ones.
4. Test the Brake Booster
  • Connect a vacuum gauge to the brake booster vacuum port.
  • Start the engine and allow it to idle, then observe the gauge.
  • Ensure that the vacuum reading is within the manufacturer’s specifications (typically around 18-22 inHg).
  • If vacuum is low, check for leaks in the intake manifold or replace the brake booster if necessary.
5. Inspect and Refill Brake Fluid
  • Remove the cap from the master cylinder reservoir and check the fluid level.
  • If low, top off with the manufacturer-recommended brake fluid type.
  • Inspect the fluid for contamination or discoloration; replace if necessary.
6. Reassemble and Test
  • Reconnect any components that were removed during inspection.
  • Reconnect the negative battery terminal.
  • Start the vehicle and press the brake pedal several times to ensure it feels normal.
