Solution

Solution

1. Preparation

  • Tools Required: Brake fluid, socket set, vacuum gauge, OBD-II scanner, brake cleaner, rags.
  • Ensure the vehicle is parked on a level surface and the engine is off.
  • Disconnect the negative terminal of the battery for safety.

2. Brake Fluid Inspection

  • Open the hood and locate the brake master cylinder reservoir.
  • Check the brake fluid level; if low, top it off with the manufacturer-recommended brake fluid.
  • Inspect for any signs of contamination or discoloration in the fluid. If contaminated, the fluid will need to be flushed.

3. Brake Booster Inspection

  • Locate the brake booster (usually mounted on the firewall).
  • Detach the vacuum hose connected to the brake booster.
  • Use a vacuum gauge to test the vacuum at the brake booster port. A reading below 18 inHg indicates a vacuum issue.
  • If the vacuum is low, inspect the vacuum hose for leaks or blockages.

4. Brake Pedal Assembly Inspection

  • Remove the lower dash panel to access the brake pedal assembly.
  • Inspect the pivot points and bushings for wear or damage.
  • Apply lubricant to any moving parts that may be binding.

5. Brake System Functionality Check

  • Reconnect the vacuum hose and the battery terminal.
  • Test the brake pedal; it should feel firm yet responsive.
  • If issues persist, consider replacing the brake booster or further inspecting the master cylinder.

Verification

After completing the repair, verify that the issue has been resolved:

  • Test the affected component to ensure it functions correctly
  • Check for any error codes or warning lights
