Solution
1. Preparation
  • Gather necessary tools and parts.
  • Safely elevate the vehicle on jack stands to access the undercarriage.
  • Ensure the engine is off and the parking brake is engaged.
2. Inspect and Refill Brake Fluid
  • Check the brake fluid reservoir.
    • If low, refill with DOT 3 or DOT 4 brake fluid as specified in the owner’s manual.
  • Inspect brake fluid for contamination (e.g., discoloration, particles).
3. Check for Leaks
  • Inspect all brake lines for signs of fluid leakage.
    • If leaks are found, replace the damaged line or fitting.
  • Inspect the brake calipers for leaks around the seals and replace if necessary.
4. Brake Component Inspection
  • Remove the wheel to inspect the brake pads and rotors.
    • Replace pads if they are worn beyond the manufacturer’s specifications (typically 3mm or less of pad material).
    • Ensure rotors are not warped or excessively worn; replace if necessary.
5. Brake Booster Test
  • With the engine off, pump the brake pedal several times to deplete the vacuum.
  • Start the engine and observe pedal response.
    • If the pedal drops significantly, the brake booster may be faulty and needs replacement.
6. Bleed Brake System
  • If air is suspected in the brake lines, perform a brake system bleed.
    • Start with the wheel farthest from the master cylinder (typically the right rear).
    • Use a brake bleeder kit or have an assistant pump the brake pedal while you open and close the bleeder valve on each caliper.
    • Ensure to top off brake fluid throughout the process.
