Solution
1. Preparation
  • Gather tools and materials: Brake fluid, socket set, brake line wrench, OBD-II scanner, and vacuum pump (if needed).
  • Ensure the vehicle is parked on a level surface and the engine is off.
  • Wear safety gloves and goggles.
2. Check and Refill Brake Fluid
  • Locate the master cylinder reservoir.
  • Remove the cap and check the fluid level. If low, add the appropriate type of brake fluid (DOT 3 or DOT 4).
  • Replace the cap securely.
3. Inspect for Leaks
  • Visually inspect brake lines for any cracks or signs of wear.
  • Check around the brake calipers and master cylinder for fluid leaks.
  • If leaks are found, replace the damaged lines or components as necessary.
4. Bleed the Brake System
  • If the fluid level was low or if air is suspected in the brake lines, bleeding may be necessary.
  • Use a brake bleeder kit:
    1. Connect the kit to the brake caliper.
    2. Have an assistant pump the brake pedal several times and hold it down.
    3. Open the bleeder valve to allow fluid and air to escape.
    4. Close the valve and have the assistant release the pedal.
    5. Repeat until no air bubbles are visible in the outgoing fluid.
  • Repeat for each wheel, starting with the wheel farthest from the master cylinder.
5. Replace Brake Pads and Rotors (if necessary)
  • If pads or rotors are worn, follow these sub-steps:
    1. Loosen the lug nuts on the wheel.
    2. Lift the vehicle and secure it on jack stands.
    3. Remove the wheel.
    4. Remove the caliper and hang it securely (do not let it dangle).
    5. Replace the brake pads and, if necessary, the rotors.
    6. Reassemble by reversing the steps and torque lug nuts to manufacturer specifications.
