Solution
1. Preparation
  • Tools Required: Socket set, brake fluid, OBD-II scanner, brake bleeder kit.
  • Ensure the vehicle is on a flat surface, and use wheel chocks to prevent rolling.
2. Inspect and Refill Brake Fluid
  • Sub-steps:
    1. Locate the brake fluid reservoir, usually found near the back of the engine bay.
    2. Check the fluid level against the "Min" and "Max" markings.
    3. If low, add the appropriate brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).
3. Check for Leaks
  • Sub-steps:
    1. Inspect all brake lines and hoses for any visible signs of leaks or wear.
    2. Examine the brake calipers for fluid leaks.
    3. If any leaks are found, replace the damaged components.
4. Replace Brake Pads and Rotors (if necessary)
  • Sub-steps:
    1. Remove the wheel to access the brake assembly.
    2. Unbolt the caliper and remove it, ensuring to support it hanging to avoid strain on the brake line.
    3. Remove the old brake pads and inspect the rotors for warping or scoring; replace if damaged.
    4. Install new brake pads and reassemble the caliper, torquing bolts to manufacturer specifications.
5. Bleed the Brake System
  • Sub-steps:
    1. Attach the brake bleeder kit to the brake bleeder valve on the caliper.
    2. Have an assistant press the brake pedal while you open the valve to release air and fluid.
    3. Close the valve before the pedal is released to prevent air from entering.
    4. Repeat until no air bubbles appear in the fluid.
    5. Repeat the process for each wheel, following the specific order recommended in the service manual.
