Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is on a level surface and secure it with wheel chocks.
  • Wear safety gloves and goggles for protection.
2. Inspect and Refill Brake Fluid
  • Sub-steps:
    1. Open the hood and locate the brake fluid reservoir.
    2. Remove the cap and check the fluid level; add the recommended brake fluid (DOT 3 or DOT 4) if low.
    3. Inspect the reservoir for cracks or damage.
3. Bleed the Brake System
  • Sub-steps:
    1. Locate the brake bleeder valves on each wheel.
    2. Attach a clear hose to the bleeder valve and place the other end in a container.
    3. Have an assistant pump the brake pedal several times and hold it down.
    4. Open the bleeder valve to release air and fluid; close the valve before the assistant releases the pedal.
    5. Repeat until all air bubbles are removed, and brake fluid runs clear.
    6. Ensure the brake fluid reservoir remains full throughout the process.
4. Inspect and Replace Brake Components (if necessary)
  • Sub-steps:
    1. Remove the wheel to access the brake assembly.
    2. Inspect brake pads for wear; replace if the thickness is below the manufacturer’s specification.
    3. Check the rotors for scoring or warping; replace if damaged.
    4. Inspect the brake lines for any signs of wear or corrosion; replace as needed.
5. Check Brake Booster and Vacuum Lines
  • Sub-steps:
    1. Inspect the brake booster for any signs of damage or leaks.
    2. Check the vacuum hose connected to the brake booster for cracks or disconnections.
    3. Replace any faulty components as necessary.
