Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is on a flat surface and securely lifted using jack stands.
  • Wear safety goggles and gloves.
2. Inspect and Refill Brake Fluid
  • Sub-steps:
    1. Open the hood and locate the master cylinder.
    2. Remove the cap and visually inspect the brake fluid level.
    3. If low, refill with the recommended brake fluid type (DOT 3 or DOT 4).
    4. Replace the cap securely.
3. Bleed the Brake System
  • Sub-steps:
    1. Starting from the wheel farthest from the master cylinder (usually rear passenger), attach a clear hose to the bleeder valve on the brake caliper.
    2. Place the other end of the hose in a container to catch fluid.
    3. Have an assistant pump the brake pedal several times and hold it down.
    4. Open the bleeder valve to release air and fluid, then close the valve before the assistant releases the brake pedal.
    5. Repeat until no air bubbles appear in the fluid.
    6. Move to the next wheel and repeat the process (rear driver, front passenger, front driver).
4. Inspect and Replace Components
  • Sub-steps:
    1. Inspect brake lines for corrosion or damage. Replace if necessary.
    2. Check the condition of the brake calipers; replace if leaking or damaged.
    3. Examine the master cylinder for leaks and replace if faulty.
    4. Inspect the brake booster for proper operation.
5. Final Assembly and Test
  • Sub-steps:
    1. Recheck all connections and ensure that all bleeder screws are tightened.
    2. Lower the vehicle from jack stands.
    3. Test drive the vehicle at low speeds to check brake function.
    4. Ensure the brake pedal feels firm and responsive.
