Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a level surface and the engine is off.
  • Wear safety glasses and gloves.
2. Inspect and Replace Brake Fluid
  • Sub-steps:
    • Locate the master cylinder reservoir (usually near the back of the engine bay).
    • Remove the cap and check fluid level; fill with the recommended brake fluid (DOT 3 or DOT 4).
    • If fluid is contaminated (dark or cloudy), proceed to flush the brake system.
3. Inspect Brake Lines and Components
  • Sub-steps:
    • Visually inspect all brake lines for signs of corrosion, leaks, or damage.
    • Check brake calipers for fluid leaks and ensure they are functioning correctly.
    • If leaks are found, replace the damaged brake lines or calipers as needed.
4. Bleed the Brake System
  • Sub-steps:
    • Start at the brake furthest from the master cylinder (usually the right rear).
    • Attach a clear hose to the bleeder valve on the brake caliper and submerge the other end in a container with brake fluid.
    • Have an assistant pump the brake pedal several times, then hold it down.
    • Open the bleeder valve to release air and fluid, then close it before the pedal is released.
    • Repeat until no air bubbles are visible, then move to the next wheel.
    • Ensure to check fluid levels in the master cylinder throughout the process to prevent it from running dry.
5. Reassemble and Test
  • Sub-steps:
    • Replace any caps removed during the process.
    • Lower the vehicle if it was raised.
    • Start the engine and press the brake pedal to check for firmness.
    • Perform a test drive to ensure brakes are functioning correctly.
