Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a flat surface and the wheels are chocked.
  • Wear safety gloves and goggles.
2. Check and Refill Brake Fluid
  • Sub-steps:
    • Open the hood and locate the brake master cylinder.
    • Remove the cap and check the brake fluid level.
    • If low, add the appropriate brake fluid (DOT 4) to the correct level.
    • Replace the cap securely.
3. Inspect and Repair Brake Leaks
  • Sub-steps:
    • Visually inspect all brake lines, hoses, and connections for leaks.
    • If leaks are found, replace the affected brake line or hose.
    • Tighten any loose fittings to eliminate minor leaks.
4. Bleed the Brake System
  • Sub-steps:
    • Attach a brake bleeder kit to the brake bleeder valve on each wheel caliper, starting from the farthest caliper from the master cylinder (usually rear right).
    • Have an assistant pump the brake pedal several times and hold it down.
    • Open the bleeder valve to release air and fluid, then close it before the assistant releases the pedal.
    • Repeat until no air bubbles are observed in the fluid.
    • Move to the next caliper and repeat the procedure until all calipers are bled.
5. Check Brake Booster Functionality
  • Sub-steps:
    • Inspect the brake booster for any cracks or damage.
    • With the engine off, pump the brake pedal several times to deplete vacuum.
    • Hold the pedal down and start the engine; the pedal should drop slightly if the booster is functioning properly. If not, replace the brake booster.
