Solution
1. Preparation
  • Gather tools: socket set, wrench set, brake fluid, brake cleaner, and a jack with jack stands.
  • Ensure the vehicle is on a flat surface and engage the parking brake.
  • Wear safety gloves and goggles.
2. Inspect and Replace Brake Fluid
  • Sub-steps:
    1. Open the hood and locate the brake master cylinder.
    2. Remove the cap and inspect the brake fluid level.
    3. If low, add the appropriate brake fluid (check owner’s manual for specifications).
    4. If fluid is contaminated or low due to leaks, proceed to replace fluid.
3. Check for Leaks and Repair
  • Sub-steps:
    1. Visually inspect all brake lines, hoses, and connections for signs of leaks.
    2. Tighten any loose connections or replace damaged lines.
    3. If leaking from the master cylinder, remove it by unbolting it from the brake booster and disconnecting the brake lines.
    4. Replace the master cylinder with a new one, ensuring to use new seals and bolts as needed.
4. Bleed the Brake System
  • Sub-steps:
    1. Fill the master cylinder with new brake fluid.
    2. Start bleeding the brakes at the farthest wheel from the master cylinder (usually the passenger rear), using a helper to pump the brake pedal.
    3. Open the bleed valve until fluid flows out, then close it before the pedal hits the floor.
    4. Repeat for all brakes in the proper order (passenger rear, driver rear, passenger front, driver front).
    5. Ensure no air bubbles are present when bleeding.
