Solution
1. Preparation
  • Gather tools and necessary parts.
  • Ensure the vehicle is parked on a level surface and the parking brake is engaged.
  • Wear safety glasses and gloves for protection.
2. Check and Replenish Brake Fluid
  • Sub-steps:
    1. Open the hood and locate the brake master cylinder reservoir.
    2. Inspect the fluid level; if low, add the appropriate type of brake fluid (DOT 3 or DOT 4 as specified).
    3. Close the reservoir cap securely.
3. Inspect and Repair Leaks
  • Sub-steps:
    1. Visually inspect all brake lines and hoses for signs of fluid leaks or damage.
    2. If leaks are found, replace the damaged brake line or hose.
    3. Tighten any loose connections or fittings.
4. Bleed the Brake System
  • Sub-steps:
    1. Start at the wheel farthest from the master cylinder (usually the right rear).
    2. Attach a clear plastic tube to the bleeder valve on the brake caliper.
    3. Have an assistant pump the brake pedal several times and hold it down.
    4. Open the bleeder valve to release air and brake fluid, then close it before the pedal is released.
    5. Repeat this process until no air bubbles are seen in the tube.
    6. Move to the next wheel and repeat until all brakes are bled.
5. Replace the Brake Master Cylinder (if necessary)
  • Sub-steps:
    1. Disconnect the brake lines from the master cylinder using a line wrench to avoid damage.
    2. Remove the mounting bolts securing the master cylinder to the brake booster.
    3. Install the new master cylinder, ensuring all connections are tight.
    4. Reconnect the brake lines and bleed the brake system as outlined above.
