Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is on a flat surface and secure it with wheel chocks.
  • Wear safety goggles and gloves for protection.
2. Inspect and Repair Brake Lines
  • Sub-steps:
    1. If any leaks are found in the brake lines or hoses, replace the damaged section with new brake line or hose.
    2. Use a flare wrench to disconnect the brake line from the fitting.
    3. Install the new line or hose, ensuring all connections are tight.
    4. Bleed the braking system to remove air from the lines.
3. Replace Master Cylinder (if necessary)
  • Tools Required: Socket set, brake line wrench, torque wrench, container for brake fluid.
  • Sub-steps:
    1. Disconnect the battery to prevent electrical issues.
    2. Remove the brake fluid from the master cylinder reservoir using a siphon.
    3. Disconnect the brake lines from the master cylinder using a brake line wrench.
    4. Unbolt the master cylinder from the brake booster.
    5. Install the new master cylinder, tightening bolts to manufacturer specifications (typically around 15-20 ft-lbs).
    6. Reconnect the brake lines and refill the master cylinder with new brake fluid.
4. Bleed the Brake System
  • Sub-steps:
    1. Start at the brake furthest from the master cylinder (usually the rear passenger side).
    2. Connect a clear hose to the bleeder valve and place the other end in a container.
    3. Have an assistant press the brake pedal while you open the bleeder valve to release air and fluid.
    4. Close the valve and repeat until no air bubbles are present.
    5. Repeat this process for each wheel in the order: rear passenger, rear driver, front passenger, and front driver.
