Solution
1. Preparation
  • Gather necessary tools and parts.
  • Park the vehicle on a level surface and engage the parking brake.
  • Wear safety glasses and gloves.
2. Inspect and Replace Brake Fluid
  • If the brake fluid is low, top it off with the recommended brake fluid type (DOT 3 or DOT 4 as specified in the owner's manual).
  • If the fluid is dirty or contaminated, proceed to flush the brake system.
3. Check and Repair Brake Lines
  • Use a wrench to carefully disconnect the brake lines from the master cylinder and calipers if leaks are found.
  • Inspect all brake lines for rust or damage; replace any compromised lines.
  • Reconnect the brake lines and ensure they are properly tightened to manufacturer specifications.
4. Inspect and Replace Master Cylinder (if necessary)
  • If the master cylinder is leaking, remove it by unscrewing the mounting bolts.
  • Disconnect the brake lines and electrical connectors.
  • Install the new master cylinder by reversing the removal steps, ensuring all connections are tight and leak-free.
5. Bleed the Brake System
  • Start by filling the master cylinder with fresh brake fluid.
  • Bleed the brakes using the two-person method or a one-person bleeder kit:
    1. Have an assistant pump the brake pedal several times and hold it down.
    2. Open the bleeder valve on the farthest brake caliper from the master cylinder, allowing fluid to escape until there are no air bubbles.
    3. Close the bleeder valve, and have the assistant release the brake pedal.
    4. Repeat for each brake caliper in sequence (farthest to closest).
