Solution
1. Preparation
  • Gather tools and parts needed for the repair.
  • Ensure the vehicle is parked on a level surface and engage the parking brake.
  • Disconnect the negative battery terminal to prevent electrical shorts.
2. Brake Fluid Inspection and Replacement
  • Remove the brake fluid reservoir cap.
  • Use a turkey baster or siphon to extract old brake fluid from the reservoir.
  • Replace with manufacturer-recommended brake fluid (e.g., VW DOT 4).
  • Reinstall the reservoir cap securely.
3. Brake Line and Hose Inspection
  • Visually inspect all brake lines and hoses for signs of wear, corrosion, or leaks.
  • If leaks are found, replace the damaged line or hose using a brake line wrench.
  • Bleed the brake system to remove air as detailed in the next step.
4. Bleeding the Brake System
  • Start with the brake furthest from the master cylinder (usually the passenger rear).
  • Attach a clear tube to the bleeder valve and place the other end in a container.
  • 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.
  • Repeat until no air bubbles appear, then move to the next wheel in the correct order (passenger rear, driver rear, passenger front, driver front).
  • Maintain fluid level in the reservoir during the process to avoid introducing air.
5. Final Inspection and Reassembly
  • Inspect all connections for leaks after bleeding.
  • Recheck the brake fluid level in the reservoir and add more if necessary.
  • Reconnect the negative battery terminal.
  • Replace any components removed during the inspection.
