Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is on a flat surface and securely supported with jack stands.
  • Wear safety glasses and gloves for protection.
2. Check and Refill Brake Fluid
  • Locate the brake fluid reservoir (usually near the driver's side).
  • Remove the cap and check fluid level; if low, refill with the appropriate brake fluid (usually DOT 4 for VW).
  • Inspect for leaks around the reservoir seal.
3. Inspect and Repair Brake Lines
  • Visually inspect all brake lines for signs of wear or damage.
  • If leaks are found in the brake lines, use a line wrench to disconnect the damaged section.
  • Cut and replace the damaged section of the brake line with new brake line tubing.
  • Use a flaring tool to create proper fittings on the new line and secure it in place.
4. Replace or Repair Master Cylinder
  • If the master cylinder is leaking, remove the brake lines connected to it (using a line wrench).
  • Unbolt the master cylinder from the brake booster (typically 2-4 bolts).
  • Replace with a new master cylinder or rebuild it if applicable.
  • Reinstall the new or rebuilt master cylinder and reconnect brake lines.
5. Bleed the Brake System
  • Fill the brake fluid reservoir to the proper level.
  • Begin bleeding the brakes at the furthest wheel from the master cylinder (usually the passenger rear).
  • Use a brake bleeder kit or have an assistant pump the brake pedal while you open the bleeder valve to expel air and old fluid.
  • Repeat this process for each wheel (passenger rear, driver rear, passenger front, driver front) until no air bubbles are present and fluid runs clear.
6. Test the Brake System
  • Once bleeding is complete, check the brake pedal feel.
  • Start the engine and test the brakes at low speed to ensure proper function.
  • Inspect for leaks during the test.
