Brake System, Bleeding
Brake System, Bleeding
• Description covers bleeding of brake system using the brake filler and bleeder tool (VAS 5234).
Only use new brake fluid conforming to VW standard (VW 501 14).
• Brake fluid must never come into contact with fluids containing mineral oils (oil, gas, cleaning solutions). Oils containing minerals damage seals and sleeves on brake systems.
• Brake fluid is poisonous. Due to its caustic nature, it must also never be brought into contact with paint.
• Brake fluid is hygroscopic, meaning that it absorbs moisture from the surrounding air, and must therefore be stored in air-tight containers.
• Wash off any spilled brake fluid with plenty of water.
• Do not reuse brake fluid once drained.
• Observe waste disposal regulations!
• There must be a positive pressure of 2 bar to bleed the hydraulic unit.
Install access cover for the brake bleeder.
