Brake System, Bleeding

Brake System, Bleeding

Description covers bleeding of brake system using the brake filler/bleeder unit (VAS 5234).


Only use new brake fluid conforming to VW standard (VW 501 14).


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.

• Rinse off any spilled brake fluid using plenty of water.

• There must be a positive pressure of 2 bar to bleed the hydraulic unit.
