Bleeding braking system Audi A8 D3 facelift

Bleeding braking system

CAUTIONDo not, under any circumstances, allow brake fluid to come into contact with any fluids containing mineral oil (oil, gasoline, cleaning solvents). Mineral oil damages the sealing plugs and boots of the brake system. Brake fluid is poisonous. NEVER siphon brake fluid with your mouth! Also due to its corrosive effect, brake fluid must not come into contact with paint work. Brake fluid is hygroscopic, meaning that it absorbs moisture from the surrounding air, and must therefore be stored in air-tight containers. During the bleeding procedure, brake fluid that has been flushed through must not be used again and must be disposed of properly. Observe disposal regulations --> Brake fluid .

Note. Only use new brake fluid conforming to US-Norm FMVSS 116 DOT 4. Genuine VW/Audi brake fluid conforms to this specification. Do not use any silicone-based fluid. Avoid contaminating brake fluid with particles or lint (e.g. from cleaning cloths). Rinse off spillages, by using plenty of water. Do not work with compressed air and do not move vehicle while the system is open. During the final road test, ensure that an ABS-controlled brake test is performed at least once (pulsation must be felt at the brake pedal).
