Hydraulic Components - Brake System (coupe) Audi A5 I

BRAKE SYSTEM, BLEEDING

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 (for example from cleaning cloths). Rinse off spills, 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 a ABS-controlled brake test is performed at least once (pulsation must be felt at the brake pedal). The brake system indicator light blinks when the brake fluid is too low or the ABS system or parking brake is malfunctioning.
