Running gearBleeding brake system
WARNING | t
| Do not under any circumstances allow brake fluid to come into contact with fluids that contain mineral oils (e.g. oil, petrol, cleaning agents). Mineral oils damage the plugs and seals in the brake system. |
| t
| Brake fluid is poisonous and must NOT be drawn off by sucking through a hose. Because of its caustic properties it must also not come into contact with paintwork. |
| t
| Brake fluid is hygroscopic, i.e. it absorbs moisture from the surrounding air, and should therefore always be stored in airtight containers. |
| t
| Brake fluid flushed out during the bleeding process must not be re-used and must be disposed of in the proper manner. |
| t
| Always observe the relevant environmental regulations for disposal → Chapter. |
|
Note | t
| Only use new brake fluid conforming to US standard FMVSS 116 DOT 4. |
| t
| Genuine VW/Audi brake fluid conforms to this specification. |
| t
| Do not use liquids containing silicone. |
| t
| Avoid contamination of brake fluid with any dirt particles or bits of fluff (e.g. from cleaning cloths etc.). |
| t
| Rinse off spillages using plenty of water. |
| t
| When the system is open do not work with compressed air and do not move the vehicle. |
| t
| During the final road test, ensure that at least one ABS-controlled braking operation is performed (pulsations must be felt at the brake pedal). |
| t
| The brake system warning lamp flashes if the level of the brake fluid is too low, in case of a malfunction of the ABS or a malfunction of the electronic parking brake. |
