brake fluid  
Operation and safety notes  
Note  
From model year 2006 a new brake fluid is used.  
The new brake fluid can also be used for older vehicles.  
For this purpose it can be mixed with the previous brake fluid.  
WARNING  
♦ Never allow brake fluid to come into contact with fluids that  
contain mineral oils (e.g. oil, petrol, cleaning agents). Min‐  
eral oils damage the seals and boots in the brake system.  
♦ Brake fluid is poisonous. In addition, due to its corrosive  
nature, it must not come into contact with paint.  
♦ Brake fluid is hygroscopic, which means it absorbs mois‐  
ture from the ambient air and should therefore always be  
stored in air-tight containers.  
♦ Rinse off spilled brake fluid using plenty of water.  
♦ Observe relevant disposal regulations.  
♦ Do not reuse drained (used) brake fluid.  
Brake fluid specification  
♦ Brake fluid conforming to US standard FMVSS 116 DOT 4  
(previous brake fluid)  
♦ Brake fluid conforming to VW standard, VW 501 14 (new brake  
fluid).  
Procedure, changing brake fluid  
Special tools and workshop equipment required

♦ Extractor bottle  
– Extract as much brake fluid as possible using suction hose  
from brake filling and bleeding unit - VAS 5234- .  
– Connect brake filling and bleeding unit to brake fluid reservoir  
(do not switch on).  
– Fit brake pedal actuator - V.A.G 1869/2- between driver seat  
and brake pedal and pretension.  
– Switch on brake filling and bleeding equipment .  
Vehicles with manual gearbox  
– Connect bleeder hose -A- on slave cylinder and open bleeder  
valve.  
– Allow approx. 0.1 litre of brake fluid to flow out.  
– Open bleeder screws of respective brake calipers and allow  
the corresponding brake fluid quantity to flow out (see follow‐  
ing table). Used brake fluid is pushed out of the system by  
pumping in new fluid.

Brake fluid level (dependent upon brake  
pad/lining wear): check.  
♦ Instructions for use and safety ⇒ page 98  
♦ Brake fluid specification ⇒ page 98  
Please note the following:  
Delivery inspection:  
At delivery inspection the fluid level must be at MAX. marking.  
Note  
To prevent that brake fluid flows out of reservoir, the MAX marking  
must not be exceeded.  
Inspection service:  
– The fluid level must always be judged in conjunction with lin‐  
ing/pad wear. When vehicle is in use, fluid level tends to drop  
slightly due to lining/pad wear and automatic adjustment.  
– When fluid level is at MIN. marking or just above, fluid should  
not be topped up if linings are almost at wear limit.  
– If linings/pads are new or well within wear limit, then fluid level  
must be between MIN. and MAX. markings.  
– If fluid level is below MIN. marking, the brake system should  
be checked before fluid is added. (repair measure).
