Maintenance - Edition 12.2020  
♦ Tool set for brake bleeding -VAS 6564-  
NOTICE  
♦ Never allow brake fluid to come into contact with fluids  
that contain mineral oils (e.g. oil, petrol, cleaning agents).  
Mineral oils will damage seals and rubber grommets of  
brake system.  
♦ Brake fluid is poisonous. In addition, due to its corrosive ef‐  
fect, brake fluid must not come into contact with paintwork.  
♦ 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.  
♦ Do not reuse extracted (used) brake fluid!  
♦ Observe relevant disposal regulations.  
Extracting brake fluid  
– Unscrew cap -1- from brake fluid reservoir.  
– Using the suction hose from brake filling and bleeding unit,  
extract as much brake fluid -2- from the brake fluid reservoir  
as possible through the strainer -1-.

Note  
The strainer in brake fluid reservoir must remain in place.  
Ensure that no brake fluid runs through the strainer after  
completing the extraction (the brake fluid level in the reser‐  
voir must be even with the lower edge of the strainer).  
Connecting brake filling and bleeding equipment  
– Screw adapter -1- onto brake fluid reservoir.  
– Connect filler hose from brake filling and bleeding unit to  
adapter -1-.  
– Set correct pressure on brake filling and bleeding equipment  
⇒ Operating Manual, and switch on brake filling and bleed‐  
ing equipment.  
Note  
The bleeder hose must be firmly seated on bleeder valve so  
that no air can enter the brake system.  
There must always be sufficient brake fluid in the brake res‐  
ervoir so that no air can enter the brake system through the  
reservoir.  
Start with front right brake caliper on RHD vehicles.  
Due to the tool attachment -VAS 6564/9- the rear wheels do  
not need to be removed any more.  
Front axle  
– Remove cap -1- from bleeder valve of front left brake caliper.
