[V6-12v] Brake Bleeding

The bomb. Audi's have a high-pressure reservoir that store brake  
pressure (about 30 to 50 ATM's worth, if I recall correctly). You  
effectively discharged it when you bled the brakes. About 50 pumps of  
the brake with the car running should reset everything back to normal.

How to test the bomb:
Engine off, pump the brakes and count how many pumps it takes for the  
peddle to get mushy. Under 25 or so, and the bomb has seen better  
days. Under 15 and it's high time to replace it. Under 10 and you are  
in the danger zone.
