Hi
I've replaced the discs and pads on the wife's A3, had to remove on back caliper and detached at the banjo. Bled just this section and now I am getting the pedal sinking under load with the engine running, turn off the engine and dispel vacuum in servo and you get a firm non sinking pedal.

Have I got air in the system or is it master cylinder?
and other ideas/ experiences?
