Brake Fluid

Did it last month on both cars.
Volumes are from elsawin

Audi recommend about 250 cm3 of brake fluid to drain out per caliper in the following sequence. Add 250 cm3 to the first caliper to allow the contents of the master cylinder to changed to make 500 cm3 from the first caliper

1 - Rear right brake caliper
2 - Rear left brake caliper
3 - Front right brake caliper
4 - Front left brake caliper

On vehicles with manual gearbox the clutch slave cylinder should also be "flushed" with new brake fluid. Allow about 100 cm3 of brake fluid to flow out of the clutch slave cylinder.

1.5 litres in total should do it.

I'm not sure but if you car has ESP you need to hook it up to the diagnostics to change the fuid in the ESP circuit

Depends where you look at it from...

As bryzan said start from the furtherest caliper from the master cylinder.
1 - Rear right brake caliper
2 - Rear left brake caliper
3 - Front right brake caliper
4 - Front left brake caliper
This is as seen from the front of the car looking into the engine bay.
I assumed you'd get my drift and as they say "assumption is the mother of all f*@k ups"
