A liter is generally plenty, if you really want to push it all through you should also run the ABS system tests with a suitable scan tool as well.

Thanks does our power steering need a fluid change ever? Im just trying to keep my mk4 in the road for 600k plus miles currently at 480k and will be performing 4th TB service among other things. Thanks

If you want to suck the reservoir out and replenish with new it certainly wouldn't hurt anything. These don't typically have much power steering problems.

In my experiance on a dirty system the brake fluid needs to be changed a 2nd time after a week of driving. New clean fluid tends to clean more than what just came out.
You can pop the resiviour off and clean it with brake parts cleaner and let it dry. If you are carefull you wont add issues to the master.
Going with a vac or pressure bleed you need to pump the pedal at least a few times on one of the bleeds. This gets the remaining bits out of the master that otherwise cant leave.
You dont have to but it's good if you cycle the abs pump with vcds.
