I am English not Czech I just live here. I was trying to say WHEN would the do you need the system completely bled. In what situation.
Max- In that case your Czech may be no better than mine. The system needs to be bled when you do major surgery or replace (God forbid, they are expensive) one of the F1 lines, or suspect you have air in the lines from a leak. There is no scheduled activity in the OM, warranty book, or WSM for bleeding the F1 system, but then there is none for anti-freeze, either. Maybe Brian can chime in. Taz Terry Phillips
