OK, so the new rotors have been cryo'ed, the front and rear callipers have been rebuilt and laquered red, the SS brake lines are in place, the new 25mm master cylinder is installed and the new metal brake line is in. Now, the question. Does the car have to be running to purge what's left of the old fluid out and fill it with Super Blue, or can I just pump the pedal. The reason I ask is that I have about a week until I can get to a point to start the engine again.
