fluid filling a completely empty brake system
 

helo,
i was restoring an fd and need to remove all the brake lines and abs unit for painting the body.
now i am ready to put new fluid at the empty system. is there anything i should take care regarding the abs or i just keep adding fluid at the tank and vacium the caliper bleeder until i see fluid?
probably the abs is full of air. can someone please advice me how to remove it?
thanks!!

just fill and bleed it like any other brake system.
