Just pull the reservoir down with a gravity bleed off the left front. Won’t take long and frankly is the easy button.
On a side note don’t let the MC go dry on and ABS equipped car as the only way I know to bleed an ABS system is to pressure bleed it. Have heard a person can lock up the ABS pump piston if the MC goes dry and the system is manually bled. Could be wrong so I just pressure bleed mine.
