Hy txpete, you must bleed the Hydrovac first the bleeder at the the end of the cylindrical projection then the one on the top of the major diameter of the unit. Then from memory right rear, left rear, right front, left front, but I will confirm that with a check in the maintenance manual, you may use any method that you choose to bleed the brakes, however pressure bleeding seems to give the most trouble free results, hope that helps.
