how to bleed vectra b brake system?

Start furthest away from your master cyl, probably n/s rear, keep brake fluid topped up. Sometimes you can let gravity do the job for you, just open each bleed screw in turn and see if you get a constant flow from the bleed screws,it can take a while depending on how much fluid has drained from your system, if not then you will need a helper to pump your pedal, you can open bleed screw/press pedal to floor,close bleed screw,pedal up and so on and so on until you get a constant flow from each screw,catch excess fluid in an old duster. Another way is to get a jar with some fluid and a small hose onto the bleed screws,keep other end immersed in the fluid,open screws and pump away until you get rid of all the air from your system, if neither of these work then it will probably need a pressure bleeder to sort out your brake system,good luck.
