No pressure at all? The proper sequence is to apply the brake lever, then open/close the bleeder before the lever reaches the grip. Opening the bleeder first will let air into the system before the lever is squeezed.
The next thing is the banjo fitting at the master cylinder. It is like a hollow barrel, and the bolt that holds it has a hole drilled to let the fluid pass. This can often be bled by making the fitting lower than the master cylinder, and cycling the lever. Pull the lever slowly, hold a second, then release it quickly; repeat. This will usually pull the air back into the master cylinder and out. Last resort is to loosen the bolt, keeping the fitting snug enough not to leak, then use the same procedure you use with the bleeder: apply pressure, loosen then tighten the bolt before the lever reaches the grip. Messy, so make sure the fluid can't spill on anything painted or polished, it will stain and strip paint.
