Use a Mityvac hand pump vacuum bleeder and a set of speed bleeders with a spring-loaded check valve to prevent air from getting sucked back into the wheel cylinders. Harbor freight has a Mityvac knockoff pump that works pretty well. Be sure to keep the master cylinder reservoir full to avoid getting more air into the system.

If you choose to use a helper on the pedal, DO NOT pump the brake. Push the pedal a time or two and hold it down, then open a bleeder. Repeated pumps on the pedal breaks the air up into tiny bubbles that are very hard to get rid of.
