A vac system will work OK, but a faster, easier one-person procedure
is to _pressure_ bleed, using a cap fitted with a Schraeder-valve on
the brake reservoir. To provide the low pressure that's needed, you
can use a commercially available hand-pump bottle. I simply use a
spare tire (lowered to about 15 psi) to pressurize the reservoir.
It's connected via a cheap12-ft coiled pressure hose fitted with a
couple of locking-type air chucks ($5 at Pep Boys). Complete
brakeline bleed can be done by one person in about 30 minutes.
