Paul, I like the power brake bleeder that is available from Motive products.
It is not exactly inexpensive, however. It bleeds the system well, and turns it into a one person job. It also makes quick work of flushing the brake fluid out of the system. Bleed in the order of - right rear, left rear, right front, and left front.
While you're doing things, check for leaky rear wheel cylinders, and manually adjust the rear brakes by pulling the drums. Both of those have been known to be an issue.
