Thanks. I didn't realize until you mentioned it that the parking brake only operates the rear shoe. The linkage is clear and the springs were installed correctly. (Digital cameras and the Bentley made sure of that.) The shoes came with parking brake levers installed and they were painted, but loose enough. After a week of driving, the brakes have adjusted themselves pretty good and now the parking brake holds pretty well. (Wouldn't want to rely on it in San Francisco yet.) I think the adjustment combined with the new drums and shoes to made for an initially poor system.
