Brake booster or master cylinder?

How do you tell if it is the brake booster or master cylinder on 1995 Chevy Blazer LT 4x4 going out?

Brake booster failure will make the pedal hard with no assist
The master cylinder will bleed down ...as you put pressure on the brake pedal it will slowly go to the floor
