My front reservoir goes empty quickly. I cannot detect any leaks at any wheel or master cylinder. Although when pumping the breaks, I can hear what sounds like liquid or air, going through a hose from the brake booster to the power steering reservoir . That reservoir's level doesn't change.

you definitely have a leak. remove rear wheels and remove drums and inspect wheel cylinders for leaks. also look under dash where braqke rod goes through firew2all for wetness, if it is replace master cylinder
