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.
Do you
have the same problem?

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

You're right. Once I parked on pavement and tried the brakes, I found a leak in the rear line just in front of the wheels. Thanks
