    Opinions please,

    When driving, a push on the brake results in loud hissing which
    appears to come from the brake pedal area and minimal braking power. I
    have the shop manual and done the various tests which were somewhat
    inconclusive as there was little to no changes to pedal hight during
    the engine on and engine off pump and hold tests. I have vacuum on the
    booster side of the check valve.

    Brake fluid is close to full. No recent brake jobs.

    Thanks in advance,

    -Robert

    A vacuum leak in the booster when activated. Your vehicle is certainly
    old enought to warant a rebuild.
