Most likely the adjustment of the push rod between servo and MBC is out.

        <div>Hello all,</div>

        I've had a bit of problem with the brakes locking this season. 
        After it happened the second time, I pulled the vacuum line form
        the servo and plugged it.  I put a few hundred miles on the car
        with the vacuum line off the servo, and the brakes have worked
        great.
        <div><br>
        </div>
        <div>This morning, I backed out the driveway, and I noticed the
          car wouldn't roll downhill.  I pulled it back into the garage,
          and jacked it up to see where the wheels were locking.</div>
        <div><br>
        </div>
        <div>The rear wheels turned freely, slight drag on the right
          rear.</div>
        <div><br>
        </div>
        <div>By hand, the front wheels would not turn at all.  Neither
          one.</div>
        <div><br>
        </div>
        <div>Does unplugging vacuum from the servo completely remove the
          servo from the equation?  Could a servo without vacuum still
          cause locking problems?   I believe my servo is a Lockheed
          unit, put on by the PO, and the servo doesn't look that old.</div>
        <div><br>
        </div>
        <div>The front calipers are recent rebuilds (2 years ago).  
          Anything else that could cause the front brakes to lock up?</div>
        <div><br>
        </div>
        <div>thanks!</div>
