Is there an adjustment on the back brakes of Ford Freestar van?
No, the Ford Freestar (and its sibling, the Mercury Monterey) do not have rear drum brakes with manual adjustments. The rear brakes are self-adjusting. If the rear brakes need adjustment, it's typically a sign of a more serious problem requiring professional attention, such as worn brake shoes or a problem with the self-adjusting mechanism. You should not attempt to manually adjust them.
