Ford equipped the 1999 Windstar with single-anchor-type rear drum brakes. The brake shoes and the cable tension for the parking brake are self-adjusting. The self-adjusting levers activate as needed when you move the Windstar in reverse and apply the brakes.
If you work on the brakes yourself, be aware that asbestos from the brake lining is hazardous, so take care not to breath the dust. The minimum brake lining thickness for your Windstar is 3.9 mm and the maximum drum inside diameter is molded into the drum. You can adjust the brakes manually through access holes in the back of the backing plates, using brake adjustment tool No. 206-D003 or equivalent.
