Your Windstar is subject to a Ford recall for the cause of this problem.
The cause is a leaking brake pressure sensor screwed into the bottom of the master cylinder.
I would suggest contacting your Ford dealer confirm your van is covered (I believe every single Windstar is part of the recall), and arrange for the quick and easy repair.

The California annual mileage and odometer certification for this vehicle is a document that verifies the mileage on the odometer is accurate and has been certified annually in the state of California.
Records mileage and speed of the vehicle
The mileage indicator in a vehicle is called an odometer.
Read it from the odometer - a total mileage recorder usually on the speedometer dial.
When a vehicle's mileage exceeds mechanical limits, it means that the odometer has reached its maximum value and can no longer accurately display the true mileage of the vehicle. This can occur if the odometer has rolled over, typically after it reaches 99,999 miles or 999,999 miles depending on the type of odometer. This makes it difficult to determine the true mileage of the vehicle and may raise concerns about its actual usage and wear and tear.
The certified accurate mileage of the vehicle, or a statement that the odometer is non-functional and the exact mileage of the vehicle is unknown.
Relates to the Odometer Codes on the Arizona Department of Transportation Vehicle Division, Title Registration Application.

Definition of Exceeds Mechanical Limits :A vehicle with a 5-digit odometer cannot accurately track mileage after 99,999 miles because the odometer rolls over. This title is the result of a seller certifying under the Truth-in-Mileage Act, that the odometer reading EXCEEDS MECHANICAL LIMITS of the odometer.
When a digital odometer is replaced, the mileage typically does not erase automatically; however, it can be manipulated if the replacement is not done by a professional. In many jurisdictions, tampering with an odometer is illegal, and ethical practices require that the new odometer reflects the true mileage or that the discrepancy is documented. It's essential for vehicle owners to retain records of odometer replacements to maintain transparency regarding mileage history.
The 2000 Cadillac Escalade has a 6-digit odometer. This allows it to record mileage up to 999,999 miles. If the vehicle's mileage exceeds this limit, the odometer will roll over back to zero.
