Joe,
Are the front flexible brake hoses original to the car? They have been
known to cause problems like this. The internal lining of the hose breaks
down after a number of years and begins to seperate from the outer sheath.
This will cause problems as the partially seperated inner lining will act as
a check valve, allowing fluid in and then trapping the pressure in the
calipers. After a short period of time the pressure will slowly bleed off
the calipers, allowing free movement.
