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.
