Recently (as in weeks), I replaced the following:  brake master,
all brake hoses, rear brake lines.  Initially everything appeared fine,
but after about three miles I realized that my brakes were binding.

<Snip>

>When I got home I realized the problem still existed and jacked up the
car only to discover that none of the wheels would turn freely.  I
disconnected the hose to the master servo to make sure that that
pressure was released.  Whether it was the time that had elapsed or the
removal of the hose I'm not sure, but at this time the rear wheels would
turn, but the front wheels remained frozen.
 
I then cracked the front brake line at the master reservoir and that
allowed the front wheels to turn freely.
 
However, now I sit with a car that is basically not drivable and wonder
what to suspect?  Even thought the brake master is brand new, I cannot
think of any other culprits that would cause all four brakes to tighten
up and prevent mobility.

As an experiment, drive the car until the brakes start to hang up again. 
Then loosen the two nuts that secure the master cylinder to the booster
evenly, 1/6 turn each at a time, and see if the brakes free up.  If so then
the actuator rod in the booster, which was adjusted for your old master
cylinder, is too long for your new one.

Good luck

Dave
