[Vwdiesel] 85 Jetta TD Front brakes locking up

[Doyt W. Echelberger]

About a month ago my aging 85 Jetta TD developed a brake problem. I'd drive 
it about 5 miles and then the front brakes started dragging and making the 
engine labor. The front hubs got hot and were smoking, and I had to stop 
driving the car and let everything cool down.  This problem developed on 
the test drive after replacing the head gasket, which may only be 
incidental.  Same brake problem showed up about 6 months ago, and I swapped 
in a new master cylinder and the problem went away.

OK, I did some easy fixes....  First, I replaced the master cylinder. It 
was still under warranty and the replacement was free, so I just did it. 
That stopped the passenger side front brake problem, but the driver side 
front brake just kept on locking up.  "I'm gonna fix that," (sez I).....and 
replaced the caliper and both the hard line and the flexible hose on that 
side.   It didn't change anything except the thickness of my wallet.

Driver front brake still locks up after driving about 5 miles.

So, all the easy answers seem to be used up.   I'm obviously overlooking 
something....probably obvious to someone....or at least I hope so.     Help.
