[200q20v] Rear Caliper sticking?

You're right that the rear caliper hangs up under my scenario regardless of 
how the piston is moved against the brake pad, Phil.  That was my personal 
experience:  The rear calipers dragged from use with just the pedal.   I've 
never had an elderly car with a cable brake that didn't have problems with 
the cable brake, so I've just gotten used (in nearly 50 years of driving) 
to not applying the emergency brake.  Folks who experience dragging only 
after using the emergency brake must have a problem in the cable system if 
the cable lever on the caliper is free.
