Rear brake not releasing correctly

[Kneale Brownson]

I'll bet that if you take the piston out of the caliper, you'll find some 
corrosion on the walls of the caliper  cylinder or on the piston.  The 
external spring on the  cable can move the arm all the way to its stop and 
the brake piston still won't retract totally if there's some rust on the 
piston or cylinder walls to cause some friction.
