[Shotimes] rear calipers sticking

[Mike.Wojton@us.o-i.com]

I've been having a problem with my rear calipers.  When I release the
parking brake, they want to stick for a while.  So much so that the car
won't roll down my driveway on its own.

Both calipers are new NAPA units.  In fact, I replaced one of them
again because the replacement leaked around the piston.  The slide
pins should still be greased up good.  The cables were just replaced
last month.  The shop that did the cables played with the adjustment,
and they're convinced that the calipers are sticking.  They had the
cables adjusted so far out that when the pedal was released, there
was no tension on the caliper.  I'm convinced.

This only happens when it is pretty cold out.  (of course, it's going to
start happening alot more now)  What are the odds that the calipers
are bad again?  Maybe a batch of calipers were remanned with too
tight of tolerance in the pistons?  Or, because it only does it when
it's cold, if the caliper housing and the piston were different materials,
they contract differently in the cold?  I thought I read where they can
have steel or phenolic pistons.  I won't know what I have until I take
them off again.

So, anybody ever have this kind of problem before?  Any comments?
Constructive, that is.  ; )
