<VV> Sticking Wheel Cylinder

[Harry Yarnell]

I'm trying to imagine why the wheel cylinders would seize up with silicone
fluid in them.
I'd have a helper push the pedal while you try to turn the tire (unloaded,
of course), to see who, if any are sticking.

I'm looking for the experience of others on this.  My Corsa had new  wheel 
cylinders installed by a trusted Corvair mechanic when I didn't have the  
time.  He used the silicone DOT 5 fluid I supplied to flush and refill the  
system.  After about six months (mostly of sitting with a few trips of 40  
miles or less) the left front cylinder started to seep brake fluid (I use  
silicone DOT 5 unless I can drive the cars several times a week).  I  took
the 
car off the street in front of the house and put it in  the driveway to 
trouble shoot, but winter intervened and I didn't get to it  until spring
when I 
noticed that the seeping had stopped--apparently from just  exercising the 
brakes.  The pedal is too hard now and I don't trust the  system so I plan
to 
hone the two front cylinders, flush the whole  system and refill with 
silicone DOT 5.  
 
I don't do brake jobs that often anymore, but I usually get them  right.  
Has anyone else had this sort of problem?
