<VV> Sticking Wheel Cylinder

[HallGrenn at aol.com]

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?
