I'll put this on the list because in my own club it's such a common
question/concern. Some models of cars do seem to "use" seals for one
reason or another. However, depending on what Ian means by not lasting
very long, it's likely that the cylinde rhas been rebuilt one too many
times. I know they're expensive, and that's why POs have not done it
either. The tolerances are so fine that if there is :
- any piiting on the cylinder walls
- any pitting on the piston
- a ridge where the piston sat all winter.
- general lack of smoothness on eith er of the above
then the seals will last a very small amonut of time and every summer
it's the same deal.
On rare occasions , when you find fluid on the floor afte the first drive
of the season, it's crude the has built up ove rthe winter and a
cleanings will do the trick. It's the same after a rebuild. So often
people tell me that "right after the rebuild" they get a problem, maybe
even the psiton sticking up in the bore ! It's becasue during the
rebuild and bleeding the piston travels into places where it does not
normally go and the seal gets eaten up.
With a clutch you can diddle along, but if it's a common master or it's
the unit for the brakes then replace it. The two hundred dollars is cheap
compared to banging up your car or some kid on a tricycle!
