My Cobra (that I just purchased) has a HTOB in it - about 2500 miles on it. Now you all have me a little worried about it. Thanks.

Now I have to ask, are the slave cylinders having O-ring failures as well? I know they are much easier to change. What I am trying to figure out is if the failures are related to a change in the rubber chemicals that the O-rings are made of.

We had a bunch of rubber coated roller failures at work about a couple years back and traced it to a chemical change in the rubber compounds. Fuzzily I seem to remember the tree huggers stopped production of some chemical that was used. They have since improved the rubber to a tollerable level, but still not as good as it was.
