This looks like if it isn't replaced properly it could lead to a very unsafe condition!
After reading this article and before purchasing Speedbleeder, I will make sure my stock bleeder and the new Speedbleeder is compatible in, thread pitch,size, outside measure etc
Keeping in mind that my old pickup would never go through as much hard use as in a race track situation, this is a very good Idea, but I think just to be on the safe side,it deserves to be further researched.
