904 question. Please help.

nothing wrong with using atf+4 in 904....

but type 7 would work just as well...

never seen a 904 blow fluid out of the vent.....i got two of them with transbrake and never experience any of those problems..

The last & only T/Brake I had was in my Super Street Duster with a 727.
This was in 1995, it was a Tubo Action. This is how Paul @ T/A instructed me to install it. This may not be a concern on the newer brakes, as there are several different brands available now.
