I can't find this part referenced in any parts manual parts catalog or the factory or service manuals.
There appears to be an orafice on the hollow bolt that goes through the brass block that shoukld line up with the side outlet. The hollow bolt will not come out of the block. It rotates freely and comes out a little ways then stopps like it was meant to stop.
I hope the pictures help.
does anyone have experience with this piece?
it's on the master cyclinder of a 53 3/4 ton.
