what does it do and how important is it?
Don’t do this. Buy the correct piece from Dr Diff. You will have a hard time removing the pushrod next time around. The correct piece has a notch in it so it will come out.Snip a small piece of 1/4 vacuum tube off your vacuum cannister or p/brake, or washer bottle.
As an add on to this; thanks for posting about that rubber piece.
I'm replacing the master cyl for the first time on my Barracuda (w/75 Dart manual front disc.) and didn't know about it until after I torched the old one out.
I too just found out the hard way too, I shredded mine trying to remove it.
Hmmm, mine just had rubber o-rings on it. I replaced the o-rings that where on there but haven't installed it yet. I also need the white plastic gasket that goes on the firewall behind the master cylinder. hopefully DR. Diff will have that too.
