That rod goes in a plastic piston. There's a rubber seal that goes between the piston and the case.

I've seen 0-ring type seals and flat rubber seals that are held in by the master cylinder. Unless the piston is broke.. the rubber seal is what's letting vacuum leak.

The O-ring type can be changed by pulling the plastic piston out.

Use to stay covered up at the shop with odd ball stuff like this.
