I think I'm gonna try to rebuild this one cause it looks to be in good shape. There are lines running to all four corners but someone (I doubt it's factory) had run a line up to the engine compartment but crimped it over but can't figure out what they had in mind? Is there anything factory that it would have connected to? I've seen the diagram in Classic Parts mag and the other lines look right except that line is not on there. Also which type of brake fluid does it take?
That extra line may have been for a brake light pressure switch. I just put in a new brake line system and it was easier to put in a pressure switch for the brake lights than to try using the old brake switch.
