OK guys,
As I have said before, the systems on cars and trucks are my weak area.

So I tend to spend a lot of time on the internet reading and re-reading stuff.
Here is the question.

I have a disc/disc master cylinder (2002 Silverado) and a disc/disc proportioning valve (Right stuff PV72 ) They both have no instructions. Some internet info suggests connecting the front port on the master to the front port on the proportioning valve. Some others indicate connecting them crisscrossed front master to rear proportioning and rear master to front proportioning. Apparently there is confusion (mostly on my part) concerning primary port/front brake on master cylinders that are disc/disc vs. disc/drum.

The proportioning valve ports info I have found on the web are shown in this picture. Maybe I am over thinking this.

The question is this, is the "rear" port on the master cylinder the port for the rear brakes?

Thanks
