OK, let's go over this one more time. Our valve is a solid block of brass. I don't know if it's original, but from the '78 GM' stickers I found on the rubber brake lines, it probably is. On the 'front' end of the valve body is a little rubber cap with a tab. If you pull this cap off. there is a hex headed thingy with a hole in its center. If there's a pin in the hole, it's not sticking out.
Now, the front chamber of the MC (with the larger brake line) is for the rear brakes, right? So if I disconnect this line at the MC, I can flush the line out to both sides of the rear brakes, yes?
I've rebuilt the entire rear brake system to date. I will do the front system after Bean. But now I just want to get the rears going.
So, do I have to do anything with the proportioning valve for this exercise?
Thanks for the astute answers I'm going to receive from the greatest collective GMC minds on the planet!
