Very nice, it sure does help having a visual of things
I appreciate it shine.
You dont have a close up of the brake booster and master cylinder.
I have noticed you had a combination valve.
I have been told for running disk and drum that I could run a propotioning valve and 10lb risidual out the back and on the front a combination valve and one 2lb risidual.

But I also have seen that you can run two 2lb risidual one for each side up front with a metering valve. SO I am getting a little lost.
