Default Proportioning valve questions

I am swapping a set of Granada disc brakes onto my wife's 66 Mustang, and I need to install a proportioning valve. I have the valve that came with the disc brake setup, but I don't know which fitting goes where. Can anyone help me identify which goes to the left front, right front, rear, and master cylinder (front and rear)? Unfortunately, I can't figure out how to attach a picture....I will be using a Granada master cylinder.

Thanks,

Proportioning valve, or distribution block?

Well, both. I have a distribution block, and one of the lines has an inline thing that I presume is the proportioning valve. I am used to GM cars where everything is in one unit....

Have to state this as it is.

You are installing brakes on your classic--You have no idea of how brakes work (Very apparent in the questions)--You need advise that can be correct, or incorrect--????

Have you thought about taking this to a qualified, knowledgeable person??

Stopping is very important here.

Back up for a second...I never said I don't know how brakes work. I said I have a distribution block and proportioning valve here and I don't know which line goes where (I didn't pull it off of the original car it came from). I have built dozens of cars and trucks, and worked in brake testing of prototype cars for 7 years, so I know very well how brakes work. I have just never built a Ford, and I am not familiar with the distribution block I have. If nobody here can assist me, I will just have to figure it out for myself....maybe I'll just install a GM combination valve on it. I have several of those.

67Mustang302, I would post a picture if I could figure out how (I am not all that computer literate).

Thanks,

FWIW I tossed the POS factory distribution block and just run a T fitting to split the front left/right and run an adjustable prop. valve in the line going to the rear. All Wilwood.

Edit: Actually, it used to be that way, now it uses a Wilwood part. http://www.wilwood.com/MasterCylinde...emno=260-11179 Has the prop in the rear, and splits the front for left/right, but the 2 sides are totally isolated. It also has a brake light pressure switch built in to it.

I've finally removed my proportioning valve altogether on my '67 and just replumbed it in the stock configuration in the distro block. After experimentation, I could not see where it made a difference in actually stopping the car.

I know everyone gets all bent out of shape on how "critical" brakes are, (and they are critical) but seriously; they work on well-recognized principles, and really aren't that hard to learn and do. Especially disc brakes.
