1972 f250 brake problem

​This is my second post of this. I had it in the 73-79 forum on accident and i didnt know how to move it over so i am reposting I have a 1972 f250 with a 390 and disk brakes in the front. I'm having issues with the front brakes it leaking from the nipple thing on the distribution block or proportioning valve not sure exactly what it is maybe someone can help me figure it out or where I can get a new one or a rebuild kit of some sort ive tried looking everywhere only place i have found it was ebay and its gone now lol heres a pic of it hopefully it helps

C8TZ-2B161-A .. Metering Valve-Use with dual piston caliper disc brakes / Obsolete

1968/79 F250 2WD & F350 ~ No Ford dealer or obsolete parts vendor has any.

Note: Some 1973/79 F250 2WD's have single piston caliper disc brakes, do not use this valve.

It's not needed replace it with a brake line tee.

thought about doing that but didn't know how important it was. Figured it was there for a reason must have some sort of use besides being a splitter

The metering (hold-off) valve does have a purpose. It momentary blocks fluid pressure from going to the front discs, in order to give the fluid pressure acting on the rear drums time to overcome the tension of the brake shoe retracting springs and start moving the rear brake shoes towards the inner friction surfaces of the drums.

The momentary delay by the metering valve is designed to give the rear brakes a head start so that all four brakes apply at about the same time. Discs, without a hold-off, would apply immediately when the brake pedal is stepped on. Drums don't respond immediately because they have mechanical components to overcome before the shoes begin to make contact with the drums.
