Have a 1978 F250 4x4 with DPC, looking at using one of the reproduction brake proportioning/metering valves. Has anyone used one of these? Any issues? Just looking at the valve, which I just got from Bronco Graveyard, I'm wondering if I'll get a pressure tight seal out of the rear port that feeds the rear brakes. It looks like a inverted 1/4" flare, not a typical inverted 3/16" brake flare. Not sure my brass adapter will seal to it? Any input?

 

I replaced the OEM valve with an adjustable one when I did my disc brake conversion. The original has about four different fitting sizes, so I did quite a bit of plumbing to get everything to a standard size for the replacement valve. A real PITA.

 

I ditched the factory PV and went with an adjustable Wilwood unit for $80. Alot less headaches and more reliable than the OEM crap which is right up there as one of the worse designs ever IMO.

 

HIO - Is your wilwood pv p/n 260-11179?

 

That's the one....

 

In my experience the "factory replacements" have extremely questionable quality, much less acurate proportioning. I used a Wilwood unit on a '65 Mustang I converted from 4 wheel drum to 4 wheel power disk at the dealership I work at. It is an easy unit to set up, you lock it and forget it.

 

Thanks!

 

Of course the year after I fabbed up my own bracket to install it Wilwood comes out with their own albeit at a price of around $35.

Below is the set-up on my '70. That's a brake switch on the front which can either be used or removed 9and plugged). I found it more reliable than the Flintstone mechanical switch on the brake pedal arm.
